So the iMac died again, this time really. Even the installation DVD can’t see the hard drive now, so I can’t reinstall the system. Appointment at the Apple store is for tonight. Let’s hope I’m coming home with a working machine. Then I’ll have to spend yet another day reinstalling stuff. Those with Macs, especially Intel-based, apparently should avoid the update to system 10.4.10 like the plague—and this is from Apple support (but it’s probably too late for most people).
