What iOS 26 RC 2 Is
iOS 26 RC 2 is build 23F77, released on May 8, 2026. A release candidate is the build Apple intends to ship. Unless something serious surfaces in the days that follow, this is the software that becomes the public release — see our explainer on what that means.
This is the first build of the iOS 26 cycle we have on record, which makes it the baseline every later build is measured against.
RC 2 Build Numbers Across Every Platform
Apple ships each beta wave across its platforms on the same day, usually with different build numbers per operating system. Here is every build we recorded in this wave, taken from Apple's own release feed rather than reposted from elsewhere.
Matching build numbers between two platforms — as iOS and iPadOS almost always have — mean they are built from the same source, which is why their betas behave identically.
| Platform | Version | Build | Released |
|---|---|---|---|
| iOS 26 | 26.5 | 23F77 | May 8, 2026 |
| iPadOS 26 | 26.5 | 23F77 | May 8, 2026 |
How to Install iOS 26 RC 2
There is no profile to download. Enrol your Apple Account free at beta.apple.com for the public beta or developer.apple.com for the developer channel, then open Settings → General → Software Update → Beta Updates and select the iOS 26 channel. The build appears in Software Update like any ordinary update.
If you are already on an earlier iOS 26 beta, this arrives as a normal update and no re-enrolment is needed. Our full iOS 26 install guide covers the process step by step, and our device pages tell you whether your exact model qualifies.
Should You Install It?
Yes, if you were ever going to. A release candidate is the lowest-risk point in the whole cycle: apps have caught up, the feature set is final, and in most cycles the RC and the public release are the same build with a different label.
Whatever you decide, make an archived backup on a computer first. A backup made on iOS 26 cannot be restored onto the previous release, so it is the only route back with your data intact — our backup guide explains the difference, and our honest assessment covers running a beta on the phone you depend on.
What Comes After RC 2
Beta 1 followed on May 26, 2026 as build 23G5028e. If you are reading this on RC 2, that newer build is already waiting in Software Update.
Our build history tracks every iOS build with its date and the gap before it, which is the clearest picture of how a cycle is progressing. The beta calendar guide explains the shape of the year.
