Two code references discovered in today’s macOS 26.1 Tahoe beta 3 release point to a camera being part of the next-gen Pro Display XDR: “Pro Display XDR Camera” = “Pro Display XDR Camera” and “Pro Display XDR Desk View Camera” = “Pro Display XDR Desk View Camera.”
Desk View Camera implies that the built-in camera will support Center Stage and ultra-wide perspectives.
