Following the October 6 release of developer beta 2, Apple is now rolling out macOS Tahoe 26.1 beta 3. Here’s what to expect from this release.
Setting the stage for new AI features
The first two betas of macOS Tahoe 26.1 brought interesting under-the-hood improvements, including the first steps of MCP adoption across all operating systems, as well as initial support for third-party models in Image Playground beyond ChatGPT.
