I am running OS X Sierra. The game is incapable of functioning in full screen (I tried 4.2 AND 4.3 before and after my OS upgrade from 10.11.5). It works kind of mediocre at best if full screen is NEVER switched on, but once full screen is turned on, the game just suddenly quits in a way that keeps the operating system from launching the unexpected quit notification and then upon clicking on it in an attempt to relaunch the game, just opens long enough to see the screen fade to black and the cursor disappear for only a moment then re-appear and the screen flashes back to the home screen. NEVER displaying the notification. What's even more strange is that I redownloaded the game and reinstalled it, yet this issue persists.

PS - I have yet to figure out how to turn off full screen mode via command prompt.

My first idea would be that the resolution set does not fit your screen.

You can edit settings outside of the game in your q3config.cfg. no idea where those would be on mac. either they are in /PATH/TO/GAME/q3ut4, or in your home folder under q3ut4/

For fullscreen want to change

seta r_fullscreen "1"

to "0"

Additionally, you could change

seta r_mode "THERE_WOULD_BE_A_NUMBER_HERE"

to something like "1" (that would be 640x480p)

also, there is this and other threads in the mac support forum.
