Note: this is a "vintage" tip for older computers and/or systems.
If Address Book "hangs" (spinning "beach ball") when trying to create a new smart list, etc the address book database might be corrupted. Try exporting the entries, then quitting Address Book, deleting the Address Book folder in the user library, in the Application Support folder. Run Address Book again and import the entries.
If the entries won't export they are probably lost because the database will need to be deleted anyway!
I usually write a blog post about once a week. The latest post can be viewed here: We Need Trump and Musk: I wonder if Trump and Musk might like to visit here after they have finished sorting out America! (posted 2025-02-11 at 11:40:37). I do podcasts too!. You can listen to my latest podcast, here: OJB's Podcast 2025-01-30 Pragmatic Libertarianism: Freedom is important. Maybe it's all that really matters..
