On my M2 MBAir, the F5/F6 keys were changed from Keyboard Backlighting to Mic/Moon. I change the backlighting frequently so they were very useful til the M2.
I did find on Stackexchange way back a way to add a plist file to the LaunchAgents folder to remap the F5/F6 back to backlighting.
Last night I updated the M2 to macOS 26.2 and of course the plist procedure hasn’t worked as it has on previous updates (move plist file out of ~/Library/LaunchAgents, shut down, boot, add plist back into LaunchAgents, shutdown and boot). After several off/on cycles the F5/F6 keys remain tied to the, to me, useless Mic/Moon fuctions.
Searched online for about 20 min and found similar instructions but nothing new since OS 26.
Any input? have the codes used for the keys changed, so I need to change the text of the plist file or something like that? Do I need to trash the LaunchAgents folder (only one other occupant) and make a new one?
