Wirelessly posted My work Toughbook, which really isn't that tough, has a broken screen after a frustrating half hour failing to send an email with a 382kb attachment (which task my iPhone managed in less than 2 seconds). I'll get a replacement pretty soon, but there are some files I need on the hard drive. The drive is encrypted, so putting it in an external enclosure is no good. The screen is broken, and I don't have a monitor. I only have a user account, so I can't install any software. Is there a way to use my Air as a display?
