Civ 5 keeps crashing on my Mac

[diesel_fox9]

The game keeps crashing at the same time. I try and play my turn, then it crashes and exits out of the game. I can't even move forward in the game, it crashes on my first turn that I've taken since playing. I have a macbook pro 15 inch, Mid 2015. Version 10.15.1.

I was using Mojave and the game was crashing, so I thought maybe I needed to update to Catalina. So I just updated to Catalina, but it still was crashing. Any suggestions on how to fix this?

I have the same issue. I just updated to Catalina and the game won't start anymore. What to do?

Civ used to be very stable for me, now is crashes 'reliably' in the late game (ex. turn 340). Restarting just repeats the problem. Reboot, uninstall/reinstall - same issue. Updated Steam client again - same issue. I wonder if this is an issue with the recent Steam client update. My machine is a Mac Air (11", 2015, i7) running Mac OS 10.13.6 (High Sierra).

I currently have to keep reinstalling my game (under Mojave) to keep it somewhat stable, so something is degenerating over time. Ends up crashing after the loading screen after approx a couple of plays. Still crashes occasionally on stuff like religious conversions.
Wish there was a way to revert this entire 64-bit disaster, I'm not getting Catalina anyway.

my game crashes too, I think it has to do with the upgrade, either Steam upgrade or upgrade to high sierra on my mac

Same issue here, tried reinstalling, closing other apps, setting up a separate partition, nothing seems to help. Only mod I have is EUI :-(
