It saddens me to announce that we are dropping official support for macOS.
Due to lack of time, hardware, dwindling interest, and Apple breaking our code for the nth+1 time, we are unable to continue supporting it.

As we do not own any Macs, we are unable to test the software, and soon with the switch to ARM, we will be unable to even run the OS to do any development whatsoever.
Somebody donating a Mac would be unlikely to fix the other issues mentioned above.

If someone wants to resume development, you are welcome to join our team. You can get in contact with us on IRC, as mentioned in the README. We'll be happy to help familiarise you with the codebase.
The macOS code will remain in master for a while, however we will not guarantee that it will compile at all.

A starting point for anyone interested in working on this would be to look at Karabiner switching to DriverKit.

Next release might also have one last macOS build, but it will not be guaranteed to work with newer versions of macOS. It will also not function on any of the ARM Macs.
