I recently got my first mac computer ( Retina Macbook Pro 2.6/16/256) and after playing around on the computer for a couple of days I have a few questions. 1. How do you delete apps from a mac? Tried and tried but can't figure this one out. 2. What issues should I look for on the computer before deciding to keep it? (EX: Image retention, dead pixels, ect.) 3. (I posted this one on a thread a few days ago but hasn't been answered) Do the iCarbons retina macbook skins leave the computer sticky after you take them off the computer when they have already been there for a long period of time? Need to know this one as I plan on selling it down the road and the skin could hurt the resale value IMO.
