Project templates and wizards do not appear on macOS

[ddobrev]

I use QtCreator 4.3.1 with Qt 5.9.1 on macOS Sierra 10.12.6. I have followed the instructions at https://github.com/qtquickvcp/MachinekitSDK#install-with-qtcreator. I can see the files are copied:

/<user_path>/Qt/5.9.1/clang_64/bin/qmake -install qinstall /<user_path>/Projects/MachinekitSDK/qtcreator/wizards/machinekitapplication /<user_path>/Qt/Tools/QtCreator/share/qtcreator/templates/wizards/machinekitapplication
/<user_path>/Qt/5.9.1/clang_64/bin/qmake -install qinstall /<user_path>/Projects/MachinekitSDK/qtcreator/wizards/qtquickvcpproject /<user_path>/Qt/Tools/QtCreator/share/qtcreator/templates/wizards/qtquickvcpproject
/<user_path>/Qt/5.9.1/clang_64/bin/qmake -install qinstall /<user_path>/Projects/MachinekitSDK/qtcreator/wizards/halfile /<user_path>/Qt/Tools/QtCreator/share/qtcreator/templates/wizards/halfile
/<user_path>/Qt/5.9.1/clang_64/bin/qmake -install qinstall /<user_path>/Projects/MachinekitSDK/qtcreator/wizards/bbiofile /<user_path>/Qt/Tools/QtCreator/share/qtcreator/templates/wizards/bbiofile

but no project templates or wizards appear in the IDE after I restart it or even the entire computer.
