Ned, thank you very much for your prompt reply. I checked the MD5 and it was correct for the pkg file. However, as you indicated, the problem seem to be with the macOS package installer rather than the package itself. I include the following work-around in case it may be of use to somebody else.
PROCEDURE (use at your own risk)
An alternative way to using the macOS GUI Installer, issue the following command using Terminal
-
Open Terminal
-
Change your working directory to the location of the Python pkg file
(e.g.,cd $HOME/downloads) -
Issue a command similar to
sudo installer -verbose -pkg ./python-3.11.2-macos11.pkg -target /
NOTE: replace python-3.11.2-macos11.pkg with the file you downloaded
Sample partial output from the command above:
