Four days from now, every Apple Vision Pro owner will receive the most consequential software update the headset has ever seen. Apple seeded the Release Candidate for visionOS 27 — build 24M362, the final pre-release build before public distribution — on Tuesday, September 9, the same day the company's "Surprise and Shine" hardware event unveiled the iPhone 18 Pro, iPhone Duo, and AirPods 5 at Apple Park. MacRumors, iClarified, and AppleInsider confirmed the visionOS 27 RC with build 24M362 seeded September 9. The RC's arrival closes out a development cycle that ran through eight developer betas from June through August 31; barring a last-minute critical bug, build 24M362 is the software that will land in Settings next Monday, September 14. AppleInsider confirms the eighth developer beta shipped August 31, with the RC following as feature-complete.

What Vision Pro owners receive on that date depends heavily on which chip sits inside their headset — and on whether they understand that visionOS 27 is not just a feature update but a quiet repositioning of what the headset is for.

What a Release Candidate Means for Your Headset

A Release Candidate is the final stage in Apple's pre-release testing pipeline. It is considered feature-complete: no new capabilities are added after this build, and only critical bug fixes are permitted before the public version ships. The visionOS 27 RC follows the same logic that governed the iOS 26.6 RC in July — the build number you see in Settings on September 14 will almost certainly match 24M362. 9to5Mac confirms RCs as final shipping software. If you are enrolled in the Apple Developer Program or the public beta program, you can install RC1 right now by opening Settings → General → Software Update → Beta Updates on your headset.

Siri AI Comes to Vision Pro — With a Spatial Twist

The headline addition in visionOS 27 is Siri AI, Apple's rebuilt conversational assistant that can hold multi-turn exchanges and draw on both general world knowledge and personal user data like messages, photos, and calendar events. On Vision Pro, Siri AI receives capabilities no other Apple device can replicate: because the headset's cameras and eye-tracking feed the assistant in real time, Siri can answer questions about whatever the wearer is actually looking at — identifying physical objects, reading on-screen text, interpreting the scene around them — through a feature called Visual Intelligence. MacRumors documents the Visual Intelligence integration in full.

The interface for accessing Siri has also been redesigned from the ground up. A three-dimensional orb — persistent, placeable anywhere in the wearer's virtual space — replaces the traditional Siri invocation interface. Eye contact with the orb is enough to begin a conversation; no "Hey Siri" required. A dedicated Siri app stores previous conversations for review and continuation across devices, synced through iCloud. Road to VR confirmed the orb's placeable persistent design and the iCloud conversation sync. A conversation that started on a Mac can pick up on Vision Pro.

Siri AI ships in beta on September 14, available in English. Apple has confirmed that French, Japanese, Korean, Portuguese, and Spanish support will follow in October; no timeline has been given for when the feature exits beta. Engadget confirmed the five-language October rollout from Apple's September 9 announcement. Vision Pro will be one of only two Apple platforms to receive Siri AI in the European Union at launch — an unusual outcome for a company whose EU iPhone and iPad Siri AI features remain subject to regulatory delays.

What M2 owners get: The full Siri AI experience powered by the standard AFM 3 Core model — Visual Intelligence, the orb interface, the conversation app, and real-time scene awareness.

What M2 owners do not get: Siri voice customization. The ability to tune Siri's tone, expressivity, and speaking pace is exclusive to the M5 Vision Pro, for architectural reasons covered in depth in our August coverage. TechTimes article 324008 documents the M5-only voice customization architecture in full.

How Siri Routes Queries on Your Headset

Understanding what Siri AI can do on Vision Pro requires understanding where the actual thinking happens. Apple's system uses a three-tier routing architecture. TechTimes article 317985 documents the Siri three-tier routing architecture from its WWDC 2026 origin.

Simple queries stay on the device, handled by Apple's own models — AFM 3 Core on M2 headsets, or the larger AFM 3 Core Advanced on M5 units. Moderately complex requests escalate to Apple's Private Cloud Compute servers. The heaviest reasoning tasks route to a custom 1.2-trillion-parameter Gemini model running on Nvidia Blackwell B200 GPUs in Google Cloud; Apple anonymizes and tokenizes queries before they reach Google's infrastructure, and its contract with Google bars training on user data.

The practical difference between M2 and M5 owners lies in where the Tier 1/Tier 2 boundary falls. Because the M5 runs the 20-billion-parameter AFM 3 Core Advanced model — which loads only the relevant subset of its weights from NAND flash per query rather than holding everything in RAM — it handles a larger category of requests entirely on-device. M2 owners will see more of their complex Siri interactions routed to Private Cloud Compute or beyond.

Spatial Interface Changes: What visionOS 27 Feels Like

Beyond Siri, visionOS 27 delivers a series of changes to the spatial computing environment itself that add up to a meaningfully different day-to-day experience:

Curved app windows. Application windows now carry a subtle inward curvature that follows the geometry of the wearer's field of view. Safari, Apple TV, Freeform, and other apps render with this wrap applied, designed to make extended work sessions feel more spatially natural and reduce the sense of flat panels floating in space.

Extra-small widgets. A new widget tier — smaller than any widget size previously available in visionOS — lets owners pin compact at-a-glance information anywhere in their space. An example Apple has demonstrated: a Mac Virtual Display widget that lets you connect to a Mac with a single tap from wherever you've anchored it in the room.

Eye-aware notifications. Notifications automatically expand when the wearer looks at them. The change removes a layer of deliberate interaction — no hand gesture required to read an alert — and aligns with Vision Pro's core design philosophy that eye contact is the most natural attention signal in a headset.

Redesigned Control Center. The Control Center has been reorganized into three distinct zones — notifications and playback, main system controls, and environments — making system navigation faster and requiring less hunting through panels.

Spatial panoramas. Owners can now convert their own panoramic photos into fully immersive environments and set them as their home backdrop. The implementation builds on the Gaussian splatting depth technique Apple introduced in visionOS 26 for regular photos; panoramas now extend that treatment into fully surround experiences.

Thórsmörk environment. A new built-in immersive environment, set in Iceland's Þórsmörk (Thor's Wood) glacier valley in the southern Highlands, brings dramatic mountain and valley scenery with the northern lights visible overhead.

Wi-Fi connection speed. Apple says the headset now connects to Wi-Fi up to three times faster after booting, based on Apple's own testing comparing an M2 Vision Pro running visionOS 26.6 against a pre-release build of visionOS 27. Apple's visionOS 27 page and third-party testing confirm the Wi-Fi claim. This is a connection initiation improvement — how quickly the headset becomes network-ready after you put it on — rather than a raw throughput increase.

Vision Pro as Enterprise Peripheral: What Foveated Streaming Changes

The most strategically significant addition in visionOS 27 may be one that generates the least consumer press attention: the Spatial Preview and Foveated Streaming frameworks, which together give Apple Vision Pro a third path to becoming useful in enterprise workflows without requiring developers to build native spatial apps from scratch.

The Spatial Preview framework connects a Mac application directly to Quick Look on visionOS, allowing developers to push spatial photos, 3D content, live USD scenes, PDFs, and Apple Immersive Video to Vision Pro without writing a separate headset app. Apple's developer documentation confirms Spatial Preview's full feature set. A designer working in Cinema 4D or SketchUp can review their 3D model in full spatial scale on the headset while the Mac app continues running — annotations, adjustments, and SharePlay collaboration included.

The Foveated Streaming framework, introduced earlier in visionOS 26.4 and now expanded in visionOS 27, goes further: it creates a session-based API that lets Vision Pro stream high-quality visual content from a PC, workstation, or cloud server, with rendering bandwidth concentrated precisely where the wearer is looking at any given moment. UploadVR's reporting on Autodesk VRED automotive streaming deployments documents real-world production use. The framework integrates with the NVIDIA CloudXR SDK, meaning existing OpenXR applications — including PC games and enterprise simulation software — can become streaming endpoints for Vision Pro without a complete rebuild.

This architecture is already deployed in production. Autodesk VRED added immersive streaming support for Vision Pro, and automakers including Kia, BMW, Volvo, and Rivian are using the feature for design review. Flight simulation software X-Plane and racing simulator iRacing have announced PC-streaming visionOS clients. The pattern is consistent: Vision Pro is finding its commercial footing not primarily as a consumer device but as a spatial display layer for existing professional software — a peripheral for the Mac and PC ecosystem rather than a standalone computing platform.

One technical note worth flagging for enterprise buyers: Foveated Streaming sends gaze location data to the streaming endpoint host (a PC, workstation, or cloud server) in real time, since gaze position is what determines where the rendering bandwidth goes. Organizations evaluating the framework for sensitive environments should assess whether gaze-tracking data flowing to their endpoint hosts is consistent with their data handling requirements.

Competitive Context: What visionOS 27 Is Responding To

visionOS 27 arrives as the broader mixed reality market remains difficult. Samsung's Galaxy XR headset, released in October 2025 at $1,799 — roughly half the Vision Pro's $3,499 price — runs Android XR, developed with Google and Qualcomm, and carries a Snapdragon XR2+ Gen 2 chipset. 9to5Google confirms Galaxy XR's $1,799 price and October 2025 release. The Galaxy XR has expanded into European and Canadian markets in 2026.

Apple's software response leans into what the Vision Pro's silicon advantage enables. The M5 Vision Pro's AFM 3 Core Advanced model handles a category of AI inference that the Snapdragon XR2+ Gen 2 cannot replicate in the same on-device architecture. The EU availability of Siri AI at Vision Pro launch — while Samsung's Galaxy XR carries Google Gemini Nano as its on-device model — is another differentiator in that specific market.

The headset itself has had a difficult 2025. IDC estimated only 45,000 units shipped in the holiday quarter, against approximately 390,000 in all of 2024. Apple cut its Vision Pro marketing spend by more than 95% in the US and UK, per Sensor Tower data cited by the Financial Times. Production partner Luxshare halted Vision Pro manufacturing lines in early 2025. Next Reality confirms the marketing and sales figures. The installed base is estimated at roughly 430,000 to 480,000 headsets total. visionOS 27's depth of capability — and particularly the enterprise frameworks that connect Vision Pro to existing professional workflows — reads as Apple's software-side answer to the question of what the headset is actually for.

How to Update on September 14

visionOS 27 will be available as a free update starting Monday, September 14. Apple typically releases software updates around 10:00 a.m. Pacific time (1:00 p.m. ET). To install:

Open Settings → General → Software Update on Apple Vision Pro. If an update is available, tap Download and Install. Ensure the headset is connected to power during the update; Apple recommends plugging in the battery pack rather than relying on the internal battery reserve during installation.

Developers and public beta testers already running the RC can install via the same path now, with Beta Updates enabled under Software Update.

Compatibility: visionOS 27 requires an M2 chip or later. Both the original Apple Vision Pro (M2, launched February 2024, $3,499) and the updated M5 model (launched October 2025, $3,499) are compatible. The only feature limited to the M5 model is Siri voice customization.

Frequently Asked Questions

What's new in visionOS 27 that M2 Vision Pro owners will actually notice?

M2 Vision Pro owners receive the full Siri AI experience — Visual Intelligence, the persistent 3D orb interface, the conversation history app, and real-time contextual awareness of whatever the wearer is looking at. They also receive all spatial interface improvements: curved app windows, extra-small widgets, eye-aware notifications, the redesigned Control Center, spatial panoramas from personal photos, and the new Thórsmörk environment. The Wi-Fi connection speed improvement applies to both models. The only feature M2 owners do not receive is Siri voice customization, which requires the M5's specific memory architecture.

What is Visual Intelligence, and how does it work on Vision Pro?

Visual Intelligence is Apple's real-time object and scene recognition feature, adapted for Vision Pro's camera and eye-tracking hardware. Because the headset's cameras see the wearer's physical environment continuously, Siri AI can respond to questions about anything in that environment — identifying a product by looking at it, reading printed text on a wall, describing what's visible in the room. On an iPhone, Visual Intelligence requires pointing the camera at a subject; on Vision Pro, the subject is whatever the wearer's gaze indicates, processed in real time without an explicit gesture.

How does Vision Pro's new enterprise streaming work, and should I care about gaze data privacy?

The Foveated Streaming framework lets Vision Pro stream content from a nearby PC, workstation, or cloud server, concentrating rendering bandwidth toward wherever the wearer is looking — which is how the framework achieves high visual quality without overloading the network connection. That process sends gaze position data to the streaming endpoint in real time. For consumer use and most enterprise deployments, this is managed within a local network where the endpoint is an employer-controlled PC. Enterprise organizations deploying Vision Pro in sensitive environments — legal, medical, government — should confirm with their IT and compliance teams whether real-time gaze tracking flowing to local servers is acceptable under their data handling policies.

When will Siri AI support languages other than English on Vision Pro?

Apple has confirmed that French, Japanese, Korean, Portuguese, and Spanish support for Siri AI on Vision Pro will arrive in October 2026, following the English-only launch on September 14. Apple has not announced a specific October date or a timeline for Siri AI to exit its beta designation.
