When is the iOS 27 RC (Release Candidate) released?

The iOS 27 Release Candidate is expected around September 7-9, 2026, shortly after the September 9 keynote. Apple has shifted the RC timing to be post-keynote rather than pre-on-sale — the RC ships after the "Surprise and Shine" event confirms the final iOS 27 feature set.

The exact RC time follows the same 10:00 AM Pacific convention as the public release. Developer beta 8 shipped August 31 (version 24A5430a), and the post-keynote RC is expected ~September 7-9.

For full RC details, see our iOS 27 RC release date FAQ.

Can I install iOS 27 before the official release time?

Only via the developer beta or public beta. If you are enrolled in the Apple Developer beta program or the Apple Beta Software Program, you can install the latest beta build now. The RC ships to developers before the public release, and the public release is the final build.

If you are on a stable public release version and want the official public release, you must wait for the 10:00 AM Pacific switch on September 14. iOS does not allow early installation of public releases — the update only appears in Software Update after Apple flips the global switch.

How long does the iOS 27 download and install take?

Plan for 1-2 hours total. The breakdown:

• Download: 6-7 GB over Wi-Fi. Takes 15-45 minutes depending on connection speed. iOS refuses to download updates above 200 MB over cellular.
• Install: 30-60 minutes. Your iPhone restarts 2-3 times. Do not interrupt the install.
• Total: 1-2 hours from tap to "Download and Install" to fully running iOS 27.

Charge your iPhone to at least 50% before starting. Plug in if possible.
