ExtensionKit Error 15

I am encountering the same error as you. It occurs when I follow these steps:

1. Go to System Settings > Internet Accounts.
2. Select iCloud from the list of accounts.
3. Navigate to the Apps Using iCloud and then click Show All.
4. Click on the back button.

Instead of returning to the list of Internet Accounts, I see an error message. However, this error does not happen if I skip any one step from the list above.

I am using an M1 Mac Mini with macOS 13.3.1. Curious what's causing this, and hoping that Apple releases a fix soon.

This happens to me when I go to Settings/Privacy & Security there is a sentence below the radial buttons to allow applications from the app store or app store & identified devs, it reads "Some system software requires your attention before it can be used." there's a button below that "Details..."

When I click that an error pops up Settings Error: The operation couldn’t be completed. (com.apple.extensionKit.errorDomain error 15.)

Sucks, I just spent $20 on an app from the App Store that I can't use until this is fixed.

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.

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.

Curious to know which ones you came across. I also started to thing same thing and I am on an M1 MBP 13"

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 gave up and wiped my machine and did a clean install/update. Everything seems to be working now.

Extreme solution, but seems to be a solution.

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.

What are these commends you speak of?

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?
