So I upgraded the RAM in my 2006 Mac Mini 1.83 a year or so ago. Thing worked fine until the other day. I purchased Applecare for this Mini in case anything went wrong. Something finally did-system will NOT boot, nor even power on, but the cooling fan runs at high speed continuously when the Mini is plugged in. Took it to a "genius" bar, and the guy was THE BIGGEST ASS ever. He FLIPPED THE HELL OUT when he found out I had opened the case. Took him 20 minutes to hunt it down, but he finally found some terms and conditions that state moding a Mini voids the warranty. I have had many people tell me, including Apple resellers, that adding RAM to a mini does NOT void the warranty. So anyway, I guess I am mostly pissed because the IDIOT DOLT at the "genius" bar knew less about computers than my 11 year old son and was determined to not give me the time of day because I had "sinned" and gone against Almighty Apple's wishes. The JERK had no interest in helping trouble shoot once he found out I opened the box. ALL HE DID was plug the stupind thing in, never even LOOKED inside it. Just put the top back on and plugged it in. I wish I could get the mini fixed, but they wanted nearly $400 for out of warranty service to which I politely declined. It had become a spare computer anyway. I own FIVE minis, TWO Macbooks, TWO iPhones, and at least FOUR iPods. I have spent in excess of $5,000 on Apple stuff in the last 18 months. I buy APPLECARE for EVERYTHING. I am so goddamn pissed at Apple I swear I never want another one of their products again. AND, I tried to find a place on the website to complain-good luck with that. I spent 15 minutes going off on the store manager and got NOTHING. APPLE-YOU SUCK-this is NO WAY to treat your customers. This is something I would expect from DELL or HP-NOT APPLE.
