RAM + Swap almost full (running out of physical and virtual memory)
I will start by saying that I know very little about technology. But I teach online using an old MacBook Air, and up until recently, it has worked great! But in the last few months, it has slowed down dramatically and particularly giving me problems during my Zoom meetings (lagging videos and my students saying that my shared screen is blurry at times). I now get a frequent pop-up saying "RAM + Swap almost full" ("running out of physical and virtual memory").
I have been using "CleanMyMac" to try to identify and fix any problems, but it seems to be showing that everything is fine. I have started digging around the internet trying to find solutions, and I saw some saying that it was important to run a check using EtreCheckPro. I have done that, but I still do not know what any of it means. Is there anyone that can help me? How can I share the report results? And which parts are needed?
I will be extremely grateful to anyone who can help!
MacBook Air 13″, macOS 11.7
