Hey all, I have a mid 2012 Macbook Pro that I use daily for school with being a computer science major. Lately my macbook has been slow as all get out and has been annoying the living crap out of me. takes 5-10 minutes to load up safari or the app store and whatnot sometimes while others it takes like 5 seconds to load. So I am looking at just completely resetting my laptop back to factory settings and starting fresh again but have a few questions. 1. I have apps on my laptop I use all the time such as photoshop that I don't have the key for or anything that I really need and can't afford to lose. So, if I just drag and drop the photoshop app onto an external hard drive will this be able to just be transferred right back over, or will I need to completely re-download it? 2. Is there a way to somehow keep the list of my safari preferences, and my saved usernames and passwords on safari, or will I completely lose these when I restart the laptop after the reset? 3. Would it be best to keep all of my movies and tv shows that are on my laptop saved to an external hard drive and only transfer them over if I plan on putting them on my ipad/iphone and whatnot? Not sure if this will help with memory/speed.
