I have a new MBP. I used Migration Assistant to load my old computer (applications, music, photos etc onto it, and then I upgraded the Mac OS to 10.12.6 Since then, my cursor often disappears and takes 3-10 seconds to reappear. This happens most when using Chrome when a lot of tabs are open. That said, I never have more than 15 open, and this never happened before. I assume there is some app or something else making the computer act buggy but I can't figure it out. Any thoughts about how to figure this out?
