ApplePi-Baker v2.2.0 release for Catalina

ApplePi-Baker v2.2.0 release for Catalina

We have just released ApplePi-Baker v2.2.0.
This version was released with macOS Catalina in mind.

The first release of macOS Catalina (10.15) came with some serious problems for applications like ApplePi-Baker and the likes (Etcher etc).
The “Full Disk Access” security setting seemed to have a bug, preventing reliable access to external disks.

After Apple released its first update (10.15.1) this bug seems to be resolved in a way.
Accessing external disks still comes with a few challenges, so when a disk is being selected, ApplePi-Baker will verify  if “Full Disk Access” works.
If not, a notification and explanation will be shown how to enable “Full Disk Access” for ApplePi-Baker.

Additionally, a small bug (leaving a temp file behind after a backup or restore in ~/tmp) has been resolved.
If partition resizing was used when restoring an image, the resized IMG will still remain, saving you the time to restore the same image again.

    1.9.9 works with Catalina. Version 2 and above doesn’t. Tells you that you need to grant full disk permissions and even after you do, it still doesn’t work.

      Hi David!

      I’m sorry to hear you’re running into issue.

      It seems that a handful of users experience this issue.
      I’m trying to debug this, but cannot reproduce this issue on the 4 Mac’s that I have access to (MBP 13″ 2013, MBP 15″ 2017, MB 12″ and a Mac Pro 2013).
      I’ve been testing with one of the users in the past few days, if you’d like you can try the test version as well. You can download it here.

      Without users helping me with testing, this will be very difficult to fix … so any help/testing is appreciated.

      In case you prefer to discuss testing by email, feel free to email me at webmaster at tweaking4all dot com.
      Please do mention the context (I do get a lot of emails on any given day, concerning several projects I’m working on).

        Please try the beta release (2.2.5 build 22) …

        I cannot guarantee this beta to resolve the issue though.
        What kind of message do you get when it crashes?
        p.s. do not post full reports from your Mac here. Consider using the forum for that if needed.

      Hi Uri Pierre Noel,

      Theoretically any version should work. I’d recommend starting with the current release version of V2 (here).
      If you run into issues, you can give the v2 Beta a try (here).
      If you keep running into issue (please report, maybe I can help) consider using the older v1.99 (here).

      Note: ApplePi-Baker wasn’t really designed for this purpose and doesn’t change anything when it comes to ISO files or IMG files. This means you system must be able to handle said format to boot from (in my experience this is quite often the case – I haven’t ran into a failure yet).

      Please let us know if it worked and what Linux image you sued. Would be nice for others to see if it works or not.

    I cannot get this tool to work on my M1 MacBook Pro running Ventura 13.5. 

    I had that common error issue on app startup, but granted Full Disk Access to the app, restarted my Mac, and now the app starts normally. 

    My issue now is that when select a disk, and then select an image to Restore, I get “ERROR – Unable to open destination /dev/disk6”. 

    Usually that’s it, but one time I also got the pop-up that I need to enable Full Disk Access. The problem is that I double-checked and that was already done. 

    I do not see any place to enable it for the helper app. Is that the issue? How would I do that. I don’t know where to find it.

      Since you do not mention the ApplePiBaker version, try the beta version (2.3.0) which seems to make a difference.

      I’ve been using it on Ventura 13.4 on my M1 MacBook Pro as well – zero issues.
      Upgraded to 13.5 just now, fully remove ApplePi-Baker (helper tool included) before the upgrade, and re-downloaded the beta – just to make sure.

      Note: in both Ventura versions, ApplePi-Baker is listed under “Full Disk Access”. But not the helper tool.

      If you’d like to add the Helper tool as well, although it should not make a difference since this is already a “privileged” helper tool, you can find the binary here: 


      Again; to the best of my knowledge, this should not make a difference.
      You could try deleting the helper tool, rebooting and firing up ApplePi-Baker again.


      Assumptions I’ve made:
      – you’ve placed ApplePi-Baker in your Applications folder (eg not started from the DMG or any other location).
      – you’re the admin user (typically scenario which each Mac, especially when bought privately and used by one user).

      I hope any of this helps.

    Aha… the beta version does seem to work for me. Thank you!! 

    It did take two tries. On the first go, I got the “disk is not readable by this computer” pop-up and chose “Eject”, but the app was stuck at 98% complete. I had to force quit it. I erased the microSD card and tried the exact same thing again. This time it got to “complete” and seemed to work fine (still “unreadable” and choosing eject, but not stuck at 98%.)

    Again, thanks!

      Hi Rich,

      Good to hear that! 

      And my apologies again for the inconvenience – I really wish I knew why this happens with a handful of users.
      I just cannot reproduce the issue, on any of my Macs and Macs of some of my testers (both Intel, M1, and M2) even though I really would love to know why this happens 

      Glad it works now though! Have a good weekend! 

      (p.s. I’m assuming you can actually use APB now and the “unreadable” disk is expected behavior?)

        If it helps perhaps duplicate the issue, here is more info about my situation: 

        MacBook Pro, 14-inch, 2021 with M1 Pro chip

        macOS Ventura 13.5

        2 GB SanDisk microSD card, in SanDisk microSDXC SD adapter, in MacBook’s built-in SD card reader

        “restoring” to this disk image, which is firmware for my 3D printer:

        Also connected are a 2 TB Crucial external SSD and a 27-inch LG monitor (designed for Mac with built-in webcam and speakers, so it’s like several different USB devices connected.)

        And I use Backblaze for cloud backup, which I mention because it also has the full disk access permission, so perhaps there’s some kind of conflict there? 



      • Aug 13, 2023 - 11:12 AM - Hans - Author: Comment Link

        Thanks for sharing Rich – Nice setup! 

        It’s very much appreciated! How much memory does your Mac have?
        Good that you mention tools/services like Backblaze – but I haven’t heard of any conflicts with tools like that.
        What -could- happen of course is when a tools somehow accesses your SD card while APB is read/writing to it (even though APB requests exclusive access from macOS).
        I’m thinking virus scanners, or cleaners like Blueharvest (this one does not interfere with APB at all).

        I honestly think it’s somehow an issue with Gatekeeper maybe – not the first time goofy things happen with these new features.

          I have 32 GB of RAM. 

          I do not have a virus scanner nor “cleaner” software. 



        • Aug 14, 2023 - 10:33 AM - Hans - Author: Comment Link

          Seems your setup is comparable to mine then. Also 32Gb RAM, M1 Max Macbook Pro (16″).
          Not running antivirus, but am running Blue Harvest to keep my network and external drives clean (eg. those little Apple files).
