The software is one serious kludge. Yes, it supposedly can use your Mac Address book, but try finding a recently added name. There's no way to sort or search for an address in the little address book window. The addresses in that window don't seem to be sorted in any order.. perhaps date added? I typically find it just faster to copy/paste from address book into the label printer software than attempt to find an addy in the Dymo Address Book.

Also, creating labels is funky monkey. There are no 'duplicate' commands to create variations on a previously created address layout. You can probably find the file itself somewhere through the finder, then duplicate/rename/open it.

Overall, it's barely functional as an intuitive label software.
