I have noticed a bug in Mission Control on macOS Sierra (10.12.2).

Here's a GIF to reproduce the bug:

enter image description here

It happens when I try to open an app from the Dock, while I'm showing the Desktop: the app doesn't open, windows come back in place, then if I toggle Mission Control, the app I clicked before opens (or get in front if already opened).

Step by step, as shown in GIF:

  1. Show Desktop

  2. Click on any app in the Dock

  3. App won't open, windows come back in place instead

  4. Open Mission control

  5. Exit Mission control: previously clicked app opens

Is anyone experiencing the same?

I was able to replicate the bug with your instructions. (mid-2014 rMBP, macOS 10.12.2) I would recommend that you report it to Apple to alert them of the bug.

  • Thanks, I already reported it to Apple. I also started another discussion on their official support forum, where other users confirmed the same behavior: discussions.apple.com/message/31173836 – countfak Dec 30 '16 at 8:54
  • This is fixed on Sierra 10.12.4 – countfak Apr 9 '17 at 11:26
