    I just noticed that a process called nsurlsessiond is downloading data from the internet at the maximum rate possible with my internet connection.

    I tried killing the process but then it came back after few hours. If I kill the process and restart the computer then it comes back again. My data quota is almost about to be over and data is expensive where I live :(.

    I have iCloud photo library and iCloud Drive enabled. However, I have not made any changes to any of those online storages (such as adding a new file or deleting a file from it).

    Please help me to find the root cause of this problem.

    Why would you kill a network process that belongs to macOS and is simply managing down-/uploads for iCloud or update related stuff and a couple of apps? It really isn't a problem unless you have a contract with restricted download volume. Let the machine do it's work and don't worry about it because it isn't a "problem".

    I have a limited data quota for the month. If it continues to download at this rate then my quota will be finished soon. And the other issue is that any other devices using the same internet connection cannot browse due to my mac eating up entire bandwidth.

    Does it stop if you turn off iCloud Photos?

    If you copy this code to Terminal nsurlsessiond will stop until you restart the computer

    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
