Nsurlsessiond ISNT GOING AWAY

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

You could use Little Snitch to block it's antics. Sorry it isn't a real solution, but it could stop it in the short term.

Another option may be Icefloor, possibly with Murus to do the same thing.

I think you may want to consider a filter that can sit between the outbound traffic & your wifi/ wired network.

I hear good things about Sophos UTM (used to be Astaro gateway).

I just can't get it working on a Mac that I tried, it is free for home use but the Sophos site is insanely complex.

That should allow you to stop clients downloading all the Apple updates etc, but it is involved.

Bananaporcupine thanks for raising this - we are also in rural Australia and run businesses from home - this nsurlsessiond problem is chewing up our plan so that we go through our internet quota in days rather than a full month. We cannot buy more data as we have the maximum plan (which costs $110 for 15gb) - we manage our use very carefully and this is a real blow and will hurt us badly. Apple need to understand that much of the world still doesn't have access to massive internet plans.

I don't know if iCloud is the only use of this process, but many users have been complaining about the recent addition of Photos. It will upload all photos to ICloud. That may be many GB's of data.

Ensure that is turned off if you are on a restricted network. Otherwise you may simply be fighting the inevitable - uploads will keep resuming since it is required by the iCloud settings.

Good luck with it

You are a champion - there were a lot of conflicting fixes thanks! We used the Terminal fix and hopefully Apple will fix the problem soon other wise we will need to go the Littlesnitch route.

Thanks again.

The 'fix' is a bit of a kludge IMO.

launchd has the ability to permanently disable jobs, the -w flag will do that. So you can run the command once & forget about it (updates may undo the change).

It's unclear to me how essential this process is for other OS features, but the correct way to disable services is in the manual.

https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man1/launchctl.1.html

Obviously disabling Apple services can cause other issues, so bear that in mind if things fall apart in odd ways 🙂

Thanks - we didn't do it lightly but unfortunately we have no choice. Without doing it we run out of data with no options to increase and therefore we cannot work. Unfortunately that is the situation in rural Australia.

Just clarifying though - My understanding is that restarting my Mac will refresh things and eliminate the Terminal command?

'launchctl unload' will remove a job untill next boot

The same command with an extra -w flag will set an entry in a db to permanently block that from loading on boot.

# temporary

launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist

# Permanent

launchctl unload -w /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist

thanks

I too have experienced this problem and it blew out my download cap with iiNet. Some third party software suppliers also use nsurlsessiond. Do you have the adobe creative cloud programme installed? I have some evidence from the way my IMac and laptop have been operating that it may have something to do with creative cloud and I wondered if anyone else has experienced a similar situation.

Here we are a year later with the same problem which I had been battling for days until I found your solution. I pasted it into my Terminal and BINGO! I had back my full bandwidth again instantly. As our service is only 2mbps carrying about 12 devices this was a very important repair. I still have to keep various Photos up/downloads off ICloud Drive while working (I will switch it back on when I take a few days off so that it can sap the Internet uninterrupted until our thousands of photos get synced). Anyway, thank you!
