Dumb
If I'm absent, it's not just the vagaries of conenctions on the road, or neglect induced by the proximity of art and archaeology.
Prosperity, the Tinderbook, had been acting badly for two weeks before the trip. Before leaving, I decided I'd better get a new hard disk, and opted to have a pro come and install the thing.
Unfortunately, this particular professional thought that drag-copying a disk in Finder was a good way to proceed with replacing the system disk. That turns out not to be the case. I was at the office at 1am fixing the disk, with a taxi to the airport slated for 6.
And I'm still finding problems with permissions, everywhere. I'd have spent less time doing the whole thing myself, and saved a few hundred bucks.
