Do I still need to download a beta profile?
No. Since iOS 16.4 (2023), Apple retired configuration-profile files. Beta access is now tied to your Apple Account: sign in at beta.apple.com (public beta) or developer.apple.com (developer beta), then pick the beta channel on your device under Settings > General > Software Update > Beta Updates.
Is the iOS 27 developer beta free?
Yes. Since 2023 anyone with a free Apple Account can install developer betas — a paid Apple Developer Program membership is no longer required. Enroll at developer.apple.com with your Apple Account, then enable Beta Updates on your device.
What is the difference between the developer beta and the public beta?
Developer betas arrive first and are the least stable. Public betas follow roughly a week later, usually matching an earlier developer build with critical fixes. If you use your device daily, choose the public beta — or wait for the Release Candidate (RC).
Can I go back to the stable release after installing a beta?
You can switch Beta Updates back to Off and wait for the next stable release that has a higher version number than your beta. To downgrade immediately you must restore the current stable IPSW with a computer, which erases the device — so always make an archived backup before installing any beta.
Will installing a beta delete my data?
An over-the-air beta update keeps your data. The risk is going back: a backup made on a newer iOS version cannot be restored to an older one. Make a local (archived) backup on your computer before you start, and keep it.
Which devices support iOS 27?
iOS 27 supports iPhone 11 and later, including iPhone SE (2nd generation) and the whole iPhone 12–17 range. iPhone XR, XS and XS Max are not supported. See the full compatibility list on our Supported Devices page.
What is an IPSW file?
An IPSW is Apple's full firmware package for a device. You can use it with Finder (macOS) or Apple Devices (Windows) to clean-install or downgrade a specific build instead of updating over the air.
How do I stop getting beta updates?
Go to Settings > General > Software Update > Beta Updates and select Off. Your device stays on the current build and will move back to the stable channel with the next public release.
