We strongly recommend installing on a secondary system or device, or on a secondary partition on your Mac. Install the beta software only on non-production devices that are not business critical. Since Apple TV purchases and data are stored in the cloud, there’s no need to back up your Apple TV. Be sure to back up your iPhone, iPad, or iPod touch and your Mac using Time Machine before installing beta software. Please note that since the public beta software has not yet been commercially released by Apple, it may contain errors or inaccuracies and may not function as well as commercially released software. On the website where Apple offers the public beta programs for iOS 15, iPadOS 15, and tvOS 15, it has a warning that betas will contain bugs and errors and should not be installed on primary devices:

Having a recent backup ensures that if you need to downgrade to iOS 14 or iPadOS 14, you’ll lose as little data as possible. You can find out the details on how to back up your iPhone and iPad right here in our full guide. Consider trying on a spare device firstįirst and foremost, before you consider installing the iOS 15 and iPadOS 15 public betas on your devices, be sure to make sure you have a recent backup.
