XCOM 2 is crashing on Mac

[Der Chefkoch]

I had lots of fun playing XCOM 2 on my Mac from 2013, it was working actually quite well on this non-gaming laptop.

However, the more I advanced in the game the more unstable it got and crashing, now with the final mission being unplayable as it is constantly crashing.

I play with all DLCs without WotC. Any hints what it could be?

I could not post the full Mac Crashlog here, as it might be too long. Anything I should post here?

I was having this problem too running XCOM 2 with long war 2 on my Mac. I ended up reducing the resolution and going onto properties and disabling cloud saving (only using local file saves instead). This helped it run better and stopped me from crashing during the mission I was stuck on!

Do you use mods?

[Der Chefkoch]

Thanks for the replies!

SunDrippedDevil I had those problems without mods, so that wasnt the issue.

Dante I was taking the exact same measures on WotC now. Disabling Cloud Saving and reducing resolution did in fact improve things. However, it did not resolve the issue completely. On WotC especially the last mission started crashing so much it was not to be finished. Incidently I could finish the mission after a reinstall of the game and using the previous save.

Would you please share your machine specs?

Its with the 2,4 GHz i5, 8 gigs of RAM. I know, not optimal for this game!

I see that your machine only has the Intel Iris gpu? Is that correct?

If so, you might want to bring the graphics settings down as low and possible and try that way. That could cause your issues besides a bad installation (I have assumed that have tried verifying your game files. If not then try that) Also, WotC drastically improves performance and loading times. It could lead to better performance (or could not).

Another thing that you should note about XCOM 2 (especially vanilla) is that it is a vicious memory hog (especially when using mods) as time passes during a play session. It might help to free up your ram during extended play sessions. I use CleanMyMac purely for this function (otherwise it's not a very useful piece of sotware).

If you do not want to purchase CleanMyMac you can manually free up your ram from the terminal. It isn't as difficult or scary as it sounds. Open terminal and type:

sudo purge

You will be asked to input your computer password. Go ahead. The system will then free up inactive RAM that the game swallows up and should stabilize performance. Note that your computer will be unresponsive for a few moments while this is happening. It is perfectly fine to do this while simply alt+tabbing out of the game. Next close terminal and resume play.

These are the only actions that you can take tp resolve this issue, besides purchasing a machine that meets the recommended requirements better.

Thats correct, its the Intel Iris. I tried to reduce the resolution before - not going to absolute minimum though as it would look crap - that did not change much.

I had the integrity of the game data verified, no issues there.

Your point with the memory could be an issue. I have no probs using the terminal, do you sudo purge the memory during the gaming session or before firing up the game?

WotC does in fact improve the performance, with the exception of starting up the game. Loading the game into main menu takes literally five minutes. After that its fairly fast with all loads.

[SunDrippedDevil]

I do it before to free up as much RAM as possible and periodically each the session to free up memory.

Hope it resolves your issues.

I'm also having a similar issue: XCOM 2 was running perfectly and never crashed untill I was more than half way through my first campaign and suddenly at the start of one turn, it always crashes. I tried cleaning memory and the game was running 45 fps + but it still it crashes on the start of my turn. Any one know why this is happening?

I think I'll quit playing after 20 min. Super slow on my mac i7 16gb of ram, with all cleaned and fast. I throw money on the trash buying this game. Don't buy if got mac.

[SunDrippedDevil]

You need to flush your ram several times if you are playing just the base games to free it up.

Also tweaking the ini file to remove some visual effect like god rays etc.

Have all the graphic settings on low.

Without the expansion, this game doesn't perform well on intel-based apple machines.
