My Macbook Pro M1 Max runs everything blazingly fast, even old executables
compiled for Intel CPUs. I find that surprising, given that the M1 CPU has
to emulate the Intel instructions. But it does and it's great!

The WSJT-X web site doesn't appear to offer a different version for M1, so
I think I'm running the same WSJT-X executable that I was using on my old
Intel-based Macbook. It runs much *faster* than it did on the old machine.
In fact, WSJT-X performance was one of two reasons I upgraded to a newer
Macbook: On the old machine, I was having sporadic problems with transmit
audio dropouts. Apparently it was overloaded. No problem on the new
machine. (The other application was Lightroom, a photo-finishing and
archiving program. *I'm not sure whether it's a separate compile for M1*
but the picture-adjusting sliders now work in real time, much faster than
on the old computer. The System Info panel Graphics section does say
"Metal: M1" so the code appears to be at least aware of the CPU type.)

I'm also running Parallels Desktop on this new Macbook Pro. Several
Windows-only programs that I use run faster on Windows 11 ARM Preview under
Parallels than they do on a native Windows 10 Dell XPS-13 laptop (about 5
years old). These are all Intel compiled executables. If Parallels comes up
with a fix for their generic serial port driver, or if N1MM makes serial
ports non-essential for keyer and SO2R switching, then I'll be able to
retire the Dell (as I did the old Macbook) and finally enjoy a
single-machine life. My breath is bated!
