Hello, I have an early 2011 MBP (2.3ghz i5/8gb ram) and i just ordered a Samsung 850 500gb evo. I know the easiest route in installing this would probably be to clone my hard drive. But imagine if i wanted to do something like crazy like start with a fresh install. Is it possible to install Mavericks on a blank ssd? I imagine it is best for me to stay on Mavericks since if i upgrade to Yosemite, it won't let me enable TRIM right? Thanks.
