YogaSMC (1.5.1) System Preferences error when running it again (Big Sur)

[mackonsti]

Hello @zhen-zen thank you for spending time on this extension for us.

I have an IdeaPad S145-14iWL so I do believe my laptop is compatible with your kext and work.

The kext is loaded fine, using latest BigSur 11.6.5 with OpenCore 07.9.

When I launch the preference pane, it switches to YogaSMC, then I return to main System Preferences icons via the main button (on top with the many black dots). When I enter again YogaSMC pane, I get this error:

If I press OK, and try again, it launches OK.

I noticed that if I start the System Preferences and run YogaSMC pane, then quit/exit System Preferences completely, and restart System Preferences and relaunch YogaSMC, I do not get this error.

I suspect that YogaSMC session is not properly killed or exited, despite clicking on the dots-button (on top) ; otherwise, the relaunch of YogaSMC (without quitting System Preferences) doesn't detect an existing/open session, perhaps, hence the error?

Have you come across this or anyone else?

Thanks for your feedback on this.

I thought this issue is gone but not sure why it happened again. There's few documents regarding prefpane development and the debugging is difficult since it couldn't be launched individually. Don't have an idea right now.

I also had the same problem, I solved by opening first YogaSMCPane from Package Contents, give the permission to execute it then add again the prefPane and it will work

Not sure the same behaviour is described here @experimentalperson

Open the pane after running System Preferences; then click on the dots icon to come back to the main System Preferences. Click again to reopen SMCPane ; it crashes... you confirm?

@mackonsti Yes exactly, inside the package contents there is another executable that has to be given permission to execute, you can open it and you will see a terminal window, and you have to unlock from security that executable too

;)

The executables are not signed and are blocked by Gatekeeper. You will need to remove the quarantine manually or control-click the icon and click open.

Hi @zhen-zen I have code-signed it locally but it still crashes when clicking on the icon again inside System Preferences window 😢

% cd ~/Library/PreferencePanes/
% sudo codesign -f -s - YogaSMCPane.prefPane
YogaSMCPane.prefPane: replacing existing signature

So @0x090909 I do not clearly understand what you did.
Do you not have the Pane crashing if you relaunch it from inside System Preferences?
I was under the impression from you @0x090909 that if you'd codesign it, it would stop crashing...
Thanks to both.
