crashes every session.

I have a hard time playing this game because every time I do its always a matter of time before it crashes & I loose all progress. I even stopped playing it for months but then played it again today and after 2 hours BAM! CRASH! I shold get a refund as I never once had a single problem on Windows opperation but nothing but limitations and crashing on MacBook Air early 2015 & fully updated. These problems existed from day one. So sad because its my all time favorite computer game.
