Quake 3 crashes when 'fight' pressed - Mac 13.4.1

I’ve followed all the instructions, Quake starts up, menu all fine, but when I go to start single player, it flashes up with ‘awaiting connection’ then crashes.

Same with multiplayer, but I get the error hunk_alloc failed on (7 digit number)

On team arena it gives an error about missionpack/pak0.pk3

On my original Quake install from the CD, there isn’t a pak0.pk3 in the missionpack folder!

Please help!


First thing to try would be updating macOS to 13.5
