2.4.0~RC1 hangs on macOS

[Dr Eberhard Lisse]

Unload the macports python and install the XCode Command line tools
which has Python 3.9.6 in /usr/bin/python3.

If that works, perhaps even unload Macports and install Homebrew. If
you have many packages installed, make a list.

I use Homebrew including basictex (plus some addtional stuff) and copied
2.4 RC1 over the 2.3.7 provided from Homebrew. On Ventura and Sonoma (on
the latter on Intel and Silicon)

greetings, el
