September is here, and with it, Apple’s latest iPhones and Apple Watches. At its Wonderlust event on September 12, Apple threw back the curtains on the new iPhone 15 lineup, Apple Watch Series 9, and Apple Watch Ultra 2. These devices all provide incremental improvements that make them attractive to people planning to purchase a new iPhone or Apple Watch, though they may not be irresistible upgrades for those still happy with older models. You can pre-order any of them starting September 15, with delivery and in-store availability on September 22.
Alongside the announcement, Apple revealed that iOS 17, iPadOS 17, watchOS 10, tvOS 17, and HomePod Software 17 will become available on September 18, with macOS 14 Sonoma arriving on September 26. Wait a week or two before installing this first batch of updates on essential devices to avoid any last-minute bugs, and hold off on Sonoma for a few months or until you’re confident your necessary Mac apps are compatible. Regardless of when you upgrade, make a backup right before in case an unexpected problem forces you to erase and restore.
