I use TS extensively, but upon upgrading to Sierra, having Terminal on one Space and Safari on another is problematic:
One Space only has Terminal
One Space only has Safari
Switch to Terminal Space, type in Terminal, switch back to Safari’s Space with hotkey
Terminal is still focused
Old behavior is that Safari would be focused. This behavior DOES still work with most apps, like Spotify and Slack: any Space with a set of apps that don’t match the app previously in focus results in one of the apps on the new Space being in focus, which is proper. Just not with Terminal->Safari switching. The opposite, Safari->Terminal, does work correctly.
Will do tonight. Interesting update: I can’t do it right now, since the MBA 13" doesn’t have the same problem using 2.3.5 or 2.4.6 (autoupdated). This laptop doesn’t have integrated + discrete graphics like the MBP that has this issue.
