The keyboard flaked out on me once. I wanted to spend time testing the Touch ID button, so I moved an application to the Trash, which requires authentication. That worked. Then I tried to move the app back to the Applications folder, and … Touch ID just didn’t work. After 30 seconds of trying, I realized the whole keyboard just wasn’t working. I turned the keyboard off and on again, and boom, everything has been normal since — including Touch ID recognizing my finger very quickly.

Ah, ah, another moment of Apple’s Bluetooth device not working as expected. Since I got my 2017 21.5” iMac, I’ve experienced unstable Bluetooth connectivity with Apple’s mouse and keyboard. I don’t know when it started, if it’s related to a certain release of macOS, but it is happening all the time. The worst part is the mouse being jerky while moving on the screen. Bluetooth’s instabilities also impact my AirPods usage with the Mac. My AirPods simply drops from receiving the Mac audio while in Zoom meetings. It is infuriating. Eventually, I need to reboot the Mac to reset the Bluetooth stack.

When I got the M1 Mac mini, I thought Bluetooth connectivity issues would be a thing of the past. I couldn’t be more wrong. It was worst. The mouse and the keyboard are both having instabilities. They need to be turned off and on to temporarily fix the problem, but eventually the Mac needs a full reboot. Again, this is exasperating. It is a well documented issue which macOS 11.1 and 11.2 tried to fix but the problems still happen, albeit a bit less often.

There is something wrong with Apple’s Bluetooth implementation in general. Is it the driver, the firmware, the chip, a combination of these that is at fault? I don’t know but the fact that this shiny new iMac with the wireless keyboard with TouchID stops working like Gruber experienced is not a good sign.
