'The application "DiskImageMounter.app" can't be opened.' - Sierra 10.12.2

I have always been able to look into the Time Machine backups on my Time Capsules. I just upgraded my first system to Sierra (10.12.2) from El Capitan (10.11.6). Now when I try to open the sparse bundles on the Time Capsule I get 'The application "DiskImageMounter.app" can't be opened.' with a code of -35.

I find the same sparse bundles on the Time Capsules do still open OK from El Capitan, and I am still able to open sparse bundles on directly connected hard drives in Sierra.

I verified all this on two Macs using virgin installs of both versions of the OS.

Is something broken? I got some pushback from Apple Support about the only supported way to interact with the backup files is through the Enter Time Machine option in Time Machine. Opening the files via Finder has been something that has worked for many years. I am wondering if they either accidentally, or perhaps intentionally disabled the ability to open those files - he talked about people doing it causing a lot of trouble.

MacBook Pro with Retina display, macOS Sierra (10.12.2), null

I have the same problem: with OS 10.12.2 I cannot access the backups of the three systems connected to the same Airport capsule 7.7.8. I read DiskimageMounter not available (-36).

Test with the third party application "Auto Mounter" https://itunes.apple.com/us/app/automounter/id1160435653?mt=12

I seem to have solved the problem temporarily.

SMB did not help me because it is 50% slower than for AFP when copying large amounts of data. Or files that weigh more than 4GB.

Now you can try using the shortcut directly without buying the application.

Cmd+K afp://name time capsule.local/name internal disk

in my case.. afp://Time-Capsule.local/AirPort Disk

Right. Is it really -36? I thought I saw -35. Not that it matters - when I called AppleCare they did not have a clue in any case.

Upon further review 🙂 I see that yes, the error code is indeed -36, not -35.

This worked for me. Was receiving same error (-36) when trying to connect. Used Disk Utility, and able to mount drive and access files just fine.

I also get the -36 error today. I believe it was as recently as 2 weeks ago that this was working for me.

I am assuming the update to 10.12.2 is what borked it.

Yes, it looks like it came in the 10.12.2 update around that time. Check if/when you made that update vs when the problem started for you.

I've seen this reported on other lists and it seems to be a bug in 10.12.2.
