Macbook Air not recognizing usb drive



  • Phil Reilly

    Plug in while running os x. You should get a banner to format(don't). Restart & hold down the option key. You should see the usb along with the other drives. If it doesn't show check to see if it works on another computer.

    I tried a new usb stick (8gb) and it worked. Thx for the help.
