I know I am supposed to put things in here but I don't know how. I have a MacBook Pro Late 2013 with a 2.3 Intel Core i7. When some games start this it what it looks like. I have tried f5 but no luck.
Do you have any mods, or have you ever used or tried to use them? See the OSX thread in my signature for instructions on getting a system report to post here. Should probably look at the thread a few posts down about finding a log file as well. Not sure if the log will show anything; I really want to see the UI debugger output, but getting that set up is a little more involved.
