MacOS install misery

[Israel Hands]

My PC has died and I thought it was a good time to install Leo on the 2014 MacMini that's been lying around. It's running Mojave.

I've slogged through the misery of installing Xcode for an older OS and the CLI utils and Homebrew and Python and Git and QT and then grabbed Leo from Git and then run 

python3 launchLeo.py from the leo directory.

Leo starts and fails with a message

Cannot import QT  -

I try  brew info qt

And get....

qt: stable 6.2.2, HEAD

Any thoughts or wisdom. As you might have guessed I do not really know my way round bash or homebrew or git or any of it really!
