any thoughts on a timeframe as to when that might be expected to be available? (As in would it be weeks, months?)
They’ve basically been saying it will be in NoMachine 8 since last year. While they’re fixing some M1 bugs in the 7.x.x series, audio and keyboard drivers for ARM Apples will be in version 8. Searching the forums and Google for announcements of a version 8 beta has been fruitless, so don’t count on it until 2022 unless all the betas are secret and the version 8 release sneaks up on us.
