Prepare your device, backup and essential apps before installing Apple’s major software updates.
Confirm compatibility and backup
Check the exact device model against Apple’s supported-device list. Make a current backup before starting.
Check critical apps
Update essential apps and check guidance for work, banking, authentication and accessibility tools before upgrading a device you depend on.
Prepare the installation
Leave enough free storage and use reliable power and connectivity. Follow the update instructions shown by your device.
After upgrading
Review privacy permissions and notifications. Apple Intelligence and Siri AI availability can vary by device, language and region. This checklist is preparation advice, not a hands-on compatibility test.
Go straight to the people who make it.
