Here's how to reproduce this:
- Installed VLC via:
brew cask install vlc*
- Open VLC (via Spotlight/Finder/
open/something else using launchd**)
- Finder alert dialog pops up with message:
The application “VLC.app” can’t be opened.
This has never been a problem until I installed the latest version. I'm guessing it's more something to do with launchd than VLC (my other MacBooks are all fine).
How can I diagnose what's failed and/or make this app launch again?
* makes no difference downloading with browser).
** I'm able to start it via:
$ /Applications/VLC.app/Contents/MacOS/VLC, so I am guessing it's something to do with what is launching it.
