kirger [04.06.2015 20:47] nsurlsessiond что это за подстава от Apple:
nsurlsessiond что это за процесс, который совместно с Сафари на Yosemite выжирает такой дорогой для меня, я сейчас на сотовой связи, трафик?
Пока выход нашел один, не пользоваться Сафари. Однако не понятно зачем это nsurlsessiond? Steps [04.06.2015 20:55] :

О спасиб, сволочь ограбил меня на 4 гига Водафона 🙁 kirger [05.06.2015 23:42] :
Степс, или может кто еще знает, что и где можно выключить? жрет трафик безбожно, работает только майл, сафари и адиум. Steps [05.06.2015 23:54] :
Кирыч, я посмотрю. Пока просто руками через Мониторинг убивай процесс. Или LittleSnitch поставь, он исходящий трафик обрежет. kirger [05.06.2015 23:57] :
Андрюх, может я и зря паникую, сейчас посмотрел мегабайт в минуту, может это и нормально? я просто никогда не считал, а сейчас приходится 🙁 Steps [06.06.2015 00:04] :
Много. Я в ночи перегружусь в 10.10, она чистая у меня, на ней вообще ничего нет кроме адобовских триалов, и засеку. kirger [06.06.2015 00:18] :

Вещь, только знать бы какие процессы обрубать, а какие нет. Не хакер я уже ;-( однако стало в половину меньше. вру, 20 минут, трафик 1,5 мб
Степс ты меня спас. Steps [06.06.2015 00:27] :
А на неё надо немного времени потратить просто, на гуглёж. Ну вот то есть всякие Ромки и так знают процессы по именам, а нам гуглить нужно. Появилось предупреждение — смотришь, кто это. Если нажать на адрес, Снич вообще выдаёт список с портами вместе. Там системное обновление наверняка в паранойю впало и постоянно в Стор ломится, сам софт проверяется… Это исходящий, да, но на него ответы приходят. А у тебя софт легальный, следовательно, ничего не запрещено нигде, вот проги (и системные службы) и веселятся от безнаказанности. kirger [06.06.2015 00:28] :
а я все подряд стал отключать, кроме майла, адиума и сафари [Ответить]

Как узнать, что загружает nsurlsessiond

Я отключил все файлы iCloud, и, похоже, что-то еще использует его. У меня нет обмена фотографиями и синхронизации фотографий между моим Mac и iPhone. И я выключил все, что мог. Но все же nsurlsessiond загружает более 400 МБ каждый раз, когда он запускается; который иногда запускается при перезапуске системы.

Я сделал образец процесса; но я понятия не имею, что это значит.

Этот демон можно вызвать из многих источников.

Я не нашел простой способ обобщить вещи, но поскольку он работает в очереди на загрузку или загрузку вещей, я предполагаю, что у вас есть работа, которая отключается.

Вот несколько способов выделить деятельность в вашей системе:

Это позволит вам следить за вещами и видеть, какой из нескольких демонов nsurl работает, когда вы измеряете 400 мб передачи. Вы также можете получить дамп активности системы с помощью sysdiagnose nsurlsessiond

Если вы определите, что это действительно документы iCloud, вам, скорее всего, понадобится brctl log -w , чтобы наблюдать за этой подсистемой вместо мониторинга рабочих потоков, сделать подъем.

В моем случае я обнаружил, что:

При резервном копировании чата WhatsApp (на iOS — iPhone) в iCloud он копирует резервную копию на каждую машину, использующую iCloud. Резервная копия помещается в скрытую папку на моей машине (OS X 10.11.4), она находится в

/Пользователи /UUUUUUU /Библиотека /Мобильные документы /57T923XXXX

WhatsApp /Accounts /NNNNNNNNN /backup

, где UUUUUUU — мое имя пользователя, а NNNNNNNNN — мой номер телефона.

К сожалению, файл резервной копии для носителя находится в одном огромном архиве (мой -> 560 МБ), поэтому каждый раз, когда WhatsApp выполняет резервное копирование, файл WHOLE повторно загружается из того, что я вижу. Это то, что делает nsurlsessiond.

Если вы запустите команду brctl log -w, упомянутую выше, вы увидите что-то в этих строках:

Удаление документов WhatsApp (например, резервных копий) через консоль управления хранилищем iCloud в iOS или Mac OS X удаляет файлы из папки «Мобильные документы», и после этого больше нет активности от nsurlsessiond.

Надеюсь, что это поможет.

Это был действительно полезный пост:

Для меня это было «автоматическое обновление» из App Store. Переход к «системным предпочтениям — магазин приложений — отключить обновления», сохранил сотни мегабайт в день в полосе пропускания. (и сделал все быстрее)

Для гуглеров, которые просто хотят остановить использование полосы пропускания, выполните то, что сделал OP, и отключите службы, которые могут вызывать проблемы:

ICloud

Системные настройки -> ICloud
Снимите флажок:
- iCloud Drive
- Фото

Предложения Spotlight

Системные настройки -> Spotlight
Снимите флажок «Предложения по Spotlight»

Если вы обнаружите что-то еще, связанное с полосой пропускания на вашем компьютере, оставьте его в комментариях, и я добавлю его здесь.

Как узнать, что скачивает nsurlsessiond

Я отключил все диски с iCloud, и, кажется, что-то еще использует его. У меня нет обмена фотографиями и синхронизации фотографий между моим Mac и iPhone. И я выключил все, что мог. Но nsurlsessiond по-прежнему загружает более 400 МБ при каждом запуске; который иногда вызывается перезапуском системы.

Я сделал пример процесса на нем; но я понятия не имею, что это значит.

Этот демон вызывается, и для загрузки служб требуется вызов из многих приложений и многих служб в macOS. (И iOS, и ТВ, и WatchOS)

Я не нашел простого способа получить сводные данные или статистику из диспетчера сеансов, но, поскольку он работает в очереди для загрузки или выгрузки, я предполагаю, что у вас есть одно или несколько заданий по времени.

Вот несколько способов выделить активность в вашей системе:

В первом перечислены открытые файлы и сортировки для совпадений «nsurl». Второй перечисляет все процессы и сортирует снова. Третий список активности файловой системы.

Это позволит вам отслеживать вещи и видеть, какой из нескольких демонов nsurl работает, когда вы измеряете 400 МБ передачи. Вы также можете получить дамп системной активности с sysdiagnose nsurlsessiond

Если вы решите, что это действительно документы iCloud, вам, вероятно, придется brctl log -w наблюдать за этой подсистемой, а не отслеживать рабочие потоки, выполняющие эту работу.

В моем случае я обнаружил, что:

При резервном копировании чатов WhatsApp (на iOS — iPhone) в iCloud он копирует резервную копию на каждую машину, которая использует iCloud. Резервная копия находится в скрытой папке, на моей машине (OS X 10.11.4) она находится в

/ Пользователи / UUUUUUU / Библиотека / Мобильные документы / 57T923XXXX

WhatsApp / Аккаунты / NNNNNNNNN / backup

папка, где UUUUUUU — мое имя пользователя, а NNNNNNNNN — мой номер телефона.

К сожалению, файл резервной копии для носителя находится в одном огромном архиве (у меня размер> 560 МБ), поэтому каждый раз, когда резервное копирование WhatsApp, файл WHOLE повторно загружается, насколько я вижу. Это то, что делает nsurlsessiond.

Если вы запустите упомянутую выше команду brctl log -w, вы увидите что-то вроде этого:

При удалении «документов» WhatsApp (т. Е. Резервных копий) через консоль управления хранилищем iCloud в iOS или Mac OS X файлы удаляются из папки «Мобильные документы», после чего nsurlsessiond больше не выполняет никаких действий.

Question: Q: Catalina high CPU usage (nsurlsessiond, WindowServer, trustd)

My Macbook Air has been running smoothly and without issues for 7 years, then I update to Catalina and boom! the fan is going crazy from time to time. When looking in Activity Monitor, it seems that the top CPU-using processes are

Even with all apps closed (including ones that usually live in the menu bar). I’ve also logged out from all the Apple bloatware (iCloud etc) which I don’t use anyway.

As absurd as it sounds, the only thing that seems to help (sometimes) is to quit Activity Monitor. other times I just shut it off and go use my Macbook Pro instead, which is running Mojave.

Any ideas what could be causing this?

Similar issue on my 27» iMac end 2015 after migration from El Capitan to Catalina. According to activity monitor the process «nsurlsessiond» (of user «_nsurlsessiond») produces about 62% CPU load, there is only minor usage of network, hard disk, and memory.

Similar issue on my 27» iMac Late 2012 after migration from El Capitan to Catalina. According to activity monitor the processes: «nsurlsessiond» (of user «_nsurlsessiond») produces about 62%, trustd — 40%, syslogd — 33%, launchd — 21% (of user «root») CPU load, there is only minor usage of network, hard disk, and memory.

I had the same thing with my mid 2012 Macbook Pro. It was running painfully slow on Yosemite (yes I was really that far behind) so I upgraded to Catalina, which pretty much rendered by Macbook useless due to the high CPU usages of nsurlsessiond etc. I also, very foolishly, did not realise that Catalina no longer supported 32bit software. This meant CS6 and few old game no longer run.

No idea what causes the nsurlsessiond etc. — I tried several time to resolve the issue and searched the apple forums for advice but to no avail. In the end I came to the conclusion that the hardware on my Macbook Pro is not sufficient, even though it’s listed as compatible. I’ve completely wiped my Macbook and reinstalled El Capitan, and it’s running faster than ever (and CS6 works fine). Obviously El Capitan is unsupported so there are security risks, but I can’t afford an upgrade at the moment so I’ll take the chance.

Hopefully Apple with issue an update to fix the excessive CPU usage as it does seem to be affecting a lots of people.

I had this same issue or nsurlsessiond process and trustd process taking majority of CPU time/ cycles in my Mac Mini after upgrading to Mac OS X Catalina. What fixed issue for me was to reset PRAM/NVRAM.

«Reset PRAM/NVRAM – Restart your Mac. After it is turned on, as soon as you hear the startup chime, press Option, Command, P, and R keys together and hold them until the Mac restarts again.»

Hope this helps some one looking for an answer.

Resetting PRAM/NVRAM worked but only for a short time. maybe an hour or less then I heard my fans going nuts and CPU temp shot up to 150 degrees (smcFanControl to see temp) and Activity Monitor was showing nsurlsessiond was back at 60% of CPU usage. BTW, I’m on a mid-2012 MacBook Pro 15″ Retina. I read lots of folks reinstalling a fresh OS but I’m trying to avoid doing that. I found the following and so far it’s working:

(Main thread) nsurlsessiond, trustd, syslogd high CPU

I read through the entire main thread (linked above) and specifically followed these instructions:

Question: Q: nsurlsessiond — what is this and why does it use alot of data?

I was in a public library, uploading to my dropbox account, and all of sudden my network speed indicator/ montior showed heaps of download and fast too.

but i was not downloading anything.

I was upping to my dropbox account.

In activity monitor i noticed this service was operating «nsurlsessiond»

What is this service?

In my connection alert it tells me nsurlsessiond tried to establish a connection to apple-dnld.vo.llnwd.net on TCP port 80 (http)

Secondly, i was using my own wifi, and saw this nsurlsessiond service consuming heaps of data. Again I was upping to my dropbox account. About 1gb this time.

Now I have blocked communciation to «nsurlsessiond»

What is the impact of blocking such communication?

please see details of service in screenshot

Now after this experience, I am wondering is it apple policy to have communication from our macbook’s to somwhere without us knowingly allowing it? I thought apple was respective of our privacy, or has this changed?

thankyou for your help and time.

This is a system process used to perform network communication. It is used by both Apple and 3rd party software. Your system will not function properly if you disable it.

Apple only has control over its own software and any software sold through the Mac App Store. You can be reasonably confident that any software your downloaded via the Mac App Store will respect your privacy because of Apple’s sandboxing architecture and review process. There is no such guarantee if you download software from outside the Mac App Store. However, this is a sensitive topic on the internet and privacy issues are usually quickly identified and corrected. This applies to both Apple itself and 3rd party software. In most cases, if you are using reputable software, there is nothing to worry about.

Do you see this activity only when using Dropbox?

Apr 29, 2015 9:25 PM

i couldnt say. it was just that i happen to be only upping, to dropbox, and then saw downloading on the monitor.

that was triggered as odd.

i rarely look at what services are going on. only if my macbook slows down or something else odd.

in both cases i was only upping to dropbox.

i dont do alot with my macbook, other than upping to dropbox laterly.

thankyou for your thinking and help.

I have the same process acting weird as well as two others called «mapspushd» and «nbagent» application that say they want to connect to apple.com; however in doing so this makes the mac completely still nothing happens except pinwheel torture.

I’d like to bring attention to this thread Re: Slow start and Mac as I believe the core problem in most of these Yosemite posts is the same.

Thankyou for your time and effort. I have been busy troubleshooting. It appears this surge of network activity (and data transfer) from this process, nsurlsessiond.. was the start of my MacBook pro starting to have performance Issues.

I noticed these performance issues when I was using Pathfinder, Dropbox Sync or OSX Mail. For example, my file transfers (move) between mac and my external over local home WIFI is very good. Often many GB at a time. Then I had this transfer for 30000 files but only 130mb in size that took 10hrs! I stopped it 3 times, to try and get a better transfer rate, then just let it run thru the night. It completed.

So something is not happy for my macbook, I have concluded.

Mac OSX
1. Checked the Console Logs, and heaps of items mentioning de.novamedia. nmnetmgrd.. launch2net.. These all related to a vodafone USB installed app for the USB mobile broadband that never worked. So uninstalled and deleted via terminal anything related to this. Followed Sleep — OS X 10.6.8
2. Remembered by MacBook for the first time has been forced into sleep mode as I was on free wifi and ran out of battery. When I rebooted it did not do it correctly (both times) as the Clock was not set correctly. Well my setting is for check on internet time asia, but when I rebooted I had no internet, so silly think does not remember the date from before loosing power. I connected to internet and fixed this. Recurring issue. My setting for power is never allow this computer to sleep as wierd things happen with returning from Sleep Mode so I no longer trust it.
3. Checked Console Logs, and many many system logs that show event, wakeups (microstackshots only). No idea what this means.
4. Checked Console Logs, and had heaps for opendirectoryd (Apple’s Directory Services). LIke it was so busy writing these logs..there were many. I checked Apple Support Forum and essentially I got the message, some node, is out of whack.. and my lovely MacBook cannot find something first try. So I popped into Disk Utility and ran Verify Permissions (there were like 5 to repair, so clicked Repair) and the other check routine (?Verify Disk). Received the all good. So no sure how this node thing.. happened.. if its still there.
5. Then I remembered I had downloaded so new utility OSX Apps and there were many so had created a sub-directory under Applications/Utilities. So this is non-standard. Removed this and moved all the Apps under /Applications
Email App — I rebuild my Email mailbox (option in OSX email, Rebuild). Not sure if it works, but I tried. Next step, will see if I can delete entire mailbox off macbook and simply resync to Gmail. it is 5GB, 1 mail account, many many folders and many emails.
Dropbox Sync App — In reading the Apple Forums, I read, often Dropbox Sync is the problem for this enormous amount of log activity. Then I remembered I upgrade to v3.4.4 for Dropbox Sync very recently. And these issues only started recently. And then I had a crash and crash report is called, garcon_2015-05-05-144442_computername.crash. And then somehow when I was trying to fix another dropbox issue (dropbox-daemon runs on seedbox and links to same Dropbox Account that is sync to macbook), I managed to unlink the Dropbox Account to Dropbox Macbook. So I relinked and everything looked ok, but maybe i messed it all up. Sadly Dropbox Support dont respond and no replies in forum either. (Maybe too popular).
PathFinder (File Browser App) — Send 2 sample process to App Support of Pathfinder. Awaiting

So now, current settings regarding connections allowed/blocked

Allowed (stopped blocking) nsurlsessiond, but I do not like how it uses data on my mobile broadband. If Apple need to check something, I really prefer they give me option, to check while on WIFI as mobile broadband is so expensive. or if they need to check on a public WIFI, they ask as I do not want to be downloading stuff that I do not realise on a public WIFI. I also see this nurlissueID using data is an issue for others (What is Apple’s fix for the nsurlsessiond issue of uploading data and hogging bandwidth?). So I have used the Feedback link to inform Apple, and when I am on mobile broadband block connections I try to remember to block nsurlsessiond manually.
Blocking the other one mentioned in post, mapspushd, as it errks me all this location information about me being transmitted. I don’t use maps

Console under Library/Logs/Crash Reporter, I am seeing many for com.apple.networking.discoveryd.log, that I dont know what means. I recently added the app, MacFusion and it is having trouble with time-out before authenticates me, although passcode correct. So maybe it has something to do with this.

May 6 07:19:00.359020 localhost discoveryd_helper[258]: Basic RemoteControl com.apple.discoveryd_helper Starting XPC Server

May 6 07:19:00.359535 localhost discoveryd_helper[258]: Detailed RemoteControl com.apple.discoveryd_helper XPC connection 0x7f9c83d00a20: start (pid=72, not root)

MBP fan does do its churning thing when the mac is really working and for no reason. I have not reset SMC yet, as in prior times before FRESH install of yosemite osx, this I ddi and nothing improvement. To reset SMC, I follow Resetting the System Management Controller (SMC) on your Mac — Apple Support
I do not know where else to troubleshoot, so I wait and check the Console for unusual logs. This is all I can think off.

I need to have Dropbox Sync running alot in next few 3 days. So I will record times.

Any other suggestion of next troubleshooting steps? Any particular log to log-out for in Console?
