@marioguzman I thought I’d ask, do you happen to know how Apple implemented the world map view used in the Date & Time settings (specifically the time zone selector)? It doesn’t seem to be a standard AppKit control and I’m curious whether it’s a private framework, a custom NSView, or something else entirely.

Any insight would be much appreciated!

Got a user request for templates in Octavo (my Mac app for PDF imposition).

Do you guys think I should build on top of the "Stationary Pad" finder flag? Do any of you actually use that? Advantages of using it, it'd handle the open-as-new-document flow for me. But the disadvantage is, I couldn't set a separate icon or extension for the template files.

As many commentators have said, with the MacBook Neo selling like crazy, now is a great time to be a Mac app developer.

Does anyone know how to navigate between preference panes of apps on macOS using the keyboard?

I tried to highlight the toolbar buttons and moving the focus works, but selecting the focused pane by, e.g., pressing Space only gives the error sound.

Seems like an obvious thing to do...

Ish. The Swift Playground app on macOS is Catalyst. Guess I can't use it as a workaround for Xcode 26.3 Playgrounds crashing on Sequoia.
