Hi i've taken my 09 iMac (2.8 i7) in for a Genius to have a look at it - he confirmed that the Logic Board needs replaced. They basically told me to take the iMac with me until they could fit me in for repair. I had to lug it through 2 sets of elevators, 2 car parks, 2 sets of escalators and 2 sets of stairs to get it to the store. And then when I get there - told to take it home to have to bring it in again.... So basically its going to take a minimum of 10 days - more likely 14 days to turn around the repair. The mac is still usable but is there some sort of SLA where they have to fix it with a certain amount of time?
