Should I factory reset my macbook?
I had exited out of some memory applications in the activity section with the CPU, Memory, and Energy, and I have since learned that may have been bad because many are required by MacOS. I don't know which ones I had stopped and deleted, but my Macbook pro 2019 constantly tells me "this website is using significant memory mac". My cache is all deleted and cookies and its just one tab, a movie. I wanted to know if A) The memory applications that I deleted come back when I shut down my computer, and B) If its worth factory resetting. Any help would be greatly appreciated!
MacBook Pro 13", macOS 10.15
