Hi Folks - I've got a 13" Mac Air, mid-2013, 1.3 GHz Intel Core i5. I'm using High Sierra, 10.13.3. I don't really know what any of that means, being both older and ignorant of tech stuff. I also don't know much about these two images I've posted, but I think they are of import in maybe figuring out my problem. And that problem is this: A few months ago, the beachball starting showing up, and lately the problem has gotten much worse. The computer just basically freezes for a bit whilst typing an email in yahoo or working on Final Draft screenplay software, the two main things I use this for. Usually the beachball makes an apperance at these times as well. Sometimes I'll type a few words and nothing happens at first, and like 30 seconds later the words spit out on the screen in an extremely delayed reaction. Is there any chance a fool like me who hears RAM and thinks of an animal can address this problem on my own, or am I sentenced to a trip the Mac Store?
