I just got my 2011 MBP replaced by Apple with a 2012 MBP and I'm in a rather odd situation. I run my MBP in a SSD+HDD setup with OSX in the SSD in the main bay and W8 bootcamp in the HDD in the superdrive compartment. However, I noticed that in such a configuration OSX runs fine, however my bootcamp partition will not load at all. And when I put the SSD in the superdrive compartment and the HDD in the main bay, bootcamp works perfectly. However I get more beachballs in OSX than a sunny day at the beach. This is driving me crazy . Anyone got a fix for this??? Or have any of you even encountered this???
