PrintVault Desktop v0.2.23
Open in slicer finally works on macOS, and you can delete a whole model.
Open in slicer
Picking any application on macOS gave "Permission denied (os error 13)", which reads like a sandbox or code signing problem and is neither. A macOS application is a bundle, which is a directory rather than something you can execute, so running it directly fails. Application bundles go through Launch Services now, while a plain command line binary still runs directly.
Found, diagnosed and tested on real hardware by @howardaron-git, who also sent the fix. macOS is the platform I cannot test, so this sat there quietly until somebody who could actually run it went looking. See #3.
Deleting a model
Removing a model meant opening it and deleting each file one at a time, which for a forty file pack is not really a feature. There is a Delete on the model now that takes the lot.
It follows the duplicate cleanup rather than the single file delete, so by default it moves everything to the quarantine folder instead of destroying it, and tells you how many files and how much space before you commit. The emptied folder is removed too, but only if it is genuinely empty.
