"Legacy Developer:Perceptiveautomation" message in Big Sur

I just upgraded to Big Sur and am getting the following message in the Security & Privacy preference pane: "System software from developer 'Legacy Developer:Perceptiveautomation' was blocked from loading." How do I get rid of this message? Is there some fossil file on my system from some previous version of Indigo?

It might be because you still have the kernel extension installed that enabled 2414U and CM15 support. Try removing this file:

Code: Select all

/System/Library/Extensions/IndigoOverrides.kext

Might have to reboot for that message to go away. In either case, let us know what you find.

No such file in /System/Library/Extensions, but I do find it in /Library/Extensions and /Library/StagedExtensions/Library/Extensions. Should I delete these?

Sure, delete them all and let us know the results.

I can't seem to delete the one in /Library/StagedExtensions/Library/Extensions, but I got rid of the other, and the message didn’t reappear after rebooting.

Good news, thanks.
