I was a loyal Windows user forever. However, I hate Windows 8. So I made the jump to the iMac. I purchased it on Feb 9 and it arrived yesterday. I plan on setting it up tomorrow. After reading about issues on here with the new iMacs how can I test out mine to see if it has any of the issues? I have seen the yellow screen, monitor issues, and also issues with the Fusion drive posted on here. The following are the specs on my iMac. I will be upgrading the memory in a couple of weeks myself. 3.4GHz Intel Core i7 Quad-Core 8GB of 1600Hz DDR3 RAM 3TB Fusion Drive nVIDIA GeForce GTX 680MX Graphics (2GB) I am sure I will have lots of questions. Thanks in advance.
