As I posted earlier, the Sims 4 will be coming to the Mac in February. While a firm release date still hasn't been given, Maxis has released the minimum specs you will need to run the Sims 4 on a Mac:
Macintosh System Requirements for The Sims 4
MINIMUM OS: Mac OS® X 10.7.5 (Lion) CPU: Intel Core 2 Duo 2.4GHz Processor or better

Additionally, if you already own a version of the Sims 4 for PC, you will automatically get it for Mac. Finally, all future content should be released for both systems concurrently.
