This issue now seems to be fixed in the 1.68.154.1220 November 2020 patch.
Thanks all for confirming it now seems to be fixed. If you start experiencing issues again please post 🙂
It's definitely not a full system crash for me. The closest I got to that was the Origin glitch if it froze in windowed mode instead of fullscreen; the game would close itself and the client would claim that it was logged in on another computer (it was not). The only thing I could do to fix it was restart the computer, but there was no LastCrash file. It doesn't really seem to be a "crash." About half the time, I can actually mouse through the exit menu by watching the cursor change shape, and if I'm in build mode and click on a menu item, I can hear the sound effect for selecting an item, for example. The game is responding, according to macOS; but the graphics are wrong.
I did disable Origin in-game, especially because of that weird Origin glitch, and it didn't help the overall game freeze. So far, the only thing that seems to have made a serious improvement was disabling f.lux.
I tend to be able to move the mouse even when the screen goes completely frozen, and still with the ingame pointer rather than the system one.
Yesterday I managed to play for several hours on a new save. Regular gameplay, on one of the premade lots. Made some minor build changes to it and added new furniture with no issue. I then made a new save for building, created a tester family, exited to manage worlds and went into a lot to build. Within twenty minutes it started freezing again.
Tonight I tested the linked fixes. iCloud is disabled already, I disabled retina display ingame, toggled laptop mode, enabled vertical sync, and reset my NVRAM. No change. The build lot now starts acting up within less than five minutes of opening it, some times less than a minute.
Have the same configuration and the same issue reported in the latest patch update.
I tested by running just Origin and the game with all other apps closed and still the same issue.
Tried everything listed in this thread and the Macbook 16" thread, nothing is working as of now. The game gets stuck every 15 minutes.
Even Big Sur update didn't help.
