Doesn't work on macs with M1 chip

I have Macbook Air 2020 with M1 and this app simply doesn't work. It doesn't matter if I click on enable or use the provided keybinding.

This is a bummer. Do we know what's not working with the latest M1 Mac computers?

Hmm, looks like the non-public C++ API we are using in the app to toggle grayscale mode doesn't work on mac computers with M1 chip. I do not have a computer with M1 to test it atm.

I'm guessing this is the one? https://github.com/rkbhochalya/grayscale-mode/blob/master/GrayscaleMode/grayscale.h

Where did you find that private C++ API in the first place? Maybe we can go to the docs/code you looked at and see if they updated it to work with M1 chips.

Can you provide the info above whenever you have some time @rkbhochalya?

Looks like @brettferdosi has done an amazing job reverse engineering the proper way to toggle grayscale mode, and can be found here https://github.com/brettferdosi/grayscale/blob/master/Sources/Bridge.h

Just tested it by installing his app and it worked nicely. So we might want to port over his code into this app so that grayscale-mode can run on the Apple M1 chip family. Won't have the time to do this myself but writing it here in hope that someone else can pick it up.
