BrightIntosh VS Unshaky

That said, displays can technically go beyond the maximum (after all, it already does for HDR contents). It's "possible" in the sense people can do it. https://github.com/niklasr22/BrightIntosh

If the sticky keys come back, you can use software like this to mitigate it reasonably well.

I use Unshaky as it fixes the issue entirely on my 2016 13”. Maybe that could be mentioned to a possible buyer?

I have an M1 now and it is glorious but back when I had the MBA with the butterfly keys, someone pointed me to https://github.com/aahung/Unshaky and it helped eliminate 99% of the double-typing or ghost keys. You will have to tweak the ms until you find the right number that fits your typing speed but once you get it all setup, the butterfly keyboard will become much more tolerable.

Or.. you could just swap it for an M1. :)

In case you didn't know there's an app which did resolve most of the problems for me, when I had the MacBook with the butterfly keys: https://github.com/aahung/Unshaky

I believe there’s software for detecting and removing double typed letters. It was developed for people suffering the same issue on butterfly keys. Google for it. Here’s one app example.

I found this: https://unshaky.nestederror.com

Unshaky is exactly what you're looking for

If your issue's double key presses, you can install Unshaky, then open the app's settings and set the delay to 40 or 50 ms (depending on how fast you type).

I think i found something for it... maybe it's : https://github.com/aahung/Unshaky/releases
