I've got a Macbook Air 1,1 (original), tried from internal disk, usb flash, and usb hdd.... The longest i've gone is to boot it up using MacPostFactor 1.0.1, from external usb, but the os x installer showed up an error saying the installation is not complete and a log file, with the only options of rebooting, shutdown and send log files to Apple.. If you have a solution or know something I can do.... I won't give up.. Thanks in Advance!
