How to Install / Upgrade: Apple releases iOS 26.6.1 beta for iPhone, plus more

What happened

Apple released beta 5 for iOS 27 and companion updates, and also shipped a second wave of betas that includes iOS 26.6.1 for iPhone, macOS 26.6.2, and more, as reported by 9to5Mac. The second wave is a surprise on top of the main iOS 27 beta line, so devices may see more than one beta track depending on which program and build you are enrolled in.

The technical detail

To install or upgrade, enroll the device in the Apple Beta Software Program with the Apple ID you use on that device, then open Settings, go to General, and open Software Update. On iPhone, look for the iOS 26.6.1 beta or the iOS 27 beta 5 option that matches the track you joined, connect to power and Wi-Fi, download the update, and install it when the device is ready. On Mac, open System Settings, go to General, open Software Update, and install macOS 26.6.2 beta if it is offered for your enrolled Mac.

Market and competitive context

Gotchas include mixing beta tracks if you are already on iOS 27 beta 5 and then also expect the iOS 26.6.1 beta on the same phone without checking which profile or channel is active, and installing any beta without a current backup. Verify success by confirming the installed version under Settings, General, About on iPhone, or About This Mac on macOS, and by confirming Software Update no longer offers the same build after the install finishes.
