keyboard only working in Recovery Mode
My Macbook Pro Early 2015 keyboard + trackpad has stopped working. I was able to re-install macos (big Sur), the keyboard worked again for a few days then the same problem occured. I then factory reset the mac to El capitan. Keyboard worked fine. Updated again to Monterey, the keyboard worked again for a few days then now it is not working again. The command + R command works. Do I have to remain on my old OS since it looks like it only happens since Big Sur.
Keyoard and trackpad works fine with El Capitan
With a factory version of monterey the keyboard/trackpad stops working, in recovery mode all works fine.
Looks like it's not hardware so I most not be the only one with this problem?
Thank you for your advice.
