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.
