Your Mac is probably eating your Internet bandwidth (and you don’t know about it!)

Last week, my monthly quota with my ISP got exhausted much before the cycle got over. Yes, I was FUP’ed.

60 GB isn’t a lot when you have a 20 Mbps hose, but I seldom hit that mark at home considering I travel a lot, and home broadband is one of the many internet connections that I use to stay connected / work.

Driven by curiosity, I logged on to my account and noticed that I had used over 6 GB of data the day before. That came in as a surprise because I had barely used the internet that day — no big downloads and minimal music streaming — even though my computer was on for several hours.

I almost freaked out, thinking that someone else is latching on to my home WiFi network. Little did I know, it was Apple, not Pandey ji.

The next day at work, we were chatting about how the new Mac OS X El Capitan is a 6 GB download, and I offered my colleagues a USB drive that had the installable on it.

The conversation went on and our Rocket Singh mentioned about this creature called nsurlsessiond that he found is always on and keeps sucking the bandwidth. I looked up at the Activity Monitor (under the network tab) and boom! This little daemon was eating up a big share of my quota, and it didn’t seem to stop, no matter what! Here’s how it looks,

nsurlsessiond

A quick search and I found various hacks to stop this. The good news is, you don’t need any of those, nor do you have to read through the entire thread. Just check your spotlight preference and turn off Spotlight Suggestions and Bing Web Searches, that’s it. Don’t forget to click on the “?” at the bottom right corner of the Spotlight Preferences window.

Thank me later. 🙂

  1. I’ve spent dozens of hours on this. This insidious little hog was bogging down my internet so bad my provider was scheduled to come out for a second modem replacement to try and solve it. Finally figured out it was my laptop. Thanks. You saved the day!!

  2. I am not able to resolved my issue..
    I have turn off Spotlight Suggestions and Bing Web Searches, but still nsurlsessiond is eating internet bandwidth…

    I have even sign-out from icloud from my macbook

    Please HELP….

    1. This terminal script will kill the process:

      #!/bin/sh
      launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist
      launchctl unload /System/Library/LaunchAgents/com.apple.nsurlsessiond.plist
      sudo launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlsessiond.plist
      sudo launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist

      … but has to be done after every reboot.

      1. little snitch control allow to control any income and outcome connection.
        impressive the amount of process ask to connect to internet

  3. I installed macOS 10.12 (Sierra) on my macbook white. Now insurlsession d is also eating my data. I turned off Spotlight Suggestions but there is no Bing Web Searches. Still chewing data. I then turned off all categories (yes, I did click on ?) to no avail. What now?

    1. If you are using iCloud Drive you should stop — that is one of the prime culprits. Photo sharing should be checked, also. “nsurlsessiond” is kind of the director for all those background cloud processes, and some of them presume unlimited broadband.

  4. thanks alot sir .
    your terminal command was really helpful ..
    Is it anyway we can disable it permanently?
    please revert on email if possible

  5. I may be completely wrong here, but here is what is happening to me – you may not need to do anything, or at least this may help better explain what’s happening. I believe this process is simply the process by which iCloud and iPhotos update the files from the cloud. For example, I have been having a horrible time on my home network with slow speeds. Then somehow I realized when I turned off the wifi on my MBP my speed issues were resolved on the other devices. Thanks to this thread I realized it was the stated process running. Well after two days of troubleshooting it suddenly dawned upon me that we were on vacation and I took lots of photos and videos on my iPhone. Once I allowed the process to finally finish, suddenly my internet connection “problems” went away. It really wasn’t a problem at all, it was working as it was supposed to work. Just let it finish doing it’s thing… of course you could momentarily kill it, but then your files won’t be up to date from the cloud. Hope this helps someone…

  6. I just stop using iCloud drive, the moment I disable it, the activity of nsurlsessiond stops.
    you can do it on system preferences/icloud

  7. With Little Snitch, I use TripMode to control incoming and outcoming connections with my Mac, Result: no more warming up processor, no more loss of Data…

  8. My Mac has been sputtering along and I was getting crazy overage charges for my bandwidth. I’ve been searching for the solution and it’s alluded me until today. You are the MAN Pravel!!!!!!!!!!!
