Current iMac boots up using an external HD. Connected via FW800. Just bought new macbook air and a new external HD with thunderbolt. I want to use the same HD content to boot up my new macbook air. Can I simply copy (click and drag) the old HD to my new Thunderbolt HD and use it for boot up, or do I need to do something specific to enable my macbook air to bootup using the new HD (with the old content)?
MacBook Air, iOS 8.1.1, iMac to McBook Air
You need to use a program such as the Disk Utility, Carbon Copy Cloner, or SuperDuper to clone the OS, and you need to ensure that the OS is at least as new as the version which shipped with the MacBook Air.

Thanks Niel. I assume I would connect both the Old HD and my new HD to the iMac and then start up normally (no Option button) and then open disk utility. Both HD symbols appear on the desktop. How would I then clone the old HD?
Use the Disk Utility’s Restore function.
