Hey, Can anyone give me some advice? I am about to upgrade an iMac from version 9.2.2 to OSX. I need to be sure that i will not reformat or erase the drives as I am not able to back up any info at this time. Is it as simple as pressing the 'install MacOSX' icon? thanks in advance, Eboy p.s. I'm new here, so apologies if this has been answered a thousand times. I searched for the answer but could not find what I was looking for.
