Macs running Apple Silicon CPUs have to use Rosetta 2 to play games like Civ VI, since they haven't been recompiled for the ARM64 infrastructure. I suspect that extra level of indirection can cause all sorts of problems...

I'm having the same issues of this not working on my mac.

Can you specify what kind of Mac you have?

Same issue, won't open

same problem with me, it says "This file was downloaded on an unknown date." below the error note “Civilization VI.app” is damaged and can’t be opened. You should move it to the Trash." Please fix it asap

BTW , I managed to work the game by chance. Used the control key while opening it from finder (first you need to browse the application file) and pressing control while opening the game (as a system admin) and it worked for me. After the first play, the other plays were as normal inside steam

SOLUTIION TO FIX an infinity loading screen:

Go to System settings -> Privacy & Security -> Full Disk Access -> select Civilization 6.

And do what? Full Disk Does not allow access and Civ 6 isn't an option

This solved my error - I've noticed most of the issues related to Mac are solved by either performing OS system update / Privacy & Security config updates to allow Civ app access.

I tried but it doesn't work

there is a new update. Once I updated, the game magically started to work again.

Hey, just wondering: are you running on an Apple Silicon Mac, or an Intel Mac?

“Civilization VI” is damaged and can’t be opened. You should move it to the Trash.

This file was downloaded on an unknown date.

Ever since I updated to MacOS Ventura 13.2, I get the above error whenever I try to open Civ 6. First, it'll have me update the game for like 8 minutes or so, then it'll give me the error message above when I try to open it. The game worked mostly fine before the update.

This is happening on my Mac Book Pro (Processor: 2.6 GHz 6-Core Intel Core i7).

Is this the only place to let the devs know how prevalent this issue is?

Well, drat. I was hoping this issue was only associated with Rosetta. :(

Actually, I doubt the devs spend too much time monitoring this discussion board (if at all). But Aspyr does have a website you can visit. In fact, it seems as though they are already aware of the issue, and are delaying further work on new material to concentrate on fixing the bugs:

Thanks for the helpful link. I guess I can rest easy know that they're aware of the issue, plus, I shouldn't even be playing Civ right now anyways lol. I'll keep an eye on their twitter. i guess.

Yes for me! Games start ok, but after 20 or 30 moves the streaks appear, and never go away for that game. Anyone know the cause of this?

Whilst not having a fix, from attempting to play the game I feel like I've at least found the graphical element that's the source of the issue. It occurs with Civ IV's 'fog of war' sepia effect, specifically the outline of the pine trees (woods or rainforest), where not being zoomed in super close causes them to sky-beam the dark outline instead of being contained around the shape. That's why it kicks in 20-30 turns in, because you've explored enough of the map to have some 'fog of war' areas.
