Slow and not support for multicore

Post by ed_co »

I can't get multicore working. I get a message saying turn the machine off.
And in overall is pretty slow, till the hardware graphic acceleration appears.
But the process is easy as hell. That's really good.

Thanks.

Some can have a VM with MacOSX as guest with more than one core?

I got a kernel panic on boot up after enabling a second core the first time.

Then I enabled 3d acceleration and enabled a second core and OS X boots up fine now. :D

Fair enough. Is incredible that some people here, can do that... if it's true, of course.
