In thirty years of repairing Apples and Macs, I've had one person ask if I was certified. To begin with Apple wouldn't offer certification to anyone that didn't work for them or their Authorized Repair Providers. I've looked at the programs Apple has offered over the last few years, gotten some of the training books, and in my opinion it's only a way to extort money from me. To my knowledge, I can't just take the exams, I have to pay for the whole shebang. True, I became an Authorized Apple Var, but that didn't have that much to do with Apple, rather the distributors. The requirements for becoming an Authorized Service Provider, last I checked was $250,000 in inventory parts. I tried for years to get that authorization but they were limited to so many per capita. Currently my area has one authorized service provider, Best Buy. The tech has had three days of Apple training, the last time I checked. He sends everything off, and charges about $1000.00 for any repair. My customers report that they were quoted $1000 for a DC IN board on a Aluminum G4. I've had numerous reports of this type of extortion. Maybe someday Apple will treat the people who love her with respect, but I've been *^%!* slapped enough. "Certifications? We don't need no stinkin certifications."
