I recently noticed that a process called “nsurlsessiond”on my MacBook was taking up almost all of the bandwidth available and kept downloading data which prevented me from accessing the internet properly.

When I researched about the issue, I found that I wasn’t alone and many faced this problem.

So tried out some methods and it seems to be working fine.

Some suggest that you can turn off the iCloud Photo Library Sync for one and this could solve the problem. You can do this by going Photos app, go to preferences, and choose pause for one day.

This will stop the transfer for a day, and you can enable when you want to.

I found a little shell script posted on the Apple Support Community to stop the nsurlsessiond process until the next reboot.

!/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

Even if you do not understand shell scripts, you need not worry. You can just post the four lines above in the terminal program.

Sudo commands require you personal password, just so you know. And when you type your password, it might appear as though nothing is happening on the terminal window. You can just type the password when prompted and hit enter.

You can also try turning of Spotlight search suggestions and bing search suggestions in order to save data. However, I don’t prescribe this one i f you’re like me who uses the search very often and do want suggestions.
