How to download and install the iOS 15, iPadOS 15 and macOS Monterey public betas

Try Apple’s latest mobile OS before it’s released

Ever since WWDC 2021, you’ve wanted all those fab new macOS Monterey, iOS 15 and iPadOS 15 features for yourself. But Apple cruelly hasn’t supplied you with a TARDIS app, so you can zip to the autumn and install them. Bah. In fact: twice bah.

But wait! Because by way of the Apple Beta Software Program, anyone can get iOS 15 on to their iPhone, iPadOS 15 on to their iPad and macOS Monterey on to their Mac right now. But how? Here’s how.

How to install iOS 15 beta on your iPhone and iPad

1. Make sure your device is compatible. iOS 15 will run on anything that ran iOS 13 – so the iPhone SE, and the iPhone 6s/6s Plus or newer, along with the 7th-gen iPod touch. iPadOS 15 requires any of the following iPads: Pro (any); iPad 5th-gen or newer; iPad mini 4 or 5th-gen; iPad Air 2 or 3rd-gen.

2. Back-up the device you intend to install the beta on to, in case of disaster. Or don’t, but in that case don’t say we didn’t warn you. (Betas can be buggy.)

3. Head to on the relevant device, and sign up to the program. Or if you’re already signed up, sign in using your Apple ID.

4. Tap the relevant tab (iOS or iPadOS), scroll down to the Get Started section, and tap the ‘enroll’ link.

5. On the Enroll Your Devices page, scroll to the Install profile section and tap Download profile. You’ll be prompted to download a profile that will install into Settings. Head into General > Settings > Profiles, select the profile and tap Install.

How to install macOS Monterey on to your Mac

For the full ‘shiny new things’ experience, you might want to upgrade your Mac to the macOS Monterey beta. Although Macs remain very different from mobile devices, many of the same caveats apply when it comes to betas, notably that you’d need to have a few chairs missing to run beta software on a work-critical Mac. At the very least, make a back-up to safeguard your data.

Apple explains you can install macOS in a separate APFS volume, but the macOS Monterey beta release notes state this means your existing macOS install won’t receive updates. This suggests partitioning your drive is a smarter move. Apple outlines the process on its support site. You’ll need to use APFS format – and allow the new partition over 20GB of free space to be safe.

Install the macOS Monterey beta to that partition and then switch disks in System Preferences > Startup Disk or hold Option during start-up to select which OS to boot.
