What this means for you

If you still run Intel-only software on a Mac, Golden Gate 27 is the last macOS that will run it through Rosetta, so start planning the move now. Nothing in the release says what replaces Rosetta or how long it keeps working. If you have no Intel-only apps, nothing here requires action.

Apple has shipped iOS 27 and macOS Golden Gate 27, both carrying the company's Siri AI features and further changes to Liquid Glass. The only detail the source gives beyond that concerns Rosetta, the translation layer for Intel apps: Golden Gate 27 is the last version of macOS that will support it. The report runs to a single sentence past its headline, so there are no prices, device lists or performance figures to check, and no word on what runs Intel apps afterwards.
