System Settings breaks in macOS Sonoma

[popaprozac]

Issue
System Settings fails to open after setting a default app

Steps to reproduce

• msda set com.google.chrome -p http -p https -u public.url all -u public.html viewer -u public.xhtml all -fut or any set command.
• Attempt to open System Settings.

Symptoms
After setting any app as a default app, System Settings fails to load properly. The app launches but does not display any windows and this is the View menu:

Workaround
I have been able to reset the LaunchServices and open System Settings by running the following:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -all local,system,user

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -seed

The good news is the change is applied successfully so after resetting all LaunchServices System Settings open and the default app is set correctly.

Looks like removing the sudo command from the rebuild fixes the issue.
Will submit a PR asap.

@popaprozac 2 questions:

• Are you running the command from your OP as root?
• Is there a logged in user when you run that command?
• How are you running this command? (e.g. via MDM, manually, etc.)

The script tries to reset the LS database as the currently signed in user or root, depending on the context. My concern is that removing sudo altogether could cause issues in certain contexts (e.g. Setup Assistant).

Thanks for the follow up!
The package is deployed via MDM but the script is run separately via a policy. I found that removing sudo from msda when running the policy via MDM or locally (both situations with a logged in user) it runs as expected. When running locally I use sudo msda but the script run via policy omits the sudo.

Same issue here - any ideas how to fix it? - Running the script through JAMF

I suffer from the same issue.

• command is executed as root through MDM (Mosyle)
• local user with standard privileges was logged in at the time

I could fix it as mentioned by the OP by running

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -all local,system,user
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -seed

as local user (NOT root). The weird thing is that I did run it as

sudo -u localuser cmd

which is identical to what your script does... however, it seems to fail in your case for some obscure reason. So my solution is to simply run above commands at the end of my script...

I'm working on v2 of this app under the jxa-v2 branch. It should resolve this issue. I don't have an ETA at this time, but I'll follow up once it's released.

Great thank you!
