I've purchased a Samsung external SSD with the intention of using it as the boot disk. I've formatted it Mac OS Extended (Journaled), and I've been told that I can 'restore' it from the Time Machine back up. But all I get then is a clone of the TM back up drive. Can someone explain in simplest terms how I go about this? Preferably I'd just like to move everything over from the internal HD and then boot from the new SSD. How do I do this? Or is it as simple as drag and drop? I've tried Googling but there's so much conflicting information out there, so I thought I'd just come straight to the experts.

  • What did you actually do? You can't drag and drop or just make a duplicate of your TM backup disk. You need to restore the backup including the OS to your SSD as described here support.apple.com/en-us/HT203981#macos After you have done that press the altkey on startup and pick your external drive to boot from. – lx07 Jun 28 at 17:36
  • I use Carbon Copy Cloner to duplicate my internal drive to an external drive. see:bombich.com – historystamp Jun 28 at 19:40
