I picked up Tiger last night, but the DVD in the box was corrrupt. I tried cleaning it with a lens grade cleaning cloth (radial strokes only), and then tried it in both my Macs. In each case, it failed the “verifying your DVD” check at the 68% mark. I’m going to go down to the Mac shop again today to see if they still have any copies left that I can swap for.
On a related note: I’m going to back up this site (and the MySQL database that WordPress runs on) before I upgrade. I haven’t heard of any problems getting it all running on Tiger, but if you can’t find us for a while over the next few days, at least you’ll know why.
