macOS 26, also known as macOS Tahoe, was officially released on September 15, 2025. This version represents the new naming scheme Apple adopted, where the macOS version number is based on the following year of its release. macOS Tahoe features a significant redesign with Apple's new Liquid Glass material design, and it is the last macOS version to support some Intel-based Macs. The release was aligned close to the launch of new iPhone models in September 2025, continuing Apple's tradition of timed software updates across its platforms.
