After giving my iMac a great review, I am now having some serious screen issues. The screen has gotten progressively worse as far as a BIG yellow stain growing across the bottom half. And it IS getting bigger. And, FLICKERING. The screen blinking completely off at times.... I thought getting everything loaded was a huge pain...it has taken 5 days. That were filled with joy until tonight. so...NO, IT IS NOT SAFE TO PURCHASE AN APPLE IMAC YET!
