Hi everyone I got my iMac yesterday and I thought I was not a victim of the yellow of the yellow screen issues. I wasn't but I do have a rather annoying issue. There is a piece of dust under the screen it's not very large but is extremely bothersome. I was really looking forward to the 27 inch iMac. I love it, but now I'm upset. It was also a special custom build with a 512gb flash storage option. I am thinking of returning it, but should I?
