Hi, I've finally gotten Snow Leopard on my Mac Book Pro, after jumping through hoops to get there - Disc not GUID, then when it was, SL not believing that the disc was bootable. Due to this, I nuked the hard drive, installed SL and then restored all settings and apps from my latest time machine back up, whilst physically cabled to my Airport Extreme Base Station. Whilst I left it do that, it finished the restore, and also did a couple of hourly back ups. All hunky dorey so far. Now that I'm using wireless, I notice that Time Machine kicks in as normal to do a back up. The icon starts whizzing round, and it starts calculating the changes to back up. But that's it. It progresses up to 99%, and then just sits there. I've left it like that for several hours, to see if it's actually going to complete, but nothing happens. Is there something I can look at to see if I can prod it into action? My backups go to a Drobo hanging off a Power Mac G4 on FW800, physically networked to the AEBS. Thanks in advance, GOO.
