I have aquired a macbook air laptop. I am an advanced PC techie but pretty novice on the mac. It seemed to be running fine, I loaded acrobat reader on it and the machine is now sluggish as heck. I pulled acrobat back off, checked disk space - 5 gigs free - so the hard disk should have enough space on it. What else can I check in terms of tuning up?
Much appreciated, would like to do this sooner rather than later so max points. If you have further questions, please ask. I believe it to be running osx.
