Hi everyone, I have a problem as the following: Every time I reboot the Mac, the Mission Control loses its layout: only 1 desktop remaining and all the windows of applications are on that desktop. It's MacBook Pro 2016 15" and OS X 10.12.3. I used the Time Machine to recover my personal files when I got the new MacBook Pro. I tried to open another brand new admin account without any personal files, and there is no such problem for that account. It proves that it's not hardware problem. I think some personal files somehow affects the system. Any help or suggestions would be appreciated!
