The steps you need to complete to install the software on your device are provided towards the end of this article, but before you jump ahead, here are a few things worth considering.

Should I Install iOS 18 Public Beta?

Before downloading the update, it's worth noting that Apple does not recommend installing the iOS 18 Beta on your main iPhone, so if you have a secondary device, use that. This is beta software, which means there are often bugs and issues that pop up that can prevent software from working properly or cause other problems. If you're concerned about potential issues, hold off on installing and wait for Apple to launch its final stable release later this year.

Make an Archived Backup of Your Device First

Before installing the beta, make sure to back up your iOS device before installing the software using the following method, otherwise you won't be able to revert back to iOS 17 if things go wrong.

1. Plug your iPhone into your Mac using the supplied cable.
2. Allow the accessory to connect by clicking Allow in the dialog prompt.
3. Open a Finder window by clicking the Finder icon in the Dock.
4. Click your iOS device's name in the sidebar.
   
   

5. If this is the first time connecting your device to your Mac, click Trust in the Finder window.
   
   

6. Tap Trust on your device when prompted, then enter your passcode to confirm.
7. In the General tab, click the circle next to where it says Back up all of the data on your iPad to this Mac.
8. If you want to encrypt the backup, check the box next to Encrypt local backup, then enter a password to protect your data.
9. If you don't want to create an encrypted backup, or you've already set up encrypted backups, click Back Up Now. When the backup is finished, you can find the date and time of the last backup in the General tab, just above the Manage Backups button.
   
   

10. Lastly, archive the backup: Select Manage Backups ➝ Select Backup, then right-click the backup and choose Archive.

Remember that this backup will not be overwritten when you manually or automatically back up your iPhone in the future, so you can restore it at any time by using the Restore Backup... option in the same Finder screen.

How to Download iOS 18 Public Beta

1. On your iOS device, open up Safari and navigate to the Apple Beta Software Program website.
2. Tap the Sign up button and enter your Apple ID credentials, or sign in with your Apple ID if you've signed up to beta test a previous update.
3. Agree to the Apple Beta Software Program terms and conditions if required.
4. After signing in, you'll see a main screen that's a Guide for Public Betas. Click on iOS (or iPadOS if you're installing on an iPad).
5. Read through Apple's instructions carefully, and then using the link in the "Get Started" section, select enroll your iOS device.
6. Make sure to make an archived backup of your current version of iOS using Finder by following Apple's instructions or using our tutorial above. This will allow you to downgrade back to iOS 17 if necessary and is crucial if you don't enjoy the iOS 18 testing experience.
7. Now on your iOS or iPadOS device, go to Settings -> General -> Software Update -> Beta Update, then choose the iOS 18 public beta you'd like to install.
8. Once the beta update has been downloaded you can tap Install Now to get it set up, and from there, the iPhone will install the software, restart, and you'll be up and running with the iOS 18 software.

Open Settings, tap the profile and follow the onscreen instructions to allow installation.
