Websites freezing after a group project
Hello! I have a macbook air with intel, released on March 2020. I have been using it for school since I bought it. Recently (a day ago) I had a group project for several days in school which required me to use online microsoft apps (shared word and powerpoint). After the group project I noticed when I went to some websites on safari, they would freeze. And this has never happened before. Youtube videos doesn't work anymore because the site is loading, and the same with Instagram and some other websites.
Obviously I can't update to the lastest macos, but it is up to date as a 2020 macbook air can get. My system storage is only half full, and I've also tried: 1) pausing the icloud relay 2) deleting all website datas 3)restarting the computer and 4) force quitting safari.
There is only a word doc and 3 tabs on safari open.
Do I have to buy a new macbook?
Thanks.
