I get the message "com.apple.extensionKit.errorDomain error 15." on my MacBook Pro macOS Ventura when I try to access Internet Accounts.

Hi!

I was having this problem (and some others) on my primary admin User account. I finally figured out a simple fix I hadn't seen anyone else mention.

Solution Summary

I created a NEW USER ADMIN ACCOUNT. After I created the new admin account, I realized it was NOT having the same problems as my corrupted original admin account.

Problem Cause and Symptoms

The problems I'd been experiencing on my original admin account were caused by me messing around with some permissions and making a broad change by accident across my Users folder. Here are some examples of problems I'd been experiencing to see if you can relate:

• ExtensionKit Error 15 when going to certain areas of my Settings
• Unable to open certain applications - in this case Microsoft Word
• Finder essentially did not work; kept hanging
• Chrome wouldn't work
• App Store - wouldn't download apps; got stuck on preparing to download.
• As I type this, I think most of the applications that wouldn't work were open at the time of my change.
• Everything that WAS working was running so slowly, you'd think it was Windows ME running on a 1989 computer; it was bad.

Attempted Repairs

• Didn't Work: Messing around even more with the settings (don't do this, you'll just make it worse and go mad)
• Didn't Work: Tried using diskutil to repair permissions in the Terminal (if you don't know what this is right now, don't try to figure it out)
• Didn't Work: Tried Disk Repair utility in regular mode, safe mode (restart and hold down shift), and recovery mode (restart and hold cmd + r). Please note there are several ways to load recovery and safe mode for different purposes. The keyboard shortcuts I'm sharing here are just examples; please check Apple Support docs for more info.
• Didn't Work: Tried a reinstall twice; still had errors in main account.
• Probably would have worked if I'd have tried it: Calling Apple Support, who was very helpful and recommended an erase & reinstall to get computer back to default. I am just stubborn and didn't want to try this until very last resort so I didn't have to setup everything...plus I wasn't confident everything was backed up (just my important stuff, which I guess is what matters).

Solution:

1. I created a new (2nd) Admin account.
2. I did one more basic reinstall in Recovery Mode without erasing anything through Disk Utility.
3. When the reinstall completed, I logged into my normal admin account, check to see if it was still screwed up. It was, so I logged out.
4. I logged into my NEW Admin account and realized the problems were not happening there. I was able to access all settings, apps, etc. without any errors.
5. I began comparing the permissions (right click, get info, view permissions) between the two admin accounts for Users/YourUserID$/Library and began to see that the permissions for my OG Admin were totally different. (Not part of the solution, but in case you wanted to verify this is what was screwed up in your situation.)

Choose Your Own Adventure Wisely

With all of this being said, now I am still at the point where I need to decide what to do...and where you need to figure out what you will do if my solution works for you.

Options for Next Steps:

• Continue wasting time trying to fix main admin account (not recommended): If you can figure out how to do this, please let me know.
• Use the Opportunity to still access my files wisely and follow Apple Support's instructions (recommended): Consider this a miracle and use the opportunity to back up everything I wasn't sure I'd backed up before when my main profile got messed up, and listen to Apple by doing an erase and reinstall in order to restore computer back to its default. Please note there is a special way to do this. Find the documentation and follow it! This is not just a reinstall; it's an erase and reinstall.
• Keep using the new admin account and keep or delete the original admin after replication (?): I don't even know if this is a good idea! I don't know what would happen if I deleted that OG account or if it's even possible. It doesn't seem like I can even delete it using the new admin account.

Option 2 is probably the best one. Count your blessings, save your stuff using the 2nd admin account, and start over from scratch.

Don't waste time going through error logs trying to fix 8 billion little errors unless you REALLY know what you're doing, have that kind of time, and find it absolutely necessary.

Please note that my new admin account was able to have access to all my apps and files because of how I'd setup the original admin account. I had installed apps so that they would be available to ALL USER ACCOUNTS. And I also have permissions for the new admin account so that it has access to my old admin account's files. I will not be elaborating on how to do this.

If you have the same problem I just got done dealing with, I wish you the best of luck and godspeed. I hope my solution helps some desperate folks out there, especially those who forgot to do a proper backup.

Try this. It worked for me...

1. Go to settings;

2. Search "Wi-Fi"

3. Click "Details"

4. Slide "Limit IP Address Tracking" to OFF.

5. Close settings and try operation again.

I was grateful for Old Toad's advice, but I followed it to no avail. An Apple saleperson then told me that my problem was almost certainly caused by my attempt to migrate my data from a recent Mac with a Silicon processor to a somewhat older one, running on an Intel chip.

He said such transfers would inevitably cause conflicts. I'd be interested to know if this is true, and if it is I feel that Apple ought to warn people of it. That would certainly have saved me a rather long day of hassle.

Another element which may or may not be significant is that I didn't reset the Intel Mac before transferring my data to it.

Needless to say, the whole business has been a bit expensive, as I found myself buying a new machine, something I hadn't intended to do quite so soon.

Just opening up the Migration Assistant seemed to kick start this problem for me. I bought a new M1 mac mini and was going to transfer data from my M1 macbook pro, so the difference in the chip tech is definitely not a fair explanation. The thing is, I DIDN'T even transfer anything, and the problem is now on my mbp. And I can't access the network settings.

After my e-mail was basically blocked by the problem, I didn't try to reinstall the system on my Intel MacBook Pro. As I urgently needed an operational Macbook to travel, and had in any case been planning to buy a new portable after my trip, I simply rushed down to the AppleStore to make the purchase earlier.

I successfully transferred my data to the new MacBook via a TimeMachine backup taken from the Mac Mini, rather than using Migration Assistant. I therefore have no idea whether my problem was caused by using Migration Assistant.

Sorry not to be more precise, but I was doing things in a hurry, and this business is way above my technical abilities!

My version of the error comes in the form of a repeated request to "Do you want the application “java” to accept incoming network connections?" When I went to network > firewall to allow Java to accept incoming connections, it threw the com.apple.extensionkit error. Agree, my system is essentially bricked until this is solved.

I'm having the same issue on my desktop, laptop, iPad and iPhone after the latest updates for iOS and Monterey. No help from any of the articles and solutions suggestions from apple support. Devices freeze and have to literally shut them down with the power button.

In my case it was SonarQube, which is a quality assurance tool for computer programmers. It was running a Java process that began on startup, so rebooting was restarting both the computer and the pesky process.

I guess the suggestion I have is to check what's starting up when you start up. The process that started on startup was running a SonarQube daemon that restarted the process every time I killed it with "kill -9 xxxx".

From what I can tell from the comments, I'm not so sure it's the same thing causing it on all of our computers. That's why I said your mileage may vary, ha ha?

Hallo, hat das Problem jetzt wer lösen können? Ich habe das selbe Problem und bekomme den Fehler nicht weg!!

Hello, has anyone been able to solve the problem now? I have the same problem and can't get rid of the mistake!!

Since the 13.3 update the screen saver doesn't work anymore and when I go to the settings the settings are frozen and I'm getting this:

Einstellungsfehler - Der Vorgang konnte nicht abgeschlossen werden. (com.apple.extensionKit.errorDomain-Fehler 15.)

Does anyone have a fix or should I wait for 13.4?

I have been in deep trouble on this since having restarted after macOS 13.3.1(a)

Installation completed seemingly without a hitch.

Duh, no.

Upon the very first restart after the 13.3.1(a) update when the system loads itself, a scratch came into my view. Most likely outdated driver(s) in /System/Library/Extentions/ with .kext extension dose some harm on my machine, MacBook Pro 15” 2017.

There I have been experiencing Touch Bar lit off so I have no control over the keyboard lights, volume, etc. Especially troubling is Toch ID. FYI, safeboot dose right thing and troubles gone away.

And all my passwords stored in the keychain completely gone. I can not get mail messages because having not been successful in logging intoIMAP servers including Apple, Google or whatsoever.

All Cloud services are denied of accesses.

I believe getting rid of the troublesome driver kext files. But the problem is I don't know which to stay and which to go.

I’m having the same issue. My emails are no longer searchable in the apple mail app, which means I can no longer work. I have RE built my brand new Mac book pro and still getting the same error. This is so frustrating. Ever since the lastest upgrade to Ventura and 13.3.1. Apple needs to fix ASAP and fix the mail app!

Hi ScOtRa00,

Well, re-installing from scratch, i.e., clean-install, and go some updates are often told a better way. The next best thing is use the help of TimeMachine's backup.

You know many application support files, and drivers had been cumulated over the years, and in most cases, you can not even find installers et al for the applications you have been counting on. So, in a sense above solutions can be an overkill.

You open System Settings -> General -> Information -> macOS pane -> rightmost lies an information mark with "i" in a circle. You can click on it. Then a dialog appears that gives you the choice between staying with the current version of macOS (with some updates installed) and getting rid of the last update that seems the culprit. It deed wonderfully worked on me. The problem is I am still facing hazardous malignant outside attacks that use the macOS' fatal flaw because you are now without the latest and greatest update unpatched.

my two cents.

"ExtensionKit Error 15: I resolved it. Took some digging in the Terminal window with the ‘ps’ command and killing some processes that were running but shouldn’t have been. Your mileage may vary."

What are these commends you speak of?

The "com.apple.extensionKit.errorDomain error 15" prevented me to update MacOs from 13.3.1 to 13.4 on a M1 Macbook Pro.

My remedy:

I just searched for "extensionkit" using the activity monitor and instantly killed the applications which utilized the "extensionkitservice". To be sure, I also killed any orphaned "extensionkitservice" process too. The MacOS could be updated successfully afterwards.
