> the nail on the coffin for kernel extensions The OpenZFS implementation on macOS also requires kernel extensions, and I don't suppose it can easily be ported to FUSE or that that would have desirable performance characteristics. Special kernel extensions are also required to get some basic functionality working on macOS these days, like disabling pointer acceleration.
> disabling pointer acceleration Could you point me to the kext that does that? I’ve been trying to find a way to disable it for ages.
This is what everyone uses. Mouse acceleration disable is a dealbreaker for me- I won’t update unless something supports it.
