The OS 26.4 updates are loaded with security fixes, so grab it now
The iOS 26.4 update has a handful of neat new features and some bug fixes. There may not be the new Siri we were hoping for, but at least there are new emojis and a keyboard accuracy fix, right?
Well, even if you don’t care about any of that stuff, this is a must-install update. The Apple Security releases page lists almost 40 important fixes for security and privacy in iOS 26.4 and iPadOS 26.4. For macOS Tahoe 26.4, the list is even longer.
The bugs range from the relatively minor, like a fix in Crash Reporter that may allow an app to know which other apps you have installed, to the critical, like a security fix that prevents someone with local access to your device from accessing your Keychain items. There are updates to pre-installed apps, core components like networking, major WebKit vulnerabilities closed, and four kernel updates. Unless you have a very good reason not to, you should grab this update now.
Nothing here is known to be exploited in the wild, but we recommend all users update as soon as it is practical. To install OS 26.4 on your iPhone or iPad:
- Open Settings
- Tap General
- Tap Software Update
- Follow the on-screen prompts
