@heyjudeysabel Origin has been acting up with mac downloads lately, although on High Sierra it's less likely that you'd be unable to fix the issue. Try running the Origin reset tool for macs:

If it works, please download only the base game. Then run the Super Patch (digital download version).

After that, if you try to launch (still just the base game), you'll get an unknown error message. But Bluebellflora—the mac hero here—has been kind enough to write up a pretty simple solution for players with your particular graphics card:

If you follow her instructions, you should be able to launch and play the base game. Then we can move on to installing packs, which will necessitate a couple of other interventions.
P.S. It's unnecessary to launch TS3 through Origin on a mac, or to even have it open while you play. You can just use the alias that you have in your Applications folder.
@puzzlezaddict @EA_Darko I did all of Bluebellflora's steps and at the end of it all, when I tried to launch the game, it still came up with the bubble 'error occurred'. ☹️
@heyjudeysabel There are additional steps you need to take to get certain packs to run in mac OS. Have you installed any packs, or are you still just stuck on the base game? And did you do a clean uninstall before starting the process? If not, it's possible that there are some leftover files in your library.
Regardless, it would be helpful if you could pinpoint exactly where you are in the install process.
@puzzlezaddict @EA_Darko I just finished fixing the Graphic Rules and Graphic Cards on the base game and tried to launch it, but it still said "unknown error occurred".
@heyjudeysabel There's a minor point, it might not apply to you, but it actually tripped me up when I was messing with my own .sgr files. In the lines you added, what do the quote marks look like? Are they identical to the ones in the lines of code that you didn't alter, or are they sort of slanted? If you're not sure, you can delete the new ones you added and just c/p quote marks from one of the unaltered lines. (That's what I did to fix it.)
One quick question: How much free storage do you have on your computer? You can check by clicking on the Apple icon/About This Mac/Storage. It would also be a good idea to restart your computer right before you try to launch, just to make sure there's nothing else running that could take up resources the game needs for itself.
If none of this works, then probably the only other thing to try is installing in a new user account. Do a clean uninstall, then create an admin account, login to it, and install, then patch, then repeat the .sgr files fix (or save your existing files and transfer them over), then try to launch. Your processor/graphics card combination is particularly difficult, and some people who have it can never get the game running. But this might work where the other attempts have failed.
