I am a user of rMBP13 early13 and have one question that I can't solve on my own. I have no problems using ML - absolutely love it. I mainly use safari, word, photoshop, lightroom - thats all. Some random stuff like youtube, movies. Just thinking should I upgrade to Mavericks? Should I do a clean install (no clue how to do it) oraz should I consider just click "upgrade" and see how it goes? Didn't do the upgrade in the begining because there were problems with Word. I think that now they are solved Should I upgrade or stick with ML and do it with the "upgrade" button?
