How to Install the iOS 18 Public Betas
People with Apple developer accounts have had all the fun with the iOS 18 betas so far, but now that the public betas are out, anyone can try the new features. Setting up the public beta is slightly less involved than setting up the developer beta but just as free. And if you’re looking for help with the iPadOS 18 beta, you’re in the right place: the setup process is the same.
You should understand what you’re getting when you try a beta, though. For one, you won’t get all of the new features at once; many of them will come down the road. Also, the fun of trying features early comes with the potential thrill of stability issues and excessive battery drain. And it’s rare these days, but Apple’s betas can break things or potentially brick your device.
