Operating MB Pro Mojave. 16 gig. 500 SSD
How is it even possible that I am having latency problems in Audacity with this machine?
I have no such problems in LOGIC, Cubase, Performer< Garage Band.
I have watched the latency fix movie but there must be a simple setting for this!

Which “latency” are you talking about. There are two: 1) the delay between sound going into Audacity and coming out again when you use Software Playthrough; 2) the delay between a sound going into Audacity and that sound being laid down in a track (during overdubbing).

There is nothing you can do about the first.

For the second, have a look at this manual page.
