libpython3.x

[Jeff]

Read the suggestion and I used pyenv to Install Python 3.8.1
Checked what was installed
Jeff@Jeffs-iMac ~ % pyenv version
3.7.6 (set by /Users/Jeff/.pyenv/version)
Installed 3.8.1
Jeff@Jeffs-iMac ~ % pyenv install 3.8.1
python-build: use [email protected] from homebrew
python-build: use readline from homebrew
Downloading Python-3.8.1.tar.xz...
-> https://www.python.org/ftp/python/3.8.1/...8.1.tar.xz
Installing Python-3.8.1...
python-build: use readline from homebrew
python-build: use zlib from xcode sdk
Installed Python-3.8.1 to /Users/Jeff/.pyenv/versions/3.8.1

Checked what it was using
Jeff@Jeffs-iMac ~ % python -V
Python 3.7.6
Changed it to 3.8.1
Jeff@Jeffs-iMac ~ % pyenv global 3.8.1
Checked what it was using
Jeff@Jeffs-iMac ~ % python -V
Python 3.8.1

So Tried again
Home Automation Domoticz
Ran Domoticz
Result
Status: PluginSystem: Failed dynamic library load, install the latest libpython3.x library that is available for your platform.
Status: EventSystem - Python: Failed dynamic library load, install the latest libpython3.x library that is available for your platform.
so again Python not running

using find I have:
