Apple's VR/AR headset is likely to debut at the 2023 WWDC and may feature an entirely new operating system called xrOS.

Now that new operating system, and its rumored name, seems almost certain. Combining today's series of leaks with Apple's blog postings, it appears that an entirely new operating system will be announced for developers at Apple's WWDC keynote.

First, a blog post: in an update titled "Code new worlds," Apple states that developers need to pay attention to the Apple keynote at WWDC on June 5 (1 pm EST/10 am PST/6 pm UK ET/3 am CST) The company said that developers need to pay attention to the Apple keynote at WWDC. Expectedly, the reference to a "new world" is for Apple's new operating system for mixed reality apps. These apps will form the core of the new Apple headset, along with the large number of iPadOS apps already rumored to run on the new headset.

However, other information has come to light that seems to confirm that this new OS is called xrOS. as reported by MacRumors, developer Steve Troughton-Smith tricked App Store Connect into revealing xrOS in an error message The error message revealed xrOS.

xrOS has been rumored as the name of Apple's mixed reality OS for some time, along with realityOS and xrProOS. Earlier reports suggested that RealityOS was built on a platform similar to iOS, while xrOS was said to resemble macOS.

However, this xrOS example is the first time we have seen an official one from Apple in the wild. Therefore, it seems that xrOS should be a reality, even if other VR/AR-focused platforms eventually become a reality.

But it's not just the new OS that leaked today, as a tweet from Display Supply Chain Consultants insider Ross Young, h/t AppleInsider, revealed the Apple VR/AR headset's revealed possible specs for the display. Initially, the tweet appeared to be a subscriber-only tweet, but Young has since tweeted publicly about the matter.

According to Young's public tweet, the twin displays (one per eye) will be 1.41" (diagonal measurement) Micro OLED displays with 4K resolution for both eyes. The company also initially "targeted" a contrast ratio of 4000:1 and peak brightness of 5,000 nits or higher, but the "target" has since been removed from the tweet.

It is not clear what Young means by the term "targeting." However, given that his public tweets have removed the word, this figure may be accurate. If so, the new headset will have a truly dazzling display.

For what it's worth, peak brightness of 5,000 is well above the best cell phones and the best TVs. And since the Meta Quest 2 headset is only about 100 nits, 5,000 is incomparably brighter. The only other headset reported in that range is Meta's Starburst headset, which achieves a peak brightness of about 20,000 nits, but it is still a prototype.

Thankfully, we won't have to wait long to see what Apple's VR/AR headset will actually achieve in terms of performance. Stay tuned for WWDC coverage on the potential of Apple's groundbreaking VR headset.
