This is a REAL photo I just took with my Sony Mavica whilst installing OS X 10.1 Developer Tools just now.
What happened was since the on-board clock on my laptop has NEVER worked, the clock was reset back to 1969 as usual when the rechargeable battery ran out again. I happened to notice this and reset the clock while Developer Tools was still installing (isn't multi-tasking wonderful?) and apparently progress, well, suffered.
There is so much irony here I swear I couldn't have made it up if I tried.
P.S. This all happened 30 minutes ago and the progress bar and time-remaining have not changed since.
p.s. the install finished about fifteen minutes after that
