This is a follow-up to the Mac part of my post titled "X-13ARIMA
updates for Windows and Mac". The new Mac package is now called
x13as-mac-arm64.tar.gz and it works like the Intel version, in that it
can be installed from the gretl console via the command
pkg install x13as-mac-arm64.tar.gz
I'm still not sure if it will work on Big Sur or Monterey (my only
testing was on Ventura) so I'd be interested to hear any comments on
that point.
