Apple is planning to transition from macOS Sequoia 15 to macOS 26 for consistent OS updates, hinting at dropping support for certain Intel-based Macs.
The upcoming macOS 26 is reported to be incompatible with some Intel-based Mac models including 2018 MacBook Pro, 2020 Intel MacBook Air, 2017 iMac Pro, and 2018 Mac mini.
Rumored features of macOS 26 include a unified design across iOS, iPadOS, and macOS for a streamlined experience, along with advanced large language models for an improved Siri functionality.
The transition signifies Apple's focus on M-series lineup, with the expectation that eventually all Intel Macs will lose support to streamline the operating system ecosystem.
