Apple’s not too long ago announced transition to Apple Silicon (Arm) primarily based Macs raised some fascinating questions on future help for these outdated machines.

Particularly, MacRumors discussion board member Wowfunhappy asked about ongoing support for Common binaries within the upcoming Arm-based macOS, and whether or not or not a four-way common binary was potential:

Throughout their 2020 WWDC keynote, Apple introduced the reintroduction of Common Binaries, for builders to create apps that work on each Intel and Arm Macs through the transition.

However Common Binaries by no means actually went away the primary time! You may run PPC-Intel apps on Mojave, and I assume additionally Catalina. Additionally, many Intel-only apps are nonetheless “common,” in that they comprise variations for each i386 (32bit Intel) and x86_64 (64bit Intel).

Thus, I’m intensely curious: wouldn’t it be potential for a developer to create a single common binary that works natively on all 4 architectures: PPC, i386, x86_64, and ARM?

The reply, it seems, is sure. The TenFourFox developer blogged about the possibility, confirming that it’s certainly potential:

A query I acquired repeatedly the final couple days was, now that AARM (Apple ARM) is a factor, is the final word ARM-Intel-PowerPC Common Binary potential? You wager it’s! Actually, Apple already paperwork that you could have a five-way binary, i.e., ARM64, 32-bit PowerPC, 64-bit PowerPC, i386 and x86_64. Simply construct them individually and lipo them collectively

TenFourFox is a Firefox port for PowerPC Macs working OS X 10.four or 10.5. It supplies these customers with a contemporary browser help. The developer really factors out that every structure may even have their very own subtype, which means that in the end a so referred to as “Tremendous Duper Common Binary” might have help for 17 completely different instruction units, which might run on any machine from PowerPC to future Arm-based Mac with full help for all processor subtypes.
