All of a sudden some running applications were not shown on the ⌘+⇥ on-screen list. I had to restart my MBP, running Yosemite 10.10.2.
After restarting, ⌘+⇥ was not working any more (no app shown on screen, not even the Finder) and the Dock showed some non-running apps as running (with the circle). By clicking any 'running' app the circle disappeared.
So I opened Terminal and run
- The Dock did not restart.
- ⌘+⇥ is still not working.
- Restart does not work.
- Shut-down does not work.
- Spotlight works and I can launch apps.
No apps were installed between the normal, working stage and this absurd state.
What's the problem? Any suggestion?
