It has been noticed that all of my data packages "idleassetsd" consumed in one day 60GB first date, 2nd 30 and now running with 14GB, apart from this "nsurlsessiond" also consumes lot of data,
Is there any solution for this? this is very annoying after Sonoma update. altogether 193GB of consumed
iMac 21.5″, macOS 14.1
I had this issue on Sonoma. I used some basic methods to see the unencrypted content, and it was due to screen savers/wallpapers. The thing is, I clicked on them and ultimately did not use them, so it would seem that it triggered a background download of a ton of large high-def video files, regardless of the fact that they are no longer selected (and they continue to download). It doesn't bother me, as it seems to throttle itself down when other traffic starts to show up, so I haven't noticed any slowdown. I can see the video files consuming hard disk space (I took a snapshot, let it sit, took another, and compared the difference (please don't tell me that there are a million better ways of doing that. I was doing it for another issue primarily).
Edit:
I found a SQLite database of what it is downloading. However, I wouldn't mess with that without talking to Apple Support first.
You can run lsof if you are comfortable with the terminal. Here is what mine showed:
user@computer ~ % lsof | grep -i idle
Wallpaper 581 user 4r REG 1,4 481292429 5366651 /Library/Application Support/com.apple.idleassetsd/Customer/4KSDR240FPS/097CA871-A1C2-40F7-97F0-EFAABF555BBC.mov
If you prefer using a GUI, there is a great free program that basically visualizes the lsof output. The utility is Sloth.
Note that it takes "snapshots" and is not a monitor (although you can have it refresh at certain intervals).
Output From Sloth:
Note that in both cases, the output can be very large, which is why I used "grep -i idle" and searched in Sloth (I highlighted the search box in the top right).
I would not recommend blocking this connection in any way. The OS uses this to download many things. I would figure out exactly what it is downloading and work from there. Otherwise, you may have issues in the future when the OS is trying to download something that you do want, but it is blocked. Additionally, it will continue to try to connect and download and continue to fail, which would be undesirable.
After 1 Tb of lost internet I opened activity monitor and found out the problem to fix it my dad changed the wallpaper to a noodle that I’ve made ,and then the internet usage monitor dropped
Yes , That is not a solution though. again and again, this is happening for people after a new Update published
