So I decided to 'upgrade' my copy of QuickTime 7 on my old Tiger machine to QuickTime Pro. I've bought every version's Pro key since they first started selling them with QuickTime Pro 3 in 1998. Of course, I purchased the QT7 Pro key back when QT7 first came out in 2005, and the way to look up the old numbers was to go to the Apple Store, log in, go to your account, and go to "Software Downloads". Well, that section disappeared at some recent website update, and the "Your Orders" section only goes back 18 months. So I contacted Apple Support. The first person I talked to had no idea what I was talking about. "What is the serial or IMEI of the device?" Uh, no, it's not a device, it's Mac software. "Okay, what is the serial number of the Mac?" Well, that's irrelevant, it's Apple branded software that is independent of an individual Mac, and, in fact, can be used on Windows. "Okay, what is the serial number of the software?" That's why I'm calling!!! The person she escalated me to got it right away, though. He knew what I was talking about (a QuickTime Pro key,) and tried to help. In the end, though, it was long enough ago that he couldn't look it up. He even called the Apple Store help (he was "Mac help",) to see if they could get it, but they couldn't either. So he did some more digging, and found that there is a separate QuickTime support line. Completely independent of the rest of Apple's support system, different phone number, he can't transfer to it. He warned me "Don't mention the iPod or iPhone, they won't know those exist. Oh, and you may have to use a rotary phone to call them." Old timer support guy humor for the win!
