Although Apple did not mention release dates for its upcoming operating systems during its iPhone introduction, the company quietly added those dates to the associated Web pages for its core operating systems. We now know we can expect macOS 26 Tahoe, iOS 26, iPadOS 26, watchOS 26, and visionOS 26 to ship on 15 September 2025. I assume that tvOS 26 and HomePod Software 26 will ship simultaneously. Unlike with the last few major operating system releases, Apple isn’t indicating that any promised features will be postponed to later updates.
For everything except macOS 26 Tahoe, I recommend waiting a few days to make sure no unexpected bugs crop up. Then, upgrade when you have some time to explore the new features without pressure. With Tahoe, I urge more caution, particularly for production Macs, until you’re confident the software you rely on is compatible. Regardless, make sure you have a backup before upgrading any device.
