First my issues... So Apple have finally decided to come and pick my iMac up for repair. On two previous occasions, I had took into the local Apple store, in Sheffield (UK). The first time they replaced the iMac on the spot due to being in the 14 day return period, on the second time, they didn't see the issue that I had with the screen flicker, tearing of graphics and yellow tint, so wouldn't change it for me. So I rang Applecare the same day, and spoke to a very nice person, and they said as this was the 3rd time with the issue, I would be escalated above the normal level. They are coming to pick up the computer on Thursday, will they just replace the screen, or give me a new computer. I have a lot of data, and the computer isn't the stock I5 it has 12GB ram and other stuff, will they give me my computer back or give me a newer model with a better screen.
