how do I delete doubles of photos, clean up hard drive?
aMy new Pro with 750 gig hard drive is very slow lately. Since I am a new Mac user, how do I get rid of doubles of photos that Iphoto seemed to do on its own?
I have only 13 gig of storage, but is there a defrag program or some other way to find out why computer is slow?
thanks
MacBook Pro, Mac OS X (10.7.4)
