Re: If sims 4 legacy edition d why do I have to update my sims?

@smcaaz  The Legacy Edition does not get updates, unfortunately.  So even though the game files are being patched, there's no practical effect on gameplay in the LE.  That means no platforms or anything else that didn't exist in Sims 4 a year ago.

Just to clarify, your Mac and its operating system are 64-bit.  Sims 4 is and has always been 64-bit in macOS, just not in Windows.  The issue with older Macs like yours is that they don't support Metal, which is a graphics API that the standard version of Sims 4 now uses rather than the older OpenGL.
