mr_camouflage,
I am sorry, you are right that the steps I provided don't work on Mac.
Could you please try to use JMAP (http://docs.oracle.com/javase/6/docs/te ... /jmap.html) to generate dump once Studio hangs/hits 100% CPU usage? JMAP is included in JDK. If you have <JDK>/bin added to your path it should be enough to execute
jmap -dump:live,file=heap.dump.hprof,format=b <Zend_Studio_pid>
Thank you
