MacOS and anti-cheat

I play CSGO on a Mac and I want to play Faceit, but when I attempt to queue for 5 v 5 matchmaking I am told that I need to download the Faceit anti-cheat. I can’t download the anti-cheat because it is not compatible with the MacOS. I played Faceit matchmaking once before (when I first started playing CSGO) and I did not need the anti-cheat. I played very badly and my stats were terrible for that match, could this possibly be a reason why I’m required to download the anti-cheat.

I would greatly appreciate any help.
