Apple is ramping up production of the Vision Pro mixed-reality headset, setting the stage for a launch by February, Bloomberg News reported on Wednesday, citing people with knowledge of the matter.

Production of the new headset is running at full speed at facilities in China and has been for several weeks, according to the report.

The company sent an email to software developers on Wednesday encouraging them to “get ready” for the Vision Pro by testing their apps with the latest tools and sending their software to Apple for feedback, according to the report.
