Can anyone tell me if they are having this issue? Very annoying issue that just popped up for me in 10.11.1 I have copied and pasted this from a bug report I just submitted today - When using Cmd+Tab or the Dock to switch between apps (non-fullscreen): If apps are in the same desktop this works correctly. When using Cmd+Tab or the Dock switch from app (non-fullscreen): If apps are in different desktop, this does not work correctly. The menubar changes to the new app (the menu bar changes in the current desktop), however the app itself is NOT brought to the foreground as the desktop is not switched. Any keyboard shortcuts performed here with the menu bar selected are not honoured in the app, and get alert tone. When using Cmd+Tab or the Dock to switch apps (full-screen): If changing between two fullscreen apps, focus works perfectly. If changing from a full-screen app to non-fullscreen app, this does change desktop as expected and the menu bar for the app is visible however the same issue occurs - no app focus (with cursor etc). NOTE: When using Mission Control (four finger swipe) or via a hot corner, the correct app focus works all the time - this issue is only isolated to Cmd+Tab or app switching via the Dock.
