excessive memory ram usage on MacBook Air 2020

hello, i have gone to the apple store, spoken to apple support, and nothing they have done/told me to do has fixed this problem. my macbook air 2020 has 8gb of ram, but when looking at activity monitor, the memory used is always at 5gb or more. usually more like 6. if i look at my mom's computer, which is the same exact model bought at the same time, all of the applications she has running use about a tenth of what mine do. i also used to use google chrome, but switched to safari because the apple store employee said it might be better, but news flash, it's not. i'm seriously tired of trying to resolve this issue. below is my current activity monitor. my computer is updated, i usually never have more than like 10 tabs open at a time when using safari/chrome, i always clear my trash, my files are organized. i can't keep on doing this. if anyone has anything else i can look at, i will try. otherwise i will just have to wipe my computer and hope it works.

I'm sorry, but I don't understand what issue you are trying to resolve? The memory pressure on your system is green and well below 50% on the pressure history graph. Is the computer performing poorly, or is there some reason you feel this is an issue - besides looking at Activity Monitor (which is only slightly less bad than looking at the running Console logs for most people...)?


I don't see a single thing to even spend time diagnosing here; this computer appears to be running well.

Note that the 1.59 GB of Cached Files representi memory that nacOS can free at the drop of a hat. The idea of putting it to use for caching instead of leaving it completely free and idle is that if the machine needs the caches data before it needs to allocate more RAM, the cache can save a slow trip to a SSD or a mechanical hard drive to get the data.


The Swap Usef indicates that at one point, the system ran out of real RAM and simulated more using space on the startup drive. Some Seap Used is OK,, but just as you want to see Greens in the Memory Pressure graph, you want to see zero or low values for Swap Used.
