Hello everyone, I copied a lot of information to my friend's mid-2010 MBP, about 80GB of data. Used iChat - transfer took about three hours but it got there. Before the transfer her laptop was very quick - didn't have much installed, plenty of free space. After the transfer, the laptop still have a lot of free space (>100GB) but is very slow. Before the laptop would take maybe 1 minute to boot up.. now it's over three. She experiences bouncing beach balls when loading applications as well. Suggestions? Maybe I need to defrag the laptop? Thanks all, Daniel.
