MacOS 27 Drops Support for All Intel Macs, Ending Five-Year Transition

What You Need to Know
- Apple ended Intel Mac support; only Apple Silicon Macs receive major macOS updates now.
- Siri now powered by Google’s Gemini, routing requests through Spotlight with on-device and cloud processing.
- Liquid Glass refinements add transparency intensity controls and standardized window corner radii across macOS.
- Rebuilt search architecture improves Spotlight and Finder file discovery, underpinning new Apple Intelligence features.
Apple’s first Intel-free macOS release is the real story in Golden Gate 27, even though the company buried it beneath a long list of AI features and interface tweaks.
Every Mac running an Intel chip is now officially cut off from major macOS updates. Apple Silicon launched in late 2020, which means the transition window lasted roughly five years, shorter than the PowerPC-to-Intel shift that took about the same time but was managed with Rosetta compatibility layers that softened the blow. Intel Mac owners who bought machines as recently as 2020 are now on a dead-end branch of the OS.
The AI additions are real, though the framing around them requires some patience. Siri is now powered by Google’s Gemini, which is an unusual sentence to write about an Apple product. Apple is routing AI requests through Spotlight and handling conversations in a dedicated window where users can drag files for analysis, combining on-device processing with cloud models.
Liquid Glass and Search
The Liquid Glass refinements are Apple quietly acknowledging that macOS Tahoe shipped with a half-finished visual system. Users now get intensity controls for the transparency effect, standardized window corner radii, and more consistent iconography across the OS. That these are listed as features in a new release rather than patches to the previous one says something about how Apple manages its software cadence.
The rebuilt search architecture is the less glamorous but more practically useful update. Spotlight and Finder missing files and apps has been a persistent complaint across several macOS versions, and Apple says the new indexing foundation also underpins the Apple Intelligence features arriving this cycle.
Safari’s AI-generated extensions are the sleeper feature here. Describing what you want in plain language and having the browser build the extension automatically collapses a barrier that previously required JavaScript knowledge, which could meaningfully expand who actually customizes their browser.
