If you have serial appintments in your calendar that were created with old GroupWise clients (BEFORE 14.0.2) OR individual appointments from the series have been changed, then not all appointments may appear on your Mac calendar.
Multiple address books do not appear on the Mac - this is a limitation of MacOS - on an iPhone connected via CardDAV all address books appear.
GroupWise distribution lists do not appear in the address book - this is a MacOS limitation - Apple Contacts does not support groups yet.
Shared calendars (from other people to you) do not support push updates (i.e. you may have to wait up to an hour for an update (or press Command-R).
Substitution access is not available - and probably never will be, as this is not part of the CalDAV/CardDAV concept.
Support for MacOS-X "tasks" is not (yet) available.
