EA are you updating simcity to 64 bit for Mac?

Hi @PBL84 - There is no way to know if or when EA will make a definitive announcement either way. They have announced some of their 32-bit games being updated to 64-bit, and others, like SimCity have had no announcement. 

See This Thread for more information and some options if you wish to run SimCity after upgrading to Catalina. You may wish to subscribe to that thread, because if there is an announcement made or more information becomes available, I will update that post. If you recently purchased SimCity and found you can't play it, you may be able to take advantage of the Great Game Guarantee.

Wish I had better news for you, but that's all the information any of us has at this point.
