I recently purchased Adobe Master Suite and installed it to my MBP. I found that this was a mistake cause it cluttered my brand new MBP. So I uninstalled it and realized how cluttered my MBP is already. I was wondering is there away that I can clear everything and re-install the OS without slowing down the Mac in any way? Just like if it was new? I know thats how PC's are and this is my first Mac so I don't know if that happens or not.
