Alongside providing the first release candidate version of iOS 16 to developers, Apple today has also seeded new beta versions of iOS 15.7 for the iOS 15 operating system and macOS Monterey 12.6 for the Monterey operating system.
Both updates are release candidate versions, which means they could see a launch in the near future. The iOS 15.7 update has a version number of 19H12, while macOS Monterey 12.6 has a version number of 21G115.
Registered developers can download necessary profiles to install the updates from the Apple Developer Center, and can download the updates from there.
According to the iOS 15.7 release notes, the update provides security updates rather than new features.
Apple has unveiled a whopping nine new products so far this March, including an iPhone 17e, iPad Air models with the M4 chip, MacBook Air models with the M5 chip, MacBook Pro models with M5 Pro and M5 Max chips, the all-new MacBook Neo, an updated Studio Display, a higher-end Studio Display XDR, AirPods Max 2, and now the Nike Powerbeats Pro 2.

iOS 26.4 isn't the major update with new Siri features that we hoped for, but there are some useful quality of life improvements, and a little bit of fun with an AI playlist generator and new emoji characters.

While the iPhone 18 Pro and iPhone 18 Pro Max are not expected to launch for another six months or so, there are already plenty of rumors about the devices.
It was initially reported that the iPhone 18 Pro models would have fully under-screen Face ID, with only a front camera visible in the top-left corner of the screen. However, the latest rumors indicate that only one Face ID component...
Is this for all iOS 15 devices or just the ones not getting iOS 16?
All.
I suspect this will be like iOS 14.8, and you'll be able to choose if you want to install 16.0 or 15.7.
The firmware codenames or "build trains" are: ... 14.5: AzulE 14.6: AzulF 14.7: AzulG 14.8: AzulSecuritySky ... 15.5: SkyF 15.6: SkyG 15.7: SkySecuritySydney 16.0: Sydney
So it seems like a similar pattern, 14.8 was "iOS 14 with security updates backported from iOS 15", and 15.7 is "iOS 15 with security updates backported from iOS 16".
If anyone's wondering how to see the macOS 12.6 RC, install the Profile for Ventura, but then select Other Updates and it'll come up there. I was also offered a new Safari Seed, not the Tech Preview.
Once completed, remove the profile by reverting back to Default settings under Software updates. If there's a new build when it's officially released, you'd still get that, otherwise you'd be on it anyway...
It'll be interesting to see if iOS 15.7 will be available in .ipsw form to allow downgrading from iOS 16 or if it'll only be available as an on-device alternate software update.
15.7 release candidate is already available in ipsw form.
It remains to be seen if the final build will be the same, if there will be an ipsw of the final build if it's not the same as the RC, and if there will be an ipsw for 15.7.1 and later ones...
