When I start the editor in Mac, ever since the HOTS patch it hasn't worked. It just keeps spinning, in the activity monitor it says not responding and just getting spinning beach ball.

Similar to other users problems as stated here: http://us.battle.net/sc2/en/forum/topic/8568987383

From the crash log:

-----------------------------------------------
<Inspector.Platform> Mac
<Inspector.Module> Editor
<Inspector.Priority> 1 - Critical
<Inspector.Assignments> .Mac Team
<Inspector.Summary> EXC_BAD_ACCESS (KERN_PROTECTION_FAILURE at 0x00000000)
<ErrorType> EXC_BAD_ACCESS

I've tried reinstalling the whole thing, still happens.
