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.

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

Carky fixed it. Resolved this by doing the following. You'll need the root password (you can reboot normally tho):

# FYI: save all your work you're going to reboot
# cleanup/backup the iCloud/Accounts directory
md ~/Desktop/tempjunk
mv ~/Library/Application\ Support/iCloud/Accounts/* ~/Desktop/tempjunk
# reboot and then first try to open Facetime, it should save and view your internet accounts.
sudo shutdown -r now

TL;DR - 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.

So I had a similar problem and ended up making it go away... but I'm unsure precisely what I did to fix it.

My equipment load out is MacOS Version 13.4 (22F66) running on a MacBookAir10,1 (MacBook Air M1) with 16 GB. I purposely do NOT have Rosetta installed.

I'll describe the situation and what I did in case it is helpful.

In my case, the "error 15" was coming up when went Settings->Network->Wi-Fi (clicking Wi-Fi brought up the error and then no Wi-Fi settings). Interestingly, I could navigate to the Wi-Fi settings if I searched instead of clicking through Settings->Network.

I did try the following to no avail:

1. Rebooted.
2. Rebooted into safe mode and try from there.
3. While in safe mode, ran disk first aid. No help.
4. Ran Onyx and ran all of it's maintenance and clean up tasks. No help.
5. There's a reddit post also tracking this issue --- a post there says that they could suppress the error by running the Console app and pressing Start to capture log data. While that did let me see some more about the error (it shows in Console), it did not suppress the error.

The last couple of things I tried that put me back into a work state as I remember:

1. Removed the Wi-Fi service from the Network panel and then re-added it. It still failed.
2. Went into Wi-Fi settings (by searching, see above), clicked on "Details" on my current Wi-Fi connection, and slid "Limit IP address tracking" from ON to OFF.
3. After closing settings and returning, everything worked. I can now successfully click through Settings->Network->Wi-Fi with wild abandon.

So... perhaps try turning off "Limit IP address tracking" in Wi-Fi settings?

Ok so I found out my problem has something to do with external monitor and/or USB hub, after unplugging and replugging everything it works as intended.

Just as a reference I am using the following hardware:

• 2021 Macbook Pro 14" M1 Pro on MacOS 13.4.1.
• Samsung Neo G8 via USB-C to DisplayPort 1.4 (clamshell)
• UGreen USB-C Hub for Gigabit ethernet.

I did this and it worked:

There was a typo in the steps above, here's the correction:

Step 1. open a terminal, then paste in this:

mkdir ~/Desktop/backupjunk
mv ~/Library/Application\ Support/iCloud/Accounts/* ~/Desktop/backupjunk

Step 2.  save your stuff and reboot the computer

Step 3. - try opening facetime and configuring your account settings.

I think this was the first issue I encountered with my MacBook Pro M1.

My solution was pretty much as below:

Was trying to check my personal information on the Apple ID, to alter some iCloud subscription details, and would get the error 15.

As I was allowed to sign out my ID, I did that and, on signing back in (including authorizing on my iPhone)... the error resolved itself.

This worked for me today:

My IT consultant at work said it's probably a corrupt aftermarket application. I tried uninstalling one by one until I found a problem. I use OWC dock ejector for use with my OWC Mac dock. I uninstalled the dock ejector, then restarted. No more ExtensionKit Error 15.

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 had same issue and what I did was from Settings > Network > lower right page (...) > Add Services > Select Interface > Wi-Fi and rename Wi-Fi2 to Wi-Fi and click Create. Now from network view you will see 2 Wi-Fi listed, select the connected one and delete it. Now you will be able to click on Wi-Fi and Details icon without any error.

PS - For me after creating and new Wi-Fi service and deleting the old one, I was able to click on Wi-Fi and Details icon without error, try it. I believe same should apply to any other services that was giving an error after upgrading the MacOS

You might try this: Boot into the Recovery volume (boot with the Command + R keys held down  - Intel Macs) or  (How to Boot an M1 Mac into Recovery Mode), select Disk Utility and run First Aid on all available volumes. If an error is noted rerun till there is no error noted. Reboot normally and check to see if there's any change.

If that fails, reboot into Recovery volume and reinstall the system.

I have had this same error warning since at least April 20th, 2023. I have reported it, and notified Apple Support of the issue..they are definitely aware of it, but I'm guessing they are still struggling to fix this situation.

At least for me, when I access my iCloud Account through the "Internet Accounts" tab in Settings...the iCloud settings page is much slower to operate especially when you compare the speed and efficiency that same settings page receives when instead being accessed through my AppleID settings. I have noticed though, that the times I never received the error message in Internet Accounts, was because I was exceptionally slow with my keyboard clicks and trackpad scrolls...

I don't get the message when I go to my other Internet Accounts Settings...the issue has only occurred when trying to access iCloud Account Settings.

If such is a similar case to you, then I might suggest simply ignore accessing your iCloud settings through Internet Accounts, and instead just access your settings through AppleID.

If such is not a similar situation to yours, then my suggestion would be to just maneuver around with as little scrolling and clicking around as possible, and just adjust whichever settings you need to adjust painstakingly slow.

Unfortunately, I don't believe there is really an actual "fix" to this just yet. There was some speculation online that it may be an "Intel Processor Issue" but I was confirmed by Apple Support when I was on the phone with them, that this issue persists even on the apple M1 chips.

I also had "com.apple.extensionKit.errorDomain error 15"

For me, after a reboot (system got slow) my Keyboard Maestro would not work.

Requested permission Security & Privacy,

but adding it to the list did not take.

Solution appears to be:

Reboot in Recovery.

Do First Aid on MacHD (and also Recovery partition) (and also an external drive) .

Reboot normally.

All ok now.

I did this and it worked:

There was a typo in the steps above, here's the correction:

Sorry, there was a typo. the command `md` should have been `mkdir`:

mkdir ~/Desktop/backupjunk
mv ~/Library/Application\ Support/iCloud/Accounts/* ~/Desktop/backupjunk

I found a fix for this error:

go to network settings. In Other Services control click old connection (mine was AX88179a)and select Delete. I chose to option to restore when plugged back in. When I plugged my usb C to Cat5 dongle back in it worked right away.

I encountered this error while trying to assign my network address manually so that my ATEM video switcher would interface with the software via Ethernet.

hopes this helps.
