*NEW* patch (49.2) crashes and more on Mac (NOT catalina, Im on Mojave)

I have not yet updated to catalina as I tend to wait till the last second. this newest patch from 1/22/20 has made the game unplayable. First off, in fullscreen, if I play in a resolution lower than my monitor (5120x1080) i can only pan my mouse around what that area would look like if it were windowed. To fix that you have to alt tab out then back in- and that also occurs when in windowed modes. Once you get that part working you have to deal with stuttering and freezing and the occasional yellow screen. Im used to playing on “ultra” settings, 1440/fullscreen. but I tried going down to “good” at 1080 and it was just as bad. Its kicked me out of games and crashed and its not just sky temple like the other posts. I have a big white square in the middle of the screen for brawl mode :(.

system:
iMac (Retina 5K, 27-inch, 2017)
3.5 GHz Intel Core i5
24 GB 2400 MHz DDR4
Radeon Pro 575 4 GB

Please help. And for what its worth I can still play just fine on my pc but like…meh, Id rather. not run both computers :confused:

Crashing on macOS Sierra as well.
