Apple's 50th anniversary celebrations will culminate in a private finale at Apple Park headquarters this week. Bloomberg's Mark Gurman revealed the upcoming event after months of global celebrations, noting a special guest performer will headline the gathering for corporate employees and select invitees.

Gurman hinted at Paul McCartney as the possible headliner, describing the legendary musician as "still going strong" and noting former CEO Steve Jobs would have been "ecstatic" about the performance. The Beatles icon would mark a meaningful choice given Apple's music industry connections and Jobs' personal admiration.

The Apple Park Visitor Center will close early at 3 p.m. Pacific Time on March 31, suggesting the event may occur that day rather than April 1 when Apple officially turns 50. The exclusive celebration reinforces Apple's tradition of keeping major milestone events private for employees rather than public spectacles.
