I successfully loaded all programs and files last night, whittling the available space on the hard drive to a mere 129 Gigabytes. But after a morning's work at home, I came in to the office, and have been completely stuck since - as the laptop isn't responding to any keyboard or trackpad input, and at the same time, the laptop's fans are whirring noisily below. A pair of restarts and a single shut down later, and I'm still feeling like world's biggest Apple fanboy moron.
After about 30-45 minutes of messing with this, I finally unhooked a USB keyboard and mouse from the old G4 desktop and attached it to the MacBook Pro, so the laptop is sitting in front of the USB keyboard, making things awkward and ridiculously duplicitous.
So far, Apple's support site hasn't been much help, nor has any amount of Google searching, System Preference manipulation, or random key hitting. For now, while I can use the USB keyboard, it's no kind of long-term solution, and I'd have to say I'm seriously annoyed.
UPDATE: According to Apple's support site, I'm not the only one with the issue... and so far, the only solution is to get it repaired. Not good!Any Mac fans out there who have a good suggestion for me so the MacBook Pro's first day isn't ruined?
