The macOS Tahoe 26.7 release candidate seeded today contains references to numerous unreleased Apple products, spanning home devices, AirPods and Beats, several iPhone models, iPads, Macs, a headset, and an Apple TV remote.
macOS Tahoe 26.7: Home accessories
The build includes multiple home device codenames. J490 and J491 appear with Siri setup references; J490 is believed to be the home hub version with a base and J491 the wall-mounted variant. A product codenamed B525 is mentioned in connection with an “Argentium” installation and likely corresponds to the HomePod mini, whose current codename is B520. There is also a reference to “J229Architecture,” a previously seen codename for an unreleased accessory with multiple sensors capable of detecting alarm sounds and capturing images, which could be a security camera or an accessory for the home hub.
Other home-related entries include a “Pebble” reference tied to the homeOS operating system for the home hub, model identifiers HomeAccessory17,2 and HomeAccessory17,3 without clear public mappings, and color options listed as Rose Pink, Silver, Space Gray, and Starlight for an unnamed home accessory. The code also contains an “audio_accessory_visual_reasoning” string that may relate to the home hub’s capabilities.
Headphones
Code references several headphone projects. B790 appears as a codename for AirPods with a camera; the code specifically logs “B790 start image stream failed for left bud.” These B790 AirPods are described in the code as distinct from another camera-equipped AirPods project codenamed B798. Entries B518 and B522 could reference upcoming Beats models. There is a mention of AirPodsPro1,4, which could denote fourth-generation AirPods Pro, plus a reference to AirPod3,5.
iPhone
Multiple iPhone codenames appear in the macOS build. V62 is associated with an iPhone Air 2, not expected until spring 2027. V63 and V64 correspond to the iPhone 18 Pro and iPhone 18 Pro Max, respectively, which are expected in September. V67 maps to the iPhone 18, expected in spring 2027, while V68 is listed as the iPhone Ultra, a foldable model expected in September.
Mac
The code references Mac hardware in development. J804 is identified as the entry-level 14-inch MacBook Pro slated for an M6 update before the end of the year; the current M5 14-inch MacBook Pro is J704. J833 and J834 are listed as new iMac model codenames. Additional MacBook Pro identifiers—K114c, K114s, K116c, and K116s—likely reference higher-end MacBook Pro models, possibly OLED variants.
iPad
Next-generation iPad mini codenames J510 and J511 appear, reportedly tied to a model expected to adopt an OLED display and A19 Pro chip.
Headset
N109 is present in the code. This identifier has previously been associated with a second-generation Vision Pro or a lower-cost Vision Pro variant; reports indicate a more affordable Vision Pro version was reportedly canceled last year.
Apple TV Remote
The build mentions ATVRemote1,5, suggesting a new Apple TV remote. Previous rumors have indicated the possibility of an updated remote accompanying a future Apple TV.
Apple Intelligence in China
macOS Tahoe 26.7 contains references to Writing Tools coming to China along with messages about temporary restrictions and content safety. Example strings in the code include: “Content safety update required. iPhone will be able to use Writing Tools once the automatic update completes.”, “Unable to edit this text. %1$@ may be able to help with this type of content. This text will need to be sent to %2$@.”, and “Writing Tools are temporarily restricted due to triggering safety alerts multiple times.” These entries indicate limits on Apple Intelligence editing for certain content in China until a safety update or review occurs.
Unknown model numbers
The release candidate lists multiple model numbers that do not match existing Apple products and lack clear ties to known releases: A3436, A3437, A3438, A3439, A3440, A3441, A3456, A3457, A3465, A3529, A3530, A3531, A3532, A3533, A3543, A3577, and Device1,8234; Device1,8236; Device1,8238; Device1,8240; Device1,8241; Device1,8242; Device1,8246; Device1,8247; Device1,8248.
The first devices referenced on this list are likely to appear in September, when Apple is expected to introduce the iPhone 18 Pro, iPhone 18 Pro Max, and iPhone Ultra. Timing for new home products, Macs, and iPad mini models is not specified; Apple often stages two fall events, so a second event in October or November could cover MacBook Pro, iMac, iPad mini, and home accessories.
