I have upgraded to from a 2011 13" MacBook Pro to a 2012 13" MacBook Pro... found serious software slow down and wheel of death after installing Mountain Lion on 2011 MacBook Pro... Upgraded to 2012 MacBook Pro and used Migration assistant... dont have the huge slow down, but dont know if new machine is performing slower than its could.
Question: Is there any way that Migration assistance could copy problem software to new MacBook Pro or does it automatically honour newer software?
