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

I have also the same problem someone please help me .

I'm having this too com.apple.extensionKit.errorDomain error 15.

I have wiped my mac and set up as new and no luck!!!!

Same here when I try to view System Settings/Network/Wifi. Basically can't change DNS or anything. WTF Apple. You've effectively bricked my machine with this "upgrade".

I received this same error when trying to enter wifi menu options under network settings.

Ugh. This is my EXACT issue. Did any of these work for you?

Having error on intel mac, 13.3.1: Settings Error The operation couldn't be completed (com.apple.extensionKit.errorDomain 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.

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

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.

SAME here. Upgraded O/S and kaboom, bad news after that.

I ve done this and it instantly fixed my iMac 2017 booting issue. I’m appalled that a Mac update could let such an annoying issue occur. But thank you for being more helpful than Apple employees.

Success! go to network >> lower right corner of page to "...". then "add a new bridge."

Fixed, Whew!

Fine ! Just do the same with "Wi-Fi" and it's ok

thanks a lot

I get this error when in "System Settings" > "Wallpaper" when clicking the button for selecting an album. It happens repeatedly and won't let me add wallpaper from Photos.
