Mac OS X disk image with [relocatable application
bundle](https://en.wikipedia.org/wiki/Bundle_%28macOS%29#macOS_application_bundles).
Needs [[xquartz][<xquartz:>]] (X11) installed for running the
[[development tools][</IDE.html>]]. The bundle also provides the
commandline tools in the =Contents/MacOS= directory. Users of older
MacOS versions are adviced to use Macports, Homebrew or install from
source.  This bundle contains universal (fat) binaries that run natively
on Intel (x86_64) and Apple Silicon (M1-3, arm64).
