Mounting SMB share failes with "NetFSMountURL: Error - Internal error"

I've just "upgraded" my Mac to macOS Tahoe 26.4 (from 26.3, where ConnectMeNow 4.0.18 worked without issues). Since that "upgrade", ConnectMeNow fails to mount any of my Samba shares from my local Windows 10 PC. Sometimes I see a notification saying that a mount attempt failed; more often the attempt fails with no error or warning notification of any kind.

I can mount the same network shares using the built-in support in Finder or using the mount command in Terminal, so there isn't a network issue or a problem with the share configuration; it's just ConnectMeNow that doesn't work.

I've upgraded to ConnectMeNow 4.0.19 beta to see whether it fixes the problem, and it doesn't. Looking for additional suggestions about how I can debug and correct this problem.


Version: 4.0.19 (Build 82)
OS: macOS Tahoe 26
Version 26.4 (Build 25E246)
ARM (64 bits) application


Debug log extract:

The "NetFSMountURL: Error - Internal error" message seems as though it's preventing the Mac from finding the matching network share.

I'll have to "upgrade" my Mac to Tahoe 26.4 first to do some testing.
Will reply later this afternoon 😊 

Note: I thought Windows doesn't like it that one mounts without login credentials? Since you mentioned that all worked will with Tahoe 26.3, I'll assume I'm recalling that wrong.

Just upgraded to 25.4 and ... ConnectMeNow mounts shares to my NAS just fine.

One thing though, a notification appeared asking me if ConnectMeNow is allowed to find devices in the local network.
Did you get this message, and if so: did you click allow?

If you missed it, you can find it under:

System Settings -> Privacy & Security -> Local Network -> ConnectMeNow4.app should be enabled.

Please let me know if this fixed the issue. 😊
