Nice. I tweaked a bunch of what you had, mostly to leave some things on you had set to remove. Huuuge noticeable improvement in performance.

How do I use this?

@jaduff Which Daemons did you leave as they are?

Does this only work in Sierra? I've been having tons of issues with launchctl on el cap saying it "Could not find specified service" even with the correct plist file.

I get the same as wallace-aph... Lots of "Could not find specified service" messages.

After running this I lost all Bonjour connectivity, no "shared" item in the Finder sidebar and I can't run screen sharing and nothing shows up under "Network"

@JGRvanR supposedly, to re-enable, just run the same script with load instead of unload :)

FYI , in 10.12.3:

root # /bin/launchctl unload -w /System/Library/LaunchDaemons/com.apple.AirPlayXPCHelper.plist 
/System/Library/LaunchDaemons/com.apple.AirPlayXPCHelper.plist: Operation not permitted while System Integrity Protection is engaged

☹️

@Brantone - Found a mention about getting around SIP to disable stuff here: http://apple.stackexchange.com/questions/255662/disabling-airplay-on-mac-sierra

@JGRvanN same here. I like the gains from running this, but breaking my LAN is a deal breaker. Anyone know what the Bonjour deps are?

NEW VERSION This is the version 2.0 of this gist. Just re-run it.

What's new:

• More services added
• Files are now renamed to .plist.bak so it won't run ever again unless you rename it to .plist
• It now requires SIP aka Rootless to be disabled to disable some services and to rename the files (you can reenable it after)

iTunes is not working anymore. I'm actually investigating the problem and I'll fix it asap.

Edit: The issue has been solved. It was "com.apple.AirPlayXPCHelper" that was causing the crash therefore it has been enabled again.

I just upgraded from Snow Leopard to Sierra and I can't believe all the connections Little Snitch is flagging. I don't use iCloud and don't have any iToys and don't "Social Network" so it's all wasted on me. Plus I don't like Apple spying on everything I do. Killing all these agents and daemons is a GREAT idea. Thanks!

BTW, there is a list of what a lot of these processes do at Triviaware

@sjc314: Glad you liked this script! Don't hesitate to share it and thanks for the tip, didn't knew this website!

On macOS Sierra 10.12.3 (16D32):
com.apple.Maps.mapspushd.plist Agent is named
com.apple.Maps.pushdaemon.plist

Other renamed or missing Daemons:
AOSNotificationOSX, FileSyncAgent.sshd, iCloudStats, mbicloudsetupd, laterscheduler

On macOS Sierra 10.12.3 (16D32):
com.apple.Maps.mapspushd.plist Agent is named
com.apple.Maps.pushdaemon.plist
Other renamed or missing Daemons:
AOSNotificationOSX, FileSyncAgent.sshd, iCloudStats, mbicloudsetupd, laterscheduler

I added the missing entry. I believe the missing daemons were removed but I still want this script to be compatible with older macOS versions such as El Capitan.

Thanks you,

Added (new?) com.apple.personad service to the kill list.

congrats, great work and easy to understand system patch. Have a side question: Could "little snitch" do the work too, i.e. just denying any communication from daemons? https://www.obdev.at/products/littlesnitch/index.html
BTW, I am not a rep from the company, just a heavy user, concerned about data privacy.

Thanks for sharing this.

I really like the intent here, but 2.0 breaks Calendar in 10.12.4.

Totally reproducible: disable, reboot, Calendar breaks. enable, reboot, Calendar works.

I also have spindump disabled. I tried reenabling, but Calendar still broken with 2.0.

Here's an error report. Advice appreciated.

Hello,

Thanks you. Regarding LS, you can, but the daemons will still be running and the buggy ones might eat your CPU/RAM/etc because they can't access the internet. By the way I noticed that Little Snitch was unable to detect Siri so.

Hello,

Thanks for reporting, maybe you should try to remove 'com.apple.CalendarAgent' (with quotes) from ./disable.sh and try again.

New v2.1: Added 'com.apple.security.keychainsyncingoveridsproxy' to the LaunchAgents blacklist because it was completely eating my CPU without doing anything useful. There is no documentation about this daemon but I suspect that it is used to sync the keychain with a remote server. Maybe using Cryptomator activated it as it uses local WebDAV and Java etc, I don't know but it happened since I launched it.

How's about a list of what these various processes do, so folks can make an informed decision about which ones they want to disable?

While true, as regards the junk Apple bundles with OSX, "bunch of #$!@" ain't the most informative of descriptions!

Hello @madranet, there are a bunch of already available informations on Google about the deactivated services.

Removing com.apple.CalendarAgent from the TODISABLE list brought Calendar back to life.

I'm still hoping to get Bonjour back.... but I'll see if I can live without it for now.

/System/Library/LaunchAgents/com.apple.SafariCloudHistoryPushAgent.plist - 'com.apple.SafariCloudHistoryPushAgent' when disable seem to speedup Safari, this a a macOS Serria 10.12.4

Somewhere in Agents to disable, plays havoc with the network lan & wireless , the Network does not show up in the Shared section of the Finder in sidebar, and even by other methods, if one can narrow this down to a list for active network from been disable would be welcome . Thanks for this excellent script & works a treat.

Created a GitHub account just to say thanks for this work, both tot he OP and the community!

I noticed a lot of network activity "phoning home" in radio silence, and wanted to try to shut it down in one fell swoop. Thanks to this, much of it is gone. I did notice that Messages will no longer start up, however. Does anyone know which specific service enable will bring that back, or should I learn to live without it?

thanks again.

Thank you! That's awesome

I'm worried about future updates undoing these changes. Why not use "launchctl disable" followed by "launchctl kill" instead of renaming the plist files?

It runs well on Sierra, make the device run very cool. But in El Captain, it makes accountsd raging and stuck at highest freq(but still cool).

Sierra 10.12.6. com.apple.security.keychainsyncingoveridsproxy overloads CPU. iCloud is likely the culprit.

I suggest adding in

# 1. Delete iCloud accounts, or remove com.apple.iCloud* agents
# 2. Disable SIP
# 3. Restart and run the script

Dang pwnsdx, you have really nice shell script style. How exactly does "${somearray[@]}" interact with a for loop and/or $IFS? Is there a difference between using an asterisk (*) vs. an at (@) when referring to a shell array?

Does anyone know of a resource where I can look each of these agents and daemons up?
I've been searching for them individually and certain items on the list aren't turning up any useful information.

Script editor is not able to run this script saying expected "

Awesome work but my games from mac appstore has stopped working, plz tell which parts i need to enable back.

Thanks a lot !!

First of all, sorry for my bad English.
So, is anybody found fix for empty Network in Finder after "disable.sh"? Stuck is that "enable.sh" does not revert functionality of Network :(

@AlexCommandor , which mac os do you use ?

Latest 10.12.6 (Sierra)

First of all, sorry for my bad English.
I did it!!! :)
I've found agent that could NOT be disabled - 'com.apple.identityservicesd'! Without it Network is always empty :(
But that is not enough - enable.sh has some errors! 'sudo mv' must be BEFORE loading agents and services, not after as is now. This is why enable.sh not works correctly. So, it must be as follow:

@pwnsdx I can confirm that commenting out CalendarAgent fixes the Calendar issue. Also, @AlexCommandor's sudo mv fix seems to work well. And @melMass's "easy to read" list is a really good suggestion.

How can I disable /System/Library/Services/AppleSpell.service ?

And how to run this script

Excellent work! Thank you. One thing I suggest to be added: nscurlsessiond. I am not sure which service or daemon it belongs to, but it keeps on pushing towards apple. Furthermore, this script could be enhanced by adding null routes or host entries for hot apple beacons to ensure decent protection for service revival. These beacons spotted already (just unverified):

32-courier.push.apple.com
33-courier.push.apple.com
api-glb-sin.smoot.apple.com
captive.apple.com
gsp64-ssl.ls.apple.com
gspe1-ssl.ls.apple.com
init-s0st.push.apple.com
init.ess.apple.com
lcdn-locator.apple.com
mesu.apple.com

You dont even need to diable SIP to add null routes (sudo route add 17.0.0.0/8 8.8.8.8 or similar) to dump all traffic to apple off. Many of them are actually hosted at Akamai or elsewhere, for those, a plain old host entry at /etc/hosts will disable them completely.

@melMass: even better, you don't need to escape the newlines within an array-variable assignment. (If you don't mind the backslashes, then you might as well just inline the array, a la for agent in 'blah' 'blah' 'blah'; do)

I'm not sure if this is related, but since I disabled all the services in this list (I also added spindumpd and tailsomething) my TimeMachine backups are painingly slow. Anyone with the same issue?

Something in the list of agents has taken out my finder/dock of my macbook pro. I suspect it was one of the last two agents but not positive.

thanks, i was checking why my mac mini was crawling like a tortoise and photoshop and capture one was unbearable. ran top and saw cloudphotosd, google that and reached here. Ran the script, killed the process and performance improvement is significant.
'com.apple.cloudphotosd' alone is using around 50% cpu all the time and poor Adobe gets a lot of blame.

Does this work fine with high sierra?

Please remove the link to Triviaware that is pretty nasty!

Can you tell me if it works on high sierra 10.13.3. and how you load this script (terminal) ? Best regards

I wonder if it is safe to also disable com.apple.GameController.gamecontrollerd.plist, maybe only if you don't play apple store's games ?

BTW thanks for your work, it's awesome!
Another question, where can I find documentation on the disabled services? The docs on the internet seems very poor...

Hi, I tried to determine which Processes/Daemons have to be left ON in order to have iCloud still running but all the rest turned off.
Any suggestions? I wasn't able to find out which of those thingies is responsible for syncing iCloud.
Many many thanks in advance!

I'm VERY interested in what philthepill mentions. I've been following QLab's advice and signing out of iCloud completely. But signing out of iCloud is a big deal, it's time-intensive and can cause corruption in my calendars & contacts. And I definitely don't want to permanently disable iCloud – I just need to temporarily disable it when using real-time music and video applications on stage. It would be great to be able to do this by disabling all the iCloud daemons and processes, with SIP turned off of course, instead of signing out.

In your disable/enable lists you have:
com.apple.iCloudUserNotifications
com.apple.icloud.findmydeviced.findmydevice-user-agent
com.apple.icloud.fmfd
com.apple.icloud.findmydeviced
com.apple.iCloudStats
com.apple.mbicloudsetupd

Do you think that's an exhaustive list, or are there other processes that would keep iCloud hogging the CPU when signed in?

Courtesy of QLab, here are couple more processes that you could add to the lists:
com.apple.photolibraryd
com.apple.notificationcenterui.agent

(NOTE: see my followup comment and fork, on 5/29/18 below)

Frecia, I have just found this: http://www.manpagez.com/man/8/callservicesd/ , then search for the daemon you want to have more info about. I found this page too https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man8/FDERecoveryAgent.8.html

Also, there is a question mark on the warning window of Little Snitch when a daemon tries to access internet, and it gives some info about what it is for.

And this page has some comments on some daemons http://tech.masterofsql.com/os-x/unload-disable-unwanted-agents-daemons-os-x.html

To this fantastic gist I've added sections (User Agents, "Library" Agents/Daemons) to disable/enable /Library/Launch* and ~/Library/LaunchAgents processes, which are specific to some real-time/music applications I have installed (substitute your own), but also include fairly common things like Dropbox and Google Chrome agents which eat up a lot of processing time. I also found all processes that are needed for iCloud to run, so now I don't have to actually Sign Out of iCloud (which can cause loss of Calendar and Contacts updates when you sign back in) in order to temporarily disable it.

Here's my fork:
https://gist.github.com/gopsmith/f216d8f41ea3b7d36d50a302e0a641dd

@pwnsdx THANKS FOR SUCH A GREAT SCRIPT and supporting El Cap! Hey, maybe it's just me but I would think that wrapping this in a GUI and allowing it to be "dynamic" (minus the SIP disabled ones) so that you can Disable a lot of stuff until it's needed via applet on the Menu Bar would be worth paying for!! Ie. Not using any itunes disabled, but when you need it, a simply click to enable and start. Oh course, I am out of my league on this but just a thought!

@pwnsdx Great stuff! Any chances to get this update for Mojave?

Has anyone had success with this on Mojave?

Yeah, since Mojave killing any of these daemons, unloading them and deleting the plist, results in macOS simply starting them up again. At this rate, I'm about to write a cron job to run every 30 seconds and terminate ****ing diskspaced if it's running. Getting pretty sick of being told that I'm running out of disk space and should buy iCloud every half hour because I've only got 13GB left.

it works in mojave for me after 'csrutil disable'... now i am running that on a vm... service does not comeback

Nice Job, Thanks!
Here a useful how-to disable SIP
https://www.macworld.co.uk/how-to/mac/how-turn-off-mac-os-x-system-integrity-protection-rootless-3638975/

Suggestion to add TouristD in you list
see: [https://apple.stackexchange.com/questions/294291/what-is-touristd]
https://apple.stackexchange.com/questions/294291/what-is-touristd

For Most Agents & Daemons I am getting error:

Could not find specified service
OR
/System/Library/LaunchDaemons/com.apple.apsd.plist: Operation not permitted while System Integrity Protection is engaged

The errors remains same even if I run the individual unload command with sudo.

I am running macOS High Sierra 10.13.2

what happened? when i installed this cpu usage jumped to 25%. Accountsd and rapportd going insane. and it wont stop.

it's objectively worse as before i ran it. after i re-enabled it, cpu usage DID NOT go down again

@debajyoti-xyz You need to disable SIP. See @helio-silva comment two above yours. Don't forget to re-enable afterwards.

Fantastic script! I modified it a little so the list of files is external, maybe it is interesting to anybody. Also, the daemos and agents are moved into /System/Library/LaunchDaemons.off and /System/Library/LaunchAgents.off instead of renaming them to .bak

APPLESHIT.DISABLE.SH

(You need to run it with SUDO)
