Unreal Tournament crashing on mac

I get this crash and error at random intervals, bot matches seem to work fine, except for Team Deathmatch,
and multiplayer games on servers. I have the most success playing bot deathmatches and team capture the flag, the rest of the game modes randomly crash with this error.

Im running Mac Sierra OS
iMac (27-inch, Late 2013)
3.4 GHz Intel Core i5
24 GB 1600 MHz DDR3
NVIDIA GeForce GTX 775M 2048 MB

the error is >>
