I thought I would start a thread for those suffering from the yellow tint issue, which might prove helpful for others beset by the same affliction. My configuration is as follows: MacBook Pro 15.4/2.53/CTO/HR Glossy/500GB @ 7200rpm Ordered: Apr. 14 Delivered: Apr. 21 Step 1. Genius Bar Lenox Apple Store Genius was a friendly guy. He had a hard time seeing the problem at first, but when I kept pointing it out he finally saw it. He wrote up a repair order and asked me to call 800-MY-APPLE to arrange for the return of the unit, because it was a CTO, which he could not handle in-store. In-store time: 15 minutes. Step 2. AppleCare I called the 800 toll-free number and after being connected to the right department, because "robo-voice" could not figure out what I wanted, I told the first representative of my problem. He told me that he had exactly the same problem with his 13-inch MacBook Pro and was sympathetic, but had to hand me off to his supervisor. His supervisor had me try zapping the PRAM and resetting the System Management Controller (SMC), which, of course, did not help. After taking all my information all over *again* (you'd think our data was centralized, but it's not), I was told that I would be contacted by yet another Apple customer care person by phone within 24 hours, who would instruct me on how to return the unit with mailing labels provided via e-mail. So now I wait. Time wasted so far: one hour for first missed Genius Bar appointment plus another hour today for appointment and phone call. Stay tuned.
