I’m having constant 0.5 to 4 minute freezes running Unity (roughly every 5 - 15 minutes). They’re stopping everything – can’t even switch to a different application. I’ve dropped Mono and went to Sublime Text – but no improvement.
Any idea what I could look for? It often happens after the game is stopped – or when I switch Application. But not only then.
Thanks!
Did you try 4.3.1?
The exact same thing keeps happening to me… It’s driving me insane!
I have closed all other apps, disconnected internet, restarted Mac and have no external monitors connected and yet it still freezes every 5 min for between 15-30 seconds.
Yes. I keep having 1-5 minute freezes every 15-20 minutes. It gets worse over time. Sometimes I just quit and restart Unity hoping to increase the periods when it works fine. It feels like Unity is struggling with other apps, but I don’t know of course.
Oh and 4.3.1 didn’t help. Maybe it got a little tiny bit better. 
Same issue discussed here: http://forum.unity3d.com/threads/206611-Performance-issues-using-Mac-OS-10-9-(Mavericks)-and-Unity-4-2-2
No solution in sight although Unity do acknowledge the issue.
