[HELP] Getting black screen on Mac versions of certain Steam games

Hello. I currently have a Hackintosh in order to test some games in Mac. This is in order to test if the fan-made Spanish translations of these games work here. The games I mentioned are the "Jackbox" games.

So far, after I installed a Hackintosh using VMWare, the same thing happens every time I open a game: a gray/black screen. Although sound plays and I can press Enter to continue, since nothing is displayed obviously I can't test anything.

So far I tried versions 10.12, 10.14 and 11.0.1. The only one that had a substancial difference was 10.12. While a gray screen still happened, if I moved the window a little bit the screen would render a frame of what's happening in the game.

I also tried another game (Crawl) to see if every game was affected, and that wasn't the case. The game opened and was totally playable. So I really don't know what's going on here. In case it helps, the Jackbox games run in Flash, as the games use "swf" files to render their graphics.

Did anyone else have this problem? Doubt it since I don't know who would play these games on a Hackintosh but maybe something similar happened to another game. Thanks.

My specs:

Laptop (I mainly test here):

Intel Core I5-400U - 12GB of RAM - NVIDIA GeForce 940MX

Main computer:

Intel Core

Intel Core I5-10400f - 8GB of RAM - NVIDIA GeForce 1070
