How to create custom toolbars on mac that can be shared with other users easily?

Hi @rrp -

No, not exactly. The limitation is only on these tabs:

You cannot customize these :point_up_2: in Rhino 5, 6, or 7. We hope to eliminate this limitation in Rhino 8 (@JohnM is actively working on it now).

That said, today, in Rhino 5, 6 and 7, you can add your own custom “tool palettes” (the Mac word for Toolbars). You can transfer these with ExportPreferences and ImportPreferences.
