You could also try opening the game in windowed mode - Right click on the Options.ini file in Documents > Electronic Arts > The Sims 4 and choose TextEdit to open it with. Once opened, where it says fullscreen = 1, change the 1 to 0. Save if prompted.
I tried this as well, and also putting the Options file in the trash but it still happens.
Really appreciate your help so far - any other suggestions?
Did you cleanly install on your Mac's HD and start a brand new game? With nothing added from the install on the external drive?
Is your MBA a 2015 model?
Yeh I fully uninstalled and reinstalled the game.
My MBA is 2013 not 2015. is that an issue?
Cheers
It may be depending on the full specs. Please can you provide more information about your Mac? Instructions on how to do so here - http://answers.ea.com/t5/The-Sims-Mac/READ-FIRST-Sims-4-Mac-Help-Guides-and-Troubleshooting/m-p/4612396/highlight/true#M162
