I can get it to back up fine if I manually click Back up now, otherwise when the next scheduled backup time comes and passes, it does nothing except change the next scheduled backup time to some time later. The Time Machine drive is connected to the AirPort Extreme. There is a MacBook (Early 2006) configured to back up to the same drive which does it with no problem. WHY?
2. iMac (Late 2009), I switched on Internet Sharing from Ethernet to AirPort yesterday and it worked fine. Today, there was no arrow on the Airport menubar icon, it wasn't sharing, but otherwise it was normal. If I try to switch on Internet Sharing to AirPort, the arrow never shows up, Console log says the AirPort thing exited with code 1, and will be restarted by launchd in 10 seconds, so something seems to have crashed. This message is logged to Console indefinitely every 10 seconds, so it continues to crash as soon as it's respawned. I also cannot create an ad-hoc Computer-to-Computer network on this computer, same problem. AirPort debug log seems to show it fails to assign BSSID to a channel in order to become the AirPort server for others to connect to.
Search of the Internet shows a lot of people had this problem with Snow Leopard, some were fixed when updating to 10.6.2 or AirPort Client Update 2009-002. The computer came preinstalled with 10.6.2 and the AirPort update was downloaded and installed last week when setting up the computer out of the box. Tried all manner of possible fixes apart from downright reinstalling the whole OS since it was set up in a work environment, nothing works. WHAT THE FUCK IS THIS SHIT?
As far as I know, this is a nasty bug that Apple hasn't been able to fix since Snow Leopard came out. Fucking ridiculous.
I've had weird issues with internet connection sharing in that it would sometimes just shut off.
Such is networking. It's no fun.
