Hey guys, just today I received the new 250GB SSD that I want to swap for the 500GB HDD in my late 2011 MBP. I wasn't even considering this until I upgraded to Mavericks and experienced severe slowdown on the whole computer. (the only thing that got quicker for me was Safari) Since I was running Lion before, I didn't want to downgrade back and lose all the Mountain Lion features. I heard from some users that a possible reason for slowing down instead of having a speed increase on Mavericks was installing it on top of an existing OS instead of a clean install. I don't know if that has been debunked, but I figured it wouldn't be a bad time to upgrade to an SSD either. So I have a few questions- what are the first steps to getting a clean install of Mavericks on my new SSD? (Should I clone my old drive onto the SSD first?) With a clean install, should I backup my data on an external and then manually transfer over, or can I use my existing Time Machine backup? Thanks!
