I went ahead and downloaded the High Sierra installation file to my 2015 MacBook Pro 15, but after reading all the negative reviews, I've decided not to install it. So I'm guessing it's sitting somewhere on my hard drive, taking up space, but where? I'd really love to get this thing off my hard drive as if I had never downloaded it to begin with. Probably a really simple thing, and I'm sure I'm going to be embarrassed when someone points out where it is and how to do it. So that's my question, anyone have any idea how to find the file and delete it?
