Using Migration Assistant, I recently transferred hard drive contents from an older MacBook (67.5 GB on a 80 GB drive) to a slightly better MacBook with a 120 GB drive. To my surprise, the new MacBook now has 83.2 GB on it. I suspect that files have been duplicated and are now hidden. Is there a safe way of deleting hidden files that are bloating my hard drive?
I suggest first making sure that the files have, in fact, been duplicated. You can view hidden files by typing the following commands into terminal:
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
Could it be that the newer MB has a newer OS or more applications and that is what takes up more space?
to hide the hidden files again, open terminal and type:
defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder
