I’m not sure what gp was talking about. The TouchID sensor also doubles as a physical power button(or a sleep if pressed briefly). It is a physical button too, not like the iPhone ⅞ buttons.
Yeah... I'm aware of that which is what made OP confusing. They're either talking about the Power/TouchID button (which is still physical as it has been on every other MacBook prior) or they purposely added a "Lock" button to the TouchBar and are complaining about something they added that isn't there by default.
>complaining about something they added that isn't there by default
it is part of the OS, not a third party app.
So I think that complaining that it is badly designed is fair.
I can complain about the default configuration too if you want.
It takes away the function keys I actually need and replaces them with a screen. The lack of tactile feedback is really annoying. Even after configuring the touchbar to display the function keys by default in my IDE, it still bugs me and make me 'mistype' more than ever on this strip.
It's not badly designed, though. It's a button on the TouchBar just like any other. If OP is accidentally hitting it all the time then they added it in a poor location. I have a completely customized TouchBar (thanks to Better Touch Tool) and I have never accidentally hit a button. He's blaming the hardware for user error.
