Hi guys. I just bought a new 240gb SSD from OWC, swapped out the drive of my mid 2012 MacBook Pro, installed a fresh copy of Mavericks on it and was working fine for a little while. I then started the task of installing Pro Tools, then as I was installing the 2nd part (virtual instruments) the installer froze, then froze the whole computer, curser wouldn't move at all and the whole computer was not responding. I left it for a while as I know these things happen but after about 20 minutes still nothing, so I hard booted the computer and it started up sweet. I attempted to install again and same thing happened!!! But this time, after hard booting it is stuck on the grey apple screen with the loading wheel spinning. Any help would be much appreciated. My plan is to reinstall my old HDD (still fully functioning), download Mountain Lion and start again (a little less buggy and faster for Pro Tools??) Cheers for any help!
