Orange add-ons for Mac Os install OK but are not available in the canvas - any clue why?

Question

I can't get the add-ons to appear on MacOS although the install seems to proceed OK e.g. for Text or Education Modules.

I've added these lines to my profile but still no luck.

export PATH=/Applications/Orange3.app/Contents/MacOS:/Users/jonnylawrence/Library/Python/3.6/lib/python/site-packages:$PATH export PYTHONPATH=/Users/jonnylawrence/Library/Python/3.6/lib/python/site-packages

Any help appreciated?

Thanks
