Switch on and off nsurlsessiond on Mac OS

If you use iCloud services, you may have noticed that sometimes your bandwidth is fully saturated by processes called nsurlsessiond or nsurlstorageid; these services take care of syncing your files, photos or contacts with iCloud. It happens that sometimes you can't count on large bandwidth and this is a bit annoying. This is why I created this simple script to activate/deactivate iCloud nsurl* processes.

#!/bin/bash function cloudOn { launchctl load /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist launchctl load /System/Library/LaunchAgents/com.apple.nsurlsessiond.plist sudo launchctl load /System/Library/LaunchDaemons/com.apple.nsurlsessiond.plist sudo launchctl load /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist } function cloudOff { 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 } if [ -z "$1" ]; then echo "Usage: $0 on | off" elif [ "$1" == "on" ]; then echo "Switching cloud on.." cloudOn elif [ "$1" == "off" ]; then echo "Switching cloud off.." cloudOff else echo "Invalid argument" echo "Usage: $0 on | off" fi

Download this code, save it on a file and chmod +x cloud.sh.

To disable nsurl* services just run: ./cloud.sh off.

To enable nsurl* services just run: ./cloud.sh on.
