My KSP constantly freezes

[TheBro21]

My KSP keeps freezing constantly. Always after about 20 minutes of gameplay. It always freezes on the loading screen on vessel recovery, or reverting to launch, or assembly. The only mods I am using are the latest versions of MechJeb2, KW Rocketry, and Kerbal Engineer Redux. I have KSP on Steam, and saw a lot of posts saying that a x64 version would help. However, I am a mac user, and I do not see anything like KSP_x64.exe or KSP_x64.app Also I saw something related to freezing, where you enter -force-gfx-xt into the shortcut options in properties (don't know the name, because I am not a Windows user). It is not a problem related to minimum requirements, because even at lowest graphics, it freezes. It also keeps freezing when I remove mods. I tried Verifying Integrity of Steam Cache, but that only delayed the freeze. At the moment it froze when I went to the Space Center, the KSP.log said this:

Yup, you're out of memory - not actual physical RAM mind you, just that which a 32bit app can address. There's no 64bit Mac client as yet.

Try dropping the texture quality, and/or ActiveTextureManagement - I'm not sure what format KWs textures are, but it may help.

There appear to be serious memory-management issues with Unity on MacOS at the moment, but I'm not sure there's anything we can do about them. Someone more Mac-expert-ish may have further ideas though.

Seems like you're running out of memory:

Memory leaks are a frequent cause of crash in KSP. Aside from the few solutions you already saw, I don't know others for Mac as it is not frequently used compared to Windows.

Still, there are probably other users who will provide real solutions, so just wait a bit, and good luck !

OFC, the other option is a GNU/Linux dual-boot.

There's 64bit over there already, though with luck it comes to other platforms soon.

[TheBro21]

Ok, then the plausible solution is to get a Windows or Linux partition.

Ok, then the plausible solution is to get a Windows or Linux partition.

There, fixed

Actually, Linux has the only stable/supported 64bit player at the moment, though the demand is strong for this on Windows so we may well see it with 1.1.
