You're running ZBrush inside a virtual machine via Parallels, so that view of the task manager might not be your actual cpu usage reading, but the virtual machines. Try it again, and instead view the cpu usage via the activity monitor in OS X.
I tried the Windows version on my MBP using Crossover and it works as it should, hardly using any CPU for the same basic tasks. The Mac version of ZBrush does not work correctly since the processor usage is not normal compared the the Windows version.
Please show me any other app on OS X that uses as much CPU as what ZBrush is. In the screen capture that I took, it's using 750% cpu, and that's simply rotating the view with a basic mesh. It's hammering the CPU harder than any render engine and it's definitely not normal. It causes the fans to start immediately and will certainly cause damage. Other apps that uses high CPU like rendering are controlled, then will not try to use more CPU than what's there, but this bug seems to try and use more CPU than anything available and is hammering the processor. Definitely not useable like this.

Using ZBrush on Mac in this state is a good way to fry your laptop. Funny thing is that using the Windows version on Mac via Parallels works fine. Pixologic obviously doesn't pay as much attention to the Mac port...
Doing the same thing in Windows via Fusion... not a problem. However the problem is that I'm supposed to be able to use ZBrush in OS X and not have to use the Windows version...
