Well I've got this Macbook Air with 10.5.6 on it till Sunday. Work have loaned it to me for a few days to get a feel for it. I've used the OS before (10.2) so use to it's difficulties. I'm not particularly sure how it's been set up. It was someone who works for Apple who has set it up and every time I restart it wipes all my changes, even documents I saved. Also there is an admin password so when I try and even update it asks for it. Quick bit of Googling led me to Single User Mode but whenever I try to load it it just boots up properly.

What could have been done to prevent this? I youtubed it quick to make sure I was doing it right, turn on then press/hold Cmd+S. No such luck. Any ideas? Determined to do this, they can always reinstall the OS if needed.

Also there's no disc drive, is there anyway to use a Linux/Windows drive over a network? Or use a Linux/Windows machine to host the MAC OS installation files and do a network install?

The macbook air is designed around the very important principles that users don't need to install things from, quite frankly, antiquated CDs & DVDs. Instead, for obvious reasons, it is much more important that any new laptop should be able to fit in a Manilla envelope.

I never had any luck trying to share between Windows / Apple. But I have a very short attention span and couldn't be bothered.

Good Luck.

OS X just has SMB sharing the same as Windows if you want to transfer files across, got to Go > Connect to Serevr then type smb:// followed by the IP address or name of the PC to connect to. You can also use Remote Disc with an Air to get files across and even install the OS from a disc in another PC or Mac: http://support.apple.com/kb/HT1777
