This is a repost from the iMac forum...I think that is mostly hardware talk and I need some software help. Thanks, guys. Hi all- I've done a clean install of windows a bunch of times in the past, but this will be my first go around in OSX. Let me break down my situation- I have a 2011 21.5" iMac. I just bought an SSD. I want to install the SSD to run the OS and apps to speed things up. I figure this is a good time to do a clean mountain lion install as this computer came with Snow Leopard and i've done the upgrade installs for both lion and ML. I also have a Windows 7 Bootcamp install on my current HD. I have a 2TB external HD for time machine. I have all of my music and pictures on my HD right now, backed up to the time machine drive. The OS and all of my Apps (photoshop/lightroom/steam/games/etc) are all on the HD. I have found all of the install kits and videos from OWC and iFixit for how to do the hardware part of the install, but I haven't been able to get a step by step guide for what to do once i put it all back together. As I understand it, when i boot it up, the SSD will essentially be a new hard drive (empty). Can someone point me to, or even write up for me, a step by step process of what I need to do to get the system running as well as possible? Thank you!!!!
