Apple Intelligence will be switched on by default, starting in iOS 18.3, iPadOS 18.3, and macOS 15.3. In release candidate notes spotted by 9to5Mac, Apple says it will switch on AI-powered features automatically for new users or those upgrading to the latest versions of its operating systems.

The AI update will only apply to devices that support Apple Intelligence, including the iPhone 15 Pro and later, iPads and Macs with the Apple Silicon M1 chip or later, and the most recent version of the iPad mini.

For users new or upgrading to macOS 18.3, Apple Intelligence will be enabled automatically during Mac onboarding. Users will have access to Apple Intelligence features after setting up their devices. To disable Apple Intelligence, users will need to navigate to the Apple Intelligence & Siri Settings pane and turn off the Apple Intelligence toggle. This will disable Apple Intelligence features on their device.

As Apple’s notes mention, after updating your device, you’ll have to manually disable Apple Intelligence if you don’t want support for features like AI notification summaries, Image Playground, and tools that can rewrite pieces of text running on your device. To turn Apple Intelligence off, you’ll have to head to the Apple Intelligence & Siri Settings pane and then switch off the Apple Intelligence toggle.

Last week, iOS 18.3 beta testers spotted an update that will pause AI notification summaries for news and entertainment apps after the feature inaccurately summarized a BBC headline. Apple will also make it easier to identify notification summaries on your iPhone’s lock screen and note that they “may contain errors.”
