I checked and I’m pretty positive I do have the 64 bit
@hbs1121 The question for Macs is not whether they run a 64-bit OS (they do, and they have for more than a decade), it's whether a particular Mac supports Metal. Those that don't cannot run the standard version of Sims 4 and are stuck with the Legacy Edition. If you're not sure whether your Mac's hardware supports Metal, please list its specs here, as described in this post:
The other problem is your OS: Yosemite doesn't support Metal. But if necessary, you can update to El Capitan or later.
