My Late 2011 Entry Level 13" MacBook Pro is just getting really icky and slow. Many apps are glitching, programs like Safari and iTunes are having a hard time (iTunes is requiring a force quit to close, Safari can't handle flash content very well) and it's becoming annoying. I'm pretty much thinking that at this point I should do a complete reinstall of my OS. I have my music library backed up as well as my copies of CS5.5 & Office 2011, which are my two critical apps, so I am prepared. My question is, I've never really reinstalled a Mac OS before. Is it as easy as Windows? Am I also taking the proper approach, or should I try something else before I do a full reinstall?
