Apple releases iOS 26.5 RC

Apple’s latest iPhone update is basically done. On May 4, Apple pushed the iOS 26.5 Release Candidate — build 23F75 — to developers, which is usually the last stop before the public version ships. That makes this less about flashy redesigns and more about what Apple decided was stable enough to lock in for everyone. And the standout change is not the wallpaper — it’s encrypted RCS messaging. ### What is a Release Candidate? A Release Candidate is Apple saying, “unless something breaks, this is the build.” It goes out to developers first so they can test apps against the near-final software and catch any last-minute bugs. Apple posted iOS 26.5 RC alongside RCs for iPadOS, macOS, tvOS, visionOS, watchOS, and Xcode, which is a strong signal that this release train is lining up for public launch soon. ### What’s the big change here? The load-bearing feature is end-to-end encrypted RCS messaging in Messages. That matters because RCS is the modern standard Apple uses for many iPhone-to-Android chats — the green-bubble conversations that already got typing indicators, better media handling, and read receipts in some cases. With iOS 26.5, Apple says those RCS chats can also get end-to-end encryption, though it’s still marked beta. ### Why is that a bigger deal than it sounds? Because encryption is the part that decides who can read the conversation. End-to-end encryption means the message stays scrambled from sender to recipient, instead of being readable in transit by the carrier or service operator. iMessage already works that way. RCS usually hasn’t — at least not between blue-bubble and green-bubble messaging. ### What’s the catch? Carrier support. Apple’s own wording says encrypted RCS will work with supported carriers and roll out over time. So even after iOS 26.5 ships publicly, not every iPhone user will see the feature immediately. This is more like Apple finishing its side of the plumbing than flipping one universal switch on day one. Didn’t this already show up before? Yes — and that’s part of why this RC matters. Apple had tested encrypted RCS during the iOS 26.4 beta cycle, but the feature did not make the final 26.4 release. Now it’s back in the official 26.5 RC notes, which is the clearest sign yet that Apple intends to ship it this time rather than quietly pulling it again. ### What else is in 26.5? The official RC notes are pretty thin on big consumer features. Apple lists some StoreKit changes for developers and one resolved wallpaper bug involving Unity and Kaleidoscope wallpapers failing to install or remove correctly. There’s also new system plumbing in Apple’s developer docs around accessory notifications — groundwork more than a headline feature for most users right now. ### So should regular iPhone users care? Yes — but mostly for privacy, not spectacle. If you message Android users a lot, iOS 26.5 could be the update that makes those chats meaningfully more secure. If you don’t, this is still the kind of point release you want: fewer bugs, a more finalized platform, and one important missing piece finally moving into place. ### Bottom line? iOS 26.5 RC looks like a classic late-cycle Apple update — small on the surface, but with one real upgrade hiding inside. The wallpaper chatter is fine, but encrypted RCS is the part that actually changes how iPhones talk to the rest of the smartphone world.
