Ok guys I have a question for a friend who is having problems with updating to 10.5.6 from 10.5.5. She has an iMac and goes thru the update process and everytime gets the error message after its downloaded cant mount the image I think. I haven't seen it but thats what she is telling me. Anyone know what the problem is?????? She has tried several times and it's always the same thing. What could it be???
