Valve have started offering refunds for CS:GO prime (not any of the microtransactions) if you played mostly on a Mac, or if you bought prime on a low-end Windows machine* between the CS2 beta and CS2 release https://help.steampowered.com/en/faqs/view/73EF-08A3-0935-6369
make sure to get your refunds in if you were affected!
this post also acts as the first true confirmation that macOS will likely never be supported for CS2. disappointing
