opening filesystem dialogs very slow on MacOS

For all 3.x versions to date (and in different user profiles) any action in QGIS that opens a system dialog (e.g. saving or opening any file) results in a long wait for the dialog to completely render and populate and for the cursor to become responsive again.
Nothing else on the system is slow and it doesn't happen with 2.18 so it's definitely a 3.x phenomenon.
