Sims 3 Mac Error Won't Start

I recently bought, downloaded, and installed Sims 3 for my Mac via Orgin. Here's my info:

Macbook Pro9,2 (13-inch, Mid 2012)

2.5 GHz Intel Core i5

16 GB 1600 MHz DDR3

Intel HD Graphics 4000 1536 MB

macOS High Sierra 10.13.2

After installing, I try opening and I get an "unknown error" that won't allow me to even open the game.

Here's what I tried:

I went into the info.plist and changed the S3Launcher.exe to TS3W.exe and it gave me this error:

"service initialization failed 0x0175dcbb"

I used the most recent patch- did nothing.

I've gone in to the graphicscard.sgr and graphicsrules.sgr and changed some things as this post says: https://bluebellflora.com/fix-for-incompatible-graphics-for-the-sims-3-on-mac/

but my mac wasn't on that list and none of the others worked.

I've reinstalled about 5 times now.

There's no cache data because I haven't been able to play.

Not sure what else to do? 

I'm real upset cause I just bought this game without knowing it had issues with macs.

Please help!!
