Looking at my router’s activity monitor I noticed that both my 2017 5K iMac and 2020 MacBook Air (M1) had significant amounts of unexplained network activity. I was notified by my ISP that I was close to using my monthly allocated download limits in just the first few days of the month. Paul noticed that on macOS Big Sur, an Apple News app process called newsd was downloading huge amounts of data in the background. The Apple News download bug was raised on the Apple support forums at the end of December by user paulfromminnetonka (h/t Nate). While Apple hasn’t issued a patch to the app itself, there is another way to fix the Apple News download bug that’s causing background downloads of up to 60GB+ a day. The Apple News app seems to have a flaw in macOS Big Sur that’s causing very large background downloads for some users.
