Here's a frustrating one. I inherited a PC recently that had a USB 2.0 PCI card which I figured I'd try to get to work in my Mac. The card is based on the VIA VT6212 chipset and after some searching I found official drivers for the card (that only work with G4 Macs). Well, after rebooting the Mac the card seemed to work fine - it showed up in the system profiler and I could work with devices connected to it without any problems.

The company Commodore, once known for calculators, then this really awesome home computer (C=64), then this even more awesome computer (Amiga), then for management incomptence which ultimately led to its demise in the early 90's, is finally back to market with... a stupid PC with a fancy paint job. Yep, that's right, after being known for innovation they're selling a Windows-based PC aimed at the games market. What a total waste of twenty years of good PR. Idiots. I don't expect them to last very long.

I just installed the OSX 10.4.9 update on our PowerMac G4/533 at home and had a little bit of weirdness. The first time the machine was rebooted after the install it took several minutes for it to actually start booting, leaving the screen white until it was ready - needless to say this was rather concerning, but I left it alone for a while and it finally kicked in a-ok. The Mac Pro at work had no problems, however.
