newsd process on Big Sur downloading MASSIVE amounts of traffic

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. 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.


So I installed Little Snitch on both machines to monitor traffic and in just a couple days the newsd process on the iMac downloaded 375GB and the Mini downloaded 130GB.


And specifically the downloaded traffic occurred with hostnames apple.news and c.apple.news. Both have valid signed certificates by Apple according to Little Snitch.


Although I use the News app on my iPad I don't regularly use it on either Mac.


Has anybody else experienced this activity? I'm wondering if there is a bug in Big Sur or I possibly have some sort of malware masquerading as legitimate? A scan with Malwarebytes is clean on both machines.


Thanks in advance for for any suggestions.



iMac 27″ 5K, macOS 11.2

I had the same problem on two Macs, a 2019 iMac and a late 2013 MacBook Pro. Both machines were downloading up to 90GB of data a day. I hit my data cap in 8 days. I talked to Apple Support and we looked at a number of things, and we kept coming back to the newsd process. So, on the iMac, I did a reinstall of Big Sur 11.1 and on the MacBook I turned off iCloud syncing for the News app in the System Preferences (iCloud Settings).


Turning off iCloud syncing for the News app is the thing that worked and stopped the bandwidth hogging.

Same problem here. Always used about 400-450 Gb / month with Xfinity. I haven't changed my daily data usage. Now I got a notice on the 20th last month that I was at 90% of my data cap. Crazy! I turned off iCloud syncing with News and force-quit the News app. Yet here I sit with Activity Monitor open and I'm watching the "data received" for newsd process slowly climbing. It was 6.89 Gb 10 minutes ago and now it's at 7.07 Gb. Then I simply opened without using the News app and watched it jump to 7.16 Gb. I've force-quit News app and Gb received is still increasing. What is going on and how do I stop it? And the irony is, I love the News app and pay for it.

Already disabled news syncing on my 2020 iMac but makes zero difference. Suddenly see my whole home internet going to a crawl, and see the newsd process is swallowing Gigabytes without any purpose. Really sucks because I'm on super expensive ($70/month) 1990s AT&T DSL - 6mbit/s with 150GB cap per month.


this bug has already cost me a few hundred $ in overages as AT&T gleefully rapes me for $10 every 50GB overage. Frickin pathetic excuse for a business.

GOOD LORD. I'm glad you mentioned that. We're on high speed cable, also bought the best modem there is. and yet recently I started noticing I was freezing up on online classes. My students got a kick out of it because my faces were apparently hysterical but it sucks to have to move to an iPhone when your expensive wifi won't work!


I bet it will tomorrow, though. THANK YOU for mentioning the internet crawl! I had not put two and two together!
