Steam is adding native support for Macs with Apple Silicon chips, eliminating the need for Rosetta 2 emulation, which should improve performance and compatibility on M-series Macs.
Apple announced that macOS Tahoe 26 will be the last update supporting Intel-based Macs, as support for these devices will end with macOS 28, with only limited Rosetta 2 functionality remaining for older apps. Full support for Intel Macs will cease next year, but security updates will continue for three more years, marking the end of an era as Apple fully transitions to its custom silicon.
Apple will end support for Intel Macs with the release of macOS 27, which will be the last to support Intel models, and will phase out Rosetta 2, limiting its use to older, unmaintained apps, encouraging developers to transition to Apple Silicon-native or universal apps. Support for macOS Tahoe will continue until fall 2028 with security updates.
