I am without wired internet for 3 weeks while I change providers. I rented a 4G portable WiFi router to tide me over. However, it is only allowed 5gb / day before throttling. I put my Windows PC on data saving mode but cannot find an equivalent on MacOS (Big Sur).
Is there a way to easily stop MacOS from downloading stuff in the background etc? Or do I need to go through everything and turn off automatic updates etc?
