Apple to Name Next macOS 'Tahoe,' Switch to Year-Based OS Names Like 'macOS 26' [Report]

Apple's next major macOS release is reportedly set to be named "Tahoe," and the company is also planning a wider shift to year-based branding for all its operating systems, such as iOS 26, according to Mark Gurman. In his latest newsletter to subscribers, Gurman outlined these upcoming changes, expected to be officially unveiled at WWDC.

Apple has been naming its Mac software after California locations since 2013, with Mavericks being the first. Tahoe would continue this tradition. Gurman points out that significant macOS redesigns often get iconic names like Yosemite (for a major visual change) and Big Sur (accompanying the shift to Apple silicon). With another substantial visual overhaul anticipated for macOS 26, "Tahoe" would fit the bill. The name, evoking the famous lake, might also hint at the "striking visuals of the new user interface."

Gurman also elaborated on the move to year-based OS names like iOS 26 and macOS 26, a strategy he previously reported. This change is intended to create more consistency and simplify versioning for users and developers, especially as Apple aims for a more cohesive software experience with its upcoming "Solarium" interface.


As for why Apple would choose "26" for software releasing in 2025, Gurman offers a few insights. It could signal that the platforms will evolve with more frequent updates throughout the year, rather than a single large fall rollout. New operating systems typically launch in September, meaning they are only available for a few months of their announcement year, and Apple's fiscal year 2026 also begins in October. Gurman also suggests that "26" simply sounds more futuristic, potentially helping Apple shift the narrative as it works to advance its AI capabilities. If this strategy holds, "27" branded operating systems would likely be unveiled next June.

These announcements are expected at Apple's Worldwide Developers Conference, which kicks off June 9. However, Gurman is skeptical that Apple will apply a similar naming change to its hardware, such as renaming the iPhone 17 to "iPhone 26." He believes the current iPhone numbering is too familiar to consumers and that tying hardware to a specific year could make older devices seem outdated more quickly.
