please help as ive been trying to download the sims for a couple of days now and i just wanna play the sims

You won't ever get it to run under MacOS, because it was never made to run natively on a Mac, the Windows version was simply emulated (extremely badly). You could Google 'Bluebell Flora's The Sims 3 MacOS Installation Guide' and see if that helps (this is my first post, so I can't post links yet) but I never could get it to run, so I bought Parallels and installed Windows 10. 

To all intents and purposes The Sims 3 is a Windows-only game.

There is also a guide stickied under "Mac OS Tutorials" here:

Though I can't really say much more beyond that, as I don't know much about Macs.
