Ho w to Install the iOS 11 public beta
Enroll your device
Go to beta.apple.com on the device on which you want to install the iOS 11 public beta, click iOS near the top of the page. Scroll down to the Get Started heading and then click “enroll your iOS device” in the text below it.
Back up to iCloud…
You’ll be reminded to back up. If you use iCloud Backup, open Settings and tap the row for your Apple ID at the top, then iCloud > iCloud Backup. Tap Back Up Now so iCloud records your device’s latest state, and let it complete.
…or iTunes on a Mac
To back up using iTunes on your Mac, follow the steps for preparing a device for a beta software update at
bit.ly/prepiosbeta – do not skip step 5, as you’ll need an archived backup if you want the option to roll back to iOS 10.
Download profile
Under the text of the second step on the web page, click the “Download profile” button. You’ll be taken to the Settings app and be shown a summary of the profile; basically, it tells your device to check for and receive beta updates.
Install and restart
Tap Install on the summary and read the reminder that what your device will receive is pre-release software. Tap Install again, then a third time on the confirmation dialog. When prompted to restart your iPad, tap Restart.
Get the beta itself
When your device restarts, go to Settings > General > Software Update and momentarily you’ll be told that your device is eligible to receive the iOS 11 public beta. Tap Download and Install, then follow the usual on-screen steps.
