Install iOS 12 Public Beta
Once you’re set up in the Apple Public Beta Program and have backed up your device, you will need to enroll your device. To do that, from your iPhone or iPad, go to beta.apple.com/profile and log in with your Apple ID. Then tap on the “Download Profile” button and “Allow” to the message that pops up about the site trying to open Settings.
Next, tap the Install button, agree to the terms, and a restart will be required.
Once you get back from the restart you’re ready to get the update. Go to Settings > General > Software Update and tap Download and Install and agree to the terms. Then the update process is just like any other iOS upgrade you’ve done before. It will take a while as the upgrade installs and your device will restart a couple times.
Once installed, you will need to go through some initial set up steps like creating a passcode and getting introductions to some of the new features in iOS 12. Once you navigate through those steps, you’ll be brought to the home screen and you’re ready to start using iOS 12 on your phone or tablet. The new Public Beta Program features the new versions of iOS 12, tvOS 12, and macOS Mojave. Apple’s new watchOS beta isn’t available in the public program, however. It’s only for developers.
