i got very recently this macbook, and it was working fine until when i turned off and on again for few times over the course of like 2 days, it started acting really wrong, in short, the macbook is really snappy, switches between virtual desktops easily, i managed to have few tabs with a video playing, whatsapp, telegram and editing photos on Luminar (the program i use) with not a really big deal, now the macbook basically struggles to run, the wallpaper isn't there anymore and even changing it doesn't matter, animation are basically nonexistent, for the application panel (running sequoia with Opencore legagy) pops after few seconds, and all is incredibly slowed down, basically unusable, but with Stats open the usage of all the stuff is barely touching 60%, CPU after the initial startup gets very low, gpu not being used, 55% of ram ish, which is normal for the other days aswell and SSD at 35%, for contex. the SSD is the original one, i'm planning to change it, i haven't changed the battery either and it suggest to be changed, it still has 2 hours max of battery life tho, i did change the thermal paste since it was very very dry.

i don't know what to do, is changing that stuff going to fix anything?
