Apple’s macOS 26 is set to be launched on June 9 at the annual Worldwide Developers’ Conference. However, owners of older MacBook Pro and iMac models will miss out on experiencing this next-generation operating system. The new version, which follows macOS Sequoia, is expected to be introduced alongside iOS 26, previously labeled as iOS 19. Both systems are anticipated to showcase user interface updates similar to visionOS, according to sources familiar with the developments.
Unfortunately, not all Mac users will benefit from the enhancements in macOS 26, codenamed “Cheer.” Reports indicate that Apple might discontinue support for several older Intel-based Macs. Pre-release versions of macOS 26 appear to be compatible only with specific configurations, including:
– MacBook Pro (2019 or later)
– MacBook Air (M1 or later)
– iMac (2020 or later)
– Mac Pro (2019 or later)
– Mac mini (M1 or later)
– Mac Studio (all models)
Models from 2018, such as the MacBook Pro and MacBook Air, as well as the 2017 iMac Pro and 2018 Mac mini, are notably absent from this list and are likely to lose support. However, the 2019 MacBook Pro and the 2020 5K iMac are expected to remain compatible.
Sources have accurately forecasted details regarding previous macOS and iOS versions, and they mention that the first developer beta of macOS 26 will likely be around 17 GB in size, slightly larger than macOS Sequoia. The naming of the new operating system continues to be uncertain, as some internal builds still show “macOS 16” in certain areas. Apple usually announces an official name during the WWDC keynote, traditionally opting for California-themed names. While current information suggests “macOS 26” branding exists, changes in nomenclature during development are not uncommon for the company.
The anticipated keynote on June 9, 2025, will unveil the next-generation operating systems to the public.
