Hi,
As I want a clean system, I conducted a series of extra tests to understand why the "delete picture version" did not work.
I can now say that it was related to this second volume (disk) I added in my laptop, which had, for an unknown reason, a permissions issue.
Note that it's impossible to automatically check the volume permissions on a non-bootable partition!
The impact of this permission problem is that the Trash is not working on this volume.
I'm sorry that Aperture didn't mention this (delete) error anywhere during my troubleshooting, as it could have saved me a lot of time!
So here's how to detect and fix:
- Create a folder or file next to your library on this volume, then try to delete this empty folder/file.
- At this time, it won't be moved to the Trash, but Finder proposes to delete it directly. Don't.
- First open this other disk volume with Finder using the "Get Info" (CMD-I) and go at the bottom of the window.
- Enable the option "Ignore ownership on this volume" (your password may be needed to unlock this feature first).
- Check if the Trash is now working by deleting this empty folder/file. If you did the right operation, it should be placed in the Trash.
Now the permission issue is fixed, try again to delete your pictures from Aperture, and they will be moved automatically to the Trash.
Cheers
