Question Counter Strike:GO won't run on 2010 Mac Pro

[MotionMan]

I just acquired a Mac Pro (Mid 2010), 2 x 3.46 GHz 6-Core Xeons, 32 GB 1333 MHz RAM, 250 GB SSD, 1 TB HD, NVIDIA GeForce GTX 980 Ti 6144 MB.

I did a full format and reinstall of the OS on the SSD and am currently running High Sierra (10.13.6) (though I initially tried using a dosdude1 patched version of Catalina (10.15.4), with the same crappy result, so I reformatted again to install a fresh and clean copy of High Sierra).

The first (only) thing I installed after the OS was Steam and Counter Strike:GO. However, when I try to run CS:GO, I get the following message:

"Error. This game requires OS X version 10.6.7 or higher."
(It looks just like this.)

I Googled that error and found very few results, and none with an answer.

I am not sure if it is related, but I seem to be getting a lot of flicker in the Steam window, too.

I reached out to the person I got it from and she said she did not have any problems with it before I got it.

Any ideas? Thanks.

shouldn't you be playing Valorant instead?

Problem solved.

It was a driver issue.

Thanks.

CS:GO is written like redacted for Mac.

I don’t really know how it runs well for your friend. Newer ones can handle it better with brute force, but they still suffer from strange redacted happening

Hi motionman!

Would you happen to know what driver solved this issue? I am having the SAME exact problem you had when trying to open steam games such as CS:GO and cannot find a solution.
