Late 2008 MBP running SL migrated to new 2011 MBP. Just did a straight firewire transfer of data. It's been VERY VERY unresponsive under the new MBP. Created a test user and all is well and fast under the new MBP. Grrr.. Tried logging into migrate user and disabled startup items. Still Buggy and at times, it becomes unresponsive. Just short of deleting the libraries from my user folder( which is fairly drastic)....and or just creating a new user and starting from scratch, any ideas or suggestions ya'll can provide to isolate it down.
