After reinstallation, my left shift key has the same behavior as the option key. Is there any setup to disable that? I mention that right shift key is working properly.

Thank you!

  • Test for hardware fail using another keyboard. There is no system option to make left & right shift behave differently.

    Isn't the "Start" button a Windows/PC thing? This site is for Apple products. May 15, 2022 at 1:10
