An update to macOS 26.5 contains all the necessary code to update a Mac from 26.0 to 26.5 for both x86_64 and arm64 architectures.
- qsxfthnkp2322 5mo agoIs that an over the air update? Lol.
- atonse 5mo agoBut aren't they able to do incremental builds and separated x64/arm64? They know which OS version is requesting an update, at least the version number part.

During the PowerPC to Intel transition, they did stuff like that; perhaps at their current scale, there's reasons why they don't. Supporting both architectures enables a macOS install to boot an Intel Mac or an Apple Silicon Mac, which is useful in a dual-architecture environment. It's easy to check for dual architecture support; just use the file command: $ file /bin/ls /bin/ls: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit executable arm64e] /bin/ls (for architecture x86_64): Mach-O 64-bit executable x86_64 /bin/ls (for architecture arm64e): Mach-O 64-bit executable arm64e
