how can i register event march 4 2026

If you mean the Apple Event scheduled for March 4th, Apple has invited select press to attend. It is not open to the general public. From what I can see, it doesn't appear Apple has suggested they'll be streaming the event.

If you're an invited guest, you would know how to attend. Since you're asking, it appears you likely didn't receive an invitation.

We may have to rely on our favorite YouTube Apple pundit for live streaming of the event.
