It's too bad people keep trying to use the M1 for power user tasks. The hardware shortcuts and proprietary implementations make using the machine in anything but factory use cases tedious if not infeasible. Being able to change the backlight intensity shouldn't have to be a major accomplishment with unfixable sporadic hardware bugs.
It’s actually been a great experience for the most part. I certainly wouldn’t call it “tedious if not infeasible”.
It’s a new platform so I don’t expect every single feature of every piece of software to work on day 1, but I haven’t encountered anything show-stopping.
Not being able to adjust monitor brightness using a 3rd party tool for a few months until the developer adds the new hardware isn’t really the end of the world.
