When I try to start a VM my iMac completely freezes. I have to shut it down by holding the power button. Some additional backgrounds:
I reinstalled Mac OS X yesterday because I built a SSD into my iMac. I reinstalled Mac OS X Snow Leopard. I updated everything and reinstalled the software I already used before.
Then I copied back my VM's Hard Disk file I had before (Windows XP Professional). I created a new VM with this Hard Disk file. I configure it the same as before. But when I try to start it my iMac freezes completely.
I tried to assign less RAM: didn't help.
I reinstalled VirtualBox and created a fresh VM: Windows XP copied all the files but when it tried to start my iMac froze again.
I have 8GB of RAM and it didn't cause any problems before today. And I use Aperture which took almost 2GB while creating thumbnails and nothing crashed.
Any help would be really useful
Thank you.
