Hi, I have an iMac that has boot camp and parallels setup by my previous co-work worker who has since left the company and now I need to get this iMac booting back into Mac OSX and I have found no documentation, CD's or anything else that could help? I have tried pressing the Alt/Option key to get back to the MAC OS but no luck? There are no parallel tools installed on this iMac either so I have looked everywhere for an answer as to how I can get my Mac back...?? No luck at all even when I put a Snow leopard disc and boot with that in the slot? I think the iMac was running 10.5 before as this machine is about 2/3 yrs old. Can anyone help with this, it must surely just be a keyboard combination that I havent come across as yet? Cheers Phil
