[Elecraft] Clock Accuracy

[Randy Heise]

As a new FT-8 user on my K2, I find this thread fascinating. But all these software solutions appear to be for PC’s. Is there something equivalent for Macs?

I couldn't care less if it was 2 minutes off for logging (even for contesting), but for FT8 it should be, as you say, 0.5 seconds or better for best results.  Meinberg (which is free) puts me within one or two tenths of a second of everyone else.
