MacOS X – ApplePi Baker – Prep SD-Cards for IMG or NOOBS

MacOS X – ApplePi Baker – Prep SD-Cards for IMG or NOOBS

After writing the article on “How to get an Operating System on a SD-Card“, I realized that the existing methods and tools were to my liking. Of course the existing tools are most certainly not bad and work just fine. I just didn’t like how they worked.

So instead of complaining, I decided to write my own program: The ApplePi-Baker 

This application is for MacOS X only and allows you to prepare an SD-Card for use with Raspberry Pi’s NOOBS, and it allows you to “flash” and IMG file to an SD-Card. ApplePi-Baker can now also be found on and

Note : This application is also very suitable for creating or restoring an IMG  backup of USB drives!

ApplePi-Baker – Overview

For MacOS X users that have read the article on “How to get an Operating System on a SD-Card“; there are several ways to flash an IMG file on an SD-card, or create NOOBS SD-cards.

None of these tools or methods were to my liking so I threw together an application that can do it the way I like it: The ApplePi-Baker.

Changes in v1.6:

- Compression for Restore and Backup on the fly (ZIP, 7ZIP and GZIP).
- “Abort” button to abort a restore or backup process.
- Authentication through SUDO instead of the Apple Security dialog (please report issues).

Changes in v1.5/v1.5.1:

- Compression of Backup IMG to a ZIP file (with progress-bar).
- Supports USB drives now as well.
- Compatible with other filesystems like ext3 or ext4.

Changes in v1.4:

- Bug fix (SD-card size)
- Speed improvement

Changes in v1.3:

- Minor bug fixed in detecting SD-Cards and SD-Card readers
- Cosmetic change: Window wide oriented
- Cosmetic change: All elements are now Retinizer compatible (use it to make it Retina style)
- Cosmetic change: Removed resizer icon (lower left corner)

Changes in v1.2:

- Fixed minor bug with USB SD-Card readers
- Changed “Look” a little bit

Changes in v1.1:

- Improved SD Card detection: detect weirdly partitioned SD-Card (after screwed up dd) properly
- Fixed error message after clicking “Write IMG to SD-Card” and not selecting a file
- Fixed random numbers in speed and ETA indication at startup of IMG writing
- Added filesize vs SD-Card size verification
- Added option to backup an SD-Card

Some key points:

  • It’s FREE!
  • Easy detection of the SD-Card device
  • Quick creation of NOOBS disk
  • Fast flashing of an IMG file to SD-Card
  • Easy way to create an IMG backup of your SD-Card


Copyright, Pricing & Liability 

It appears that stuff like this is needed, so before you start using ApplePi-Baker:

  • This application is TOTALLY FREE! Nobody is to charge you a penny for it … and yes it’s copyrighted!
  • You’re using the application at your own risk – so it can fry your computer and make your house implode …
  • I created this application for MY OWN personal use – so keep in mind that I’m not your personal helpdesk.

ApplePi-Baker – Interface

The interface of ApplePi-Baker is straight forward (and yes I tried to be funny) …

You’ll find 4 “sections” in the ApplePi-Baker screen.

  • Status bar
  • Pi-Crust: Possible SD-Cards
  • Pi-Ingredients: Build a NOOBS SD-Card
  • Pi-Ingredients: Flash an IMG file to SD-Card
  • Pi-in-the-Freezer – Make an SD-Card backup


Retina Users 

For those that use a Mac with a Retina screen: Use Retinizer to make the application look better on a Retina screen (Thank Thorin for the tip!).
Unfortunately, at this time anyway, Lazarus Pascal still uses Carbon components, …


MacOS X ApplePi-Baker - User Interface

MacOS X ApplePi-Baker – User Interface

As of version 1.6, an Authentication window will appear at startup, which will ask your user password. This is the password you use when logging into your Mac and is needed for SUDO access.  Rest assured, the password will not be saved and the password will not be used in command line statements (ie. remains invisible in process manager lists).

Per session the password will only be asked once. After restarting ApplePi-Baker, the password will be asked again.

As far as I know, this should work for every user, however the user should be member of the Admin user group (I believe this is done by default). Please report issues in the comments below.

Selecting your SD-Card

The “Pi-Crust: Possible SD-Cards” section shows a list of possible SD-Card devices. This can be a SD-Card in the card reader in your Mac or an USB-Card reader.

The device is indicated as the actual device name (i.e. /dev/disk1), including size (i.e. 16.6 Gb) and the protocol (USB or SD).

The list can be refreshed by clicking the refresh button (top right) and a selected device can be ejected by using the eject button (bottom right).

How to create a NOOBS SD-Card

After clicking the desired device, click the “Prep NOOBS Card” button in the “Pi-Ingredients: NOOBS recipe” section.

This will first erase the entire disk, create one single partition (MBR) and format it FAT-32 so it will be ready for NOOBS use.
More details about NOOBS can be found on the Raspberry website or in “How to get an Operating System on a SD-Card” article.
Simply put: unzip the NOOBS ZIP file and drag the files on the SD-Card and boot your Raspberry Pi with this SD-Card.

How to flash an IMG to SD-Card

In the “Pi-Ingredients: IMG Recipe” section, one can flash an IMG file to your SD-Card.

Clicking the “IMG to SD-Card” button will open a dialog, asking you to select an IMG file or a compressed IMG file (ZIP, 7Zip, GZip).
If however you used the “” button next to the “IMG file:” field, then no file dialog will appear and the file selected there will be used instead (practical if you’d like to flash the same image more than once).

The process for flashing an IMG is a little more complicated:
First the device will be totally erased and a single partition will be created (FAT-32/MBR).
After that the partition will be unmounted and the IMG file will overwrite the entire device (just like when you use “dd”).

Both speed and ETA will be indicated in the status bar.

How to create an IMG backup of your SD-Card

Creating an SD-Car backup is easy: simply select the device you’d like to backup, and click the “Backup SD-Card” button in the “Pi-in-the-Freezer” section.

This will create an IMG backup of your SD-Card with the option to Zip, GZip of 7Zip de IMG file on the fly.
Note that the filesize of the backup, no matter how much space you use on your SD-Card, will be exactly the size of the SD-Card.
Restoring such an IMG file might come with complications when the target SD-Card is not exactly the same sime (or bigger).

Both speed and ETA will be indicated in the status bar.

Abort Button

As of version 1.6, an “Abort” button has been introduced, allowing you to abort/cancel any restore or backup process.

Be aware though that aborting a restore might leave you with a corrupted SD-card or USB-drive – repartitioning or restoring another image will make the card or drive useable as usual.

The button only appears when a process can be aborted.

    Just download and use ApplePi Baker. Love it so much. Thanks. It’s outstanding from others. 

    Could it support Retina-display in next version? The current display is too low to display correctly on Retina-display (screenshot here: 



    • Feb 11, 2014 - 11:28 AM - hans Comment Link

      Hi Thorin,

      Nice to hear that you like it, thank you for letting me know … 

      As for Retina support: Yeah, I’d love to, but I’ve developed this app with Lazarus Free Pascal, which doesn’t support Cocoa natively yet (needed for Retina) and still relies on Carbon  … as soon as Cocoa is support I will release a Retina version (I have a Retina Macbook pro so I’d benefit from it myself as well).

      Thanks again!



      • Feb 11, 2014 - 12:04 PM - Thorin Comment Link

        It’s nice to know that you got a plan with Retina display. Your app, again, is very stable, reliable and hit the nail on the head. I have just found out there’s an app named Retinizer for better display with ApplePi-Baker. You can try it here: It can help a little bit while we’re waiting for Cocoa. 

        One more suggestion, I realized that the height of the app is much longer than the width, and we cannot adjust it. It’s not proportionate at all (on our screen display, the width is longer than the heigh, right?). It’s just my suggestion, and it’s still your call. 

        Because I love your app, thus I always wanna it better. 



      • Feb 11, 2014 - 12:21 PM - hans Comment Link

        I had never heard of Retinizer … interesting App, but it seems that it doesn’t modify the binary, just on a per user level?
        I’ll have to play with it a little bit. But it’s most certainly a good tip for other users.

        I do like you suggestion, so I’m taking note of your request to make the app wider, so everything appears a bit more proportion.
        Depending on when Cocoa support will be available for Lazarus, I’ll modify the interface at the same time or before Cocoa is supported.

        Thanks again!

          Per you suggestions:
          Made the app wider, and I replaced the components that didn’t work well with Retinizer … (except for the logo image).

          Hope you like it … Enjoy!

      Hi Hans!

      Very nice works! It works without problems!

      Only one thing tha probably is a little bug(little!!)

      When I make a SD backup and try to restore it (on the same SD) an alert appear and it say that the img size is a bit bigger than SD size! If I chose “continue” the restore is successfull…

      Any explanation?? Thank you for great work!!



      • May 1, 2014 - 9:19 AM - hans Comment Link

        Hi Pierluigi! 

        Glad it works well for you as well …
        As far as the image goes: it uses “dd” to make an image of the entire SD card.
        The fine details why an image might be a few bytes bigger than the size of the original SD card is a mystery to me as well.
        I’ll have to look into that, it might also be a “rounding” error.

  • Apr 8, 2014 - 12:20 PM - Justus Comment Link

    It’s not working (Mac Mini 2012 i7, 16 GB Ram, 8 Core) with newest Mavericks. After Partition sequence I’ve seen a Popup with a Security warning to enter the admin passwort. After 1 seconds #Ve entered the password the app is writing “done”. But nothing is written (8 GB SDCard, Avaliable Space: 7.96 GB). 

    How I can solve that?



    • Apr 8, 2014 - 12:30 PM - hans Comment Link

      Hi Justus,

      I (and a lot of others) am running this app under Mavericks (10.9.2 on a MBP Retina [i7 Quad core], a regular MBP [i7 Quad core], and a Mac Pro [2x Xeon Quad core]) as well without a problem, which is of course not helping your situation.

      Are you sure you’re entering the right password (caps lock etc)?
      I know it’s a trivial (and often annoying) question, but the response of the app makes me think that your password was not sufficient for sudo (root) access.



      • Apr 21, 2014 - 11:40 PM - Sully Comment Link

        I too am having the same problem as Justus.  I was able to back the current .img I had on my Pi 8Gb SD card but when I selected a new .img to test it ask for admin password (yes I entered in correctly) then is goes to done/complete a few secs after that and it did nothing.  I also tried the prepare to format it and it does the same thing.  Asks for password and is done really quick and it never formatted the SD.  Using a 13″ MacBook w/ 10.9.2.



        • Apr 22, 2014 - 6:58 AM - Sully Comment Link

          So I purchased a new SD Card and also rebooted my MacBook Pro and now it’s working just great “baking” .img files to the SD card.  Maybe a funky SD card maybe the Mac just needed a good ol’ reboot.  Thanks for making some great software though!  Keep up the great work.

    Version 1.4 has been released today, addressing a minor issue with calculating SD-card size and IMG size.
    A minor speed improvement has been added as well.



  • May 5, 2014 - 12:20 AM - Thorin Pham - Author: Comment Link

    I’m guy that suggested you some UI features (Retinizer compatible, horizontal view…) in version 1.3. Noticed that version 1.4 has been fixed some problems about clone and restore SD card image. Couldn’t more excited every time ApplePi Baker has it own update. 

    Just one more recommendation, could it clone/backup SD card without empty space? Indeed we don’t use whole space of SD Cards. Currently, I’m using about 3.5GB/7.9GB, and “backup SD card without empty space” can help us restore SD images to different types of SD card, and of course, save more space for hard disk.

    Thank you!


    Thorin Pham

    • May 5, 2014 - 8:28 AM - hans Comment Link

      Thanks for the compliment Thorin 

      Cloning without the empty space is a little tricky. There are 2 scenario’s:
      - The partition is 100% of the SD-Card but only part of the partition is used
      - The partition is only using part of the SD-Card

      In the first case, it’s had to determine what is being used and what not, and to clone it one would need to resize the partition.
      In the second case, it will be a challenge to image the SD-Card and keep it bootable for the Raspberry Pi.

      The base of ApplePi-Baker is utilizing “dd” which does not offer any means to either.
      An external program like Gparted would be needed to resize the partition down to it’s minimum size.

      I’ll look into this and see what I can come up with, but I’m afraid it’s more complicated than one would hope it would be … 

      Ideally, one would like to image only the actual data and offer the option to use the entire SD-Card when restoring. Right now I do not have the mean to do so.



    • May 6, 2014 - 6:22 PM - Sashmo Comment Link

      When you boot an image for the first time it will load the raspi-config screen, and give you the option to expand file system.  Thats what I do.  If not, then apt-get install raspi-config, and then run raspi-config, the second option down is expand filesystem…..




    • May 7, 2014 - 9:56 AM - hans Comment Link

      I’ve been digging for a solution for this request – after all, it would be great to save the minimal needed amount of data. Not just so it fits on a different size SD-card but also to save disk space when storing it somewhere for later use.

      When I looked for a solution to minimize the size of a partition (ext2/3/4), then the first problem we’d run into is that MacOS X does not support any of these filesystems. So resizing requires either Linux or a filesystem “driver” for any of the ext formats (there are a few out there like MacFuse and Paragon ExtFS), which is not something I can assume a user to have on their Mac.
      So for now I do not see a universal solution for this.

      I’ll keep looking for options where not the entire SD-Card is being used (ie. the sum of the partition is not equal to the capacity of the SD-Card).



      • May 8, 2014 - 9:19 AM - Thorin Pham - Author: Comment Link

        MacFuse or Paragon ExtFS could be a temporary option for those who want to save the minimal needed amount of data. Thank you for your works to community, Hans!

  • May 9, 2014 - 12:00 PM - William Stephenson - Author: Comment Link

    I got a chance to put your ApplePi-Baker to work the past few days and it worked great. For me, it is a lot faster than using PiWriter and PiCloner. Those have worked for a long time so I was glad to have them,  but ApplePi-Baker is much faster. 

    There are two feature requests I’ll offer. One is to reduce the disk image size. The other is to compress the image. I’ve been doing both of these with the Pi lately.  PiCloner does this on the Mac, so it can be done, but it’s easy to do on the pi and there’s a perl script that runs on the Pi to reduce the image size, so I do those both there. I know the script calls some linux tools to do this (gparted?) so it doesn’t run on the Mac, but perhaps that can be worked around. There’s a thread on the Pi forums for this script here:

    Those would be nice, but mostly I came to say “Thank You”. You’ve crafted a really cool toolset here and I do appreciate the work you’ve done. 


    William Stephenson

    • May 9, 2014 - 12:24 PM - hans Comment Link

      Thank you William for the kind words – it’s very much appreciated.

      I guess compressing an image would not be too hard to implement – so I’ll add it to the “To do” list .

      Reducing disk image size might be little trickier, but I’m very interested in this myself. GPartEd is indeed only for Linux. I’d rather build something that doesn’t require any special tools (unless I can include the binary in the ApplePi-Baker package). I think the main issue is the filesystem used by the Raspberry Pi images … MacOS X doesn’t support most of them (EXT2,3,4), so that adds an extra complication. I’m keeping my eyes open though.

      Thanks for the suggestions! 



  • May 24, 2014 - 9:42 AM - Zumo - Author: Comment Link

    Hi Hans, many thanks also from me for this nifty little tool! As William stated before, image-compression would be highly appreciated.

    Another suggestion is to support usb-stick installations (eg. Raspbmc) with no FAT32 partition – as these usb-drive are not shown up in the finder (because of it’s only ext-partition), they also do not show up in the Apple-Pi Baker. Maybe you can manage to recognize these drives as well… the dd command does work, but it is awfully slow and has no progression bar ;)

    Many thanks again and best regards, Zumo.

    PS: As Mike from the first post, I was also not able to write into the text-field with Firefox, I had to switch to Safari.



    • May 25, 2014 - 7:45 AM - hans Comment Link

      Hi Zumo,

      thanks for the positive feedback. 

      I’ll add image compression to the “to do” list, and maybe I can add a checkbox to show “all” drives instead of only the SD cards, for advanced users.

      Thanks also for the FireFox note – I’ll have to check that out, since it used to work

      Give version 1.5 a try 



  • May 25, 2014 - 11:35 AM - hans Comment Link

    Just release v1.5 …

    This new release allows ZIP compression of the IMG file after creating a backup.

    This release will now also recognize USB sticks or SD-Cards that are not formatted in a format recognized by your Mac – for example ext3 or ext4, and will be able to make a backup of that as well.

      Hi Hans, thank you very much for this quick release of version 1.5! The ext3 formated USB stick is recognized and backed up flawlessly. Also the zipping works, but it is a little bit awkward to see the app with the rainbow-ball as frozen. Maybe in a further release a progress-bar will be added? ;)

      It’s so nice to get rid of the dd command :)



    • May 26, 2014 - 1:16 PM - hans Comment Link

      You’re welcome Zumo! 

      Glad to hear it all works as expected!
      Yeah the beach ball is not a great way to show “progress” … I’ll have to look into a way of tracking progress, but that would have taken much more time. It’s on the “todo” list  …

      v.1.5.1 released today … this minor version adds a progress bar to v1.5 when zipping a backup of a SD-Card or USB drive.

        Hello Hans,

        The backup file compressing feature is really useful. It helps me save a ton of my SSD space. How about the feature of writing image to SD card without decompressing the backup file? It means we can choose the .ZIP file  along with the .IMG file when writing image to SD card. So far, I have to unzip manually before choose IMG file.

          Hi Thorin,

          I was thinking the exact same thing, however …

          Internally I use “dd” and “zip”.

          For making a backup I had the idea to pipe dd output straight to zip, or
          for doing a restore pipe the zip output straight to dd.

          From the command line this works, however … I’d loose the ability to track progress 

          When using an internal ZIP option, the zip and unzip time increases dramatically (app. 400%), so I don’t consider that an option either …

          I’m still looking into this though …

    Thanks so much for this tool, very awesome and easy to use.

    Would love to see an option to Backup using rsync so I can backup incrementally when changes are made. This would also allow me to have a local copy that I could put into a repo to monitor and fork changes for development and testing.

    Not sure if it’s possible, but it’s a bit past my terminal abilities to achieve on my own.

    Regardless, keep up the great work!

      Hi Kray – seems your comment accidentally ended up in spam, so I reposted it.

      Thank you for the compliments and the suggestion. I’ll read the article you linked to and see what I can do with that. Seems to me though that this would require an OS that can read ext3/ext4 filesystems and the Mac (natively) cannot do this. Doesn’t mean I won’t explore it though  … would love to find alternative methods, for example only the files and not the entire disk (such a waste of space).

      Right now I’m working on a new version that allows Zip, 7z and GZip to be used for backup and restore, all in one move.



      • Jun 20, 2014 - 2:28 PM - Kray Mitchell Comment Link

        No problem! This raunchy solution looks ideal, though again, above my terminal comfort level lol.

        As OSX is Linux based, wouldn’t it be able to support that?

        Not very in depth at file systems either, so… Lol.

        Was also thinking about using Parallels to setup a Debian OS on to deal with stuff like this.

        Thanks again for the awesome tool. Do you accept paypal donations?

      • Jun 20, 2014 - 2:38 PM - hans Comment Link

        Hi Kray!

        I think MacOSX is FreeBSD based “to be precise” haha … anyhow, nope it does not support any of the EXT filesystems 

        I am however considering making a Linux version of ApplePi-Baker, just not quite sure yet how far I want both version to be different. Maybe later I’ll toy with some additional filesystems through FUSE and such, but I kind-a hate to have tell users to install this, that and the other thing. I really prefer single package solutions … but I will look into the options … 

        PayPal donations: Yes I do. Not sure if this PayPal link works but otherwise there is a button in the upper left corner of this page.
        Thank you for asking! 

        p.s. I use the latest versions of both VMWare Fusion and Parallels. I suspect Parallels might be tad faster (startup/shutdown) but has this annoying habit of “integrating” into my Mac environment when I use Coherence … it’s even so bad that files which I usually open with an existing Mac Application, by double clicking, are not automatically opening with a Windows application. There seems no way to disable this “feature” unless you’re not using coherence. Probably the last version of Parallels that I will purchase …

          Thanks Hans,

          I don’t mind installing extras for certain features if needed. I was actually thinking about purchasing ExtFS ( to ‘bridge the gap’ as they say LOL. My buddy knows more about Linux than me, so was going to have him check it out.

          Never had that issue with Parallels, but I also don’t use it heavily. I did some of my own tests for VM vs P and I found that Parallels just ran faster all the way around for me. Mostly web testing stuff though, so again, no heavy use.

          Totally missed the link at the top LOL thanks!

          thank you for your very generous donation …  You’ve made my day!

          I’m toying with an idea that could potentially shrink images significantly, but that’s when ApplePi-Baker hits v2 – I just finished compression and decompression on the fly, which I’m testing right now (supports ZIP, 7Zip, GZip) and seems to work very well. I hope to release that version either today or tomorrow.

          After that I’ll be working on my idea, which will be a much more complex to build and test, but I’ll keep you posted!

    Released today: Version 1.6.

    This version allows reading/writing of ZIP, 7Zip and GZ(ip) files, even the ones not created by ApplePi-Baker.

    In this version an “Abort” button has been added and the Authentication method has changed (needed SUDO access for compression).

      Hi Hans,

      1. Password Visible choice should be saved next time you open the app. 

      2. This screenshot is showing how the app layout on the whole screen of my Macbook after submit (press OK) password. Look at the right side. It should be centered or somewhere that the app windows can show entirely.

      3. When press Cancel on Admin password panel, I’m supposed that it should be quit the app immediately instead of asking 2 times (showing 2 alert windows after that) and opening the app. 

      Still not testing the feature of reading/writing of ZIP, 7Zip and GZ(ip) files yet.

      Thanks Hans for continuously updating

    • Jun 26, 2014 - 3:10 PM - hans Comment Link

      Hi Thorin,

      thank you very much for the very quick feedback – it’s much appreciated!

      1. Saving a root/sudo password is considered bad practice and frowned upon.
      But I’ll consider adding a checkbox, something like “Save for next time”, so users can check this if they are comfortable with that.

      2. Screen position: Thanks for the screenshot, I agree, the app should have been centered in the screen. Right now it let’s your Mac decide, but I’ll definitly change that in the next (minor) update.

      3. Quitting the app after clicking the Cancel button is what I originally had, but wasn’t quite sure how happy people would be with that. I’ll add it to the next update.

      Please let us know how Zip etc works for you.
      I’ve found that 7Zip is the most efficient format and performs actually pretty good. GZip and Zip perform OK, but compared to 7Zip I’d even call it “poor”. 7Zip seems to compress a lot better.

    Where’s version 1.6? No matter what they say, all the download links — both on the ApplePi-Baker Update page AND the Downloads page itself — are downloading the same file for Mac OS X. Which is “v0.1″ dated January 13, 2014. I cannot for the LIFE of me find a download link that actually gets me v1.6. Any help would be appreciated.

      Hi Ken,

      I’m sorry to hear you’re experiencing download issues.
      I’m not sure what is going wrong though …? 

      I just clicked the first link, to verify, but this correctly downloads v1.6 (this is the same link, filename “”).  

      Maybe your browser or proxy (work, school?) has cached an old version?
      Can you try another browser or another Internet connection?



      • Jul 7, 2014 - 8:35 AM - Kray Mitchell Comment Link

        I can also confirm this. 
        While the app launches and says 1.6, viewing the app in the Applications folder shows the app at v0.1

        Also shows created date of Jan 13, 2014

        Showed this with version 1.3 and after I upgraded to 1.6 as well.

    I am not able to restore a previously made backup. The program gets stuck in the “Baking IMG recipe” process. 

    I am moving from a smaller SD (1gb) to a bigger one (32gb). The .zip file with the backup gives me a .cpgz when I try to unzip it via the builtin image archiver OSX Mavericks.

    Any suggestion on how to restore it?



    • Sep 9, 2014 - 5:42 AM - hans - Author: Comment Link

      Hi Niko,

      Did you create the .ZIP file with Apple-Pi Baker?
      Also note that with the latest Apple-Pi Baker, unzipping is no longer needed.

      Another “issue” with zip is that when a zip file is created from the standard input, that it will give it no name or a weird name. Unzipping that afterwards will result in some weird filenames.

      Is this “hanging” happening with other SD cards as well?
      And is it happening with other images as well?

      Silly, I know, but make sure the SD-Card is unlocked (happens to me every now and then when I insert an SD card that the side of the slot hits the little “lock” slider and effectively sets the card to read only)?

    • Oct 4, 2014 - 2:48 AM - hans - Author: Comment Link

      Hi H Nolan,

      I’m not sure if this would work, but it’s worth a try:

      - Create a script which uses “dd” to create an image file of the SD
      - Store the image file directly on a network share
      - Add the script to your Cron

      You’d need a SMB of NFS mounted on each of the Pi’s. You do not want to write the “dd” output to the SD card obviously since “dd” is reading the disk when creating an image.

      My experience with Linux is a little limited so no guarantees that this will be 100% working, but worth a try.

      Once you have one Pi running this way, then it’s just a matter of copying the script to all the 125 Pi’s (That’s a LOT of Pi’s!) …

    I’m having issues with the SUDO password entry – installed the latest version of the software, input my password, even with it set to be visible, and I am 100% sure it is correct, and it is saying ‘Incorrect password”. Definitely the right password, and I’m definitely an admin account. Any ideas?



    • Oct 7, 2014 - 2:41 AM - hans - Author: Comment Link

      The password is used directly in SUDO shell statements. Maybe you’d like to try opening the Terminal and test something like:

      sudo ls

      Which should ask the password and show a file listing when entered correctly.

      What might also cause issues is passwords with unusual characters (like quotes, space, ampersand etc).

      As you might have read: the current password request method is far from what I like (hence the reference to the previous version). I’ll need to make some more time to revamp that part, as soon as I can find some time to do so …

      I’ve considered adding a price tag, but I want to keep it fun for myself as well. Adding a price tag makes me feel obligated to update and modify based on user requests which kind-a takes the fun out of it. But maybe one day I’ll add a tiny price tag since donations are rare …

      Hi llancit,

      Every Mac has a password.
      However, some Mac’s are setup to automatically login.

      During the setup process of your Mac you had to provide a password for this, this is always the case, and this is the password needed for ApplePi-Baker.
