Hi Darius,
The combination of OSX 10.8.3 and VMware 5.0.3 has not been a success for me.
VMware is hanging regularly, I got the Mac Beach Ball appear - I was (after 15 minutes) able to get back from Full Screen to Window mode, and found that VMware is "Not Responding" whereas the other app I had open (Mac Mail) was still working OK.
I was able to grab the Support information using the Help option and will open a ticket.
I have reveted back to 5.0.1, and so far it has worked troublefree - I'll see how this works out.
I'll open a new thread.
