I have a MBP 13 inch with OSX Lion on it (late 2011 model).
Since a few months now it's been slower than when out of the box even though I didin't really start using it differently since then, except fill up the hard drive but the slowing down problem has occured with 150 gb left or 50 like now.
Anyway I was considering doing the "Repair the Hard Drive and Permissions" thing of the Recovery HD (if I got it correctly) to try to see if that would help.
1) Could this help ?
2) Also is it risky to the point where I should back up my hard drive before doing it ? Because I'm on holidays and I have no means to do a time machine or anything like that beforehand.
3) Do I need an internet connection to do this ?
Thank you for your help !
