That's merely the mechanism to enable running Intel software. Many of the system frameworks and a few of the built-in application extensions are universal binaries, so there's quite a portion of Intel code installed on the system.
Same thing happened with the PPC transition; 10.4.5 to 10.5.8 had a lot of PowerPC code even without Rosetta installed.
- djxfade 3y agoWhich makes sense, since users have come to expect software to be portable. Let's say you have an Intel machine, and an Apple Silicon machine. You could then install software to a portable USB drive, and run it on both devices.
- lapcat 3y agoThe Signed System Volume is exactly the same everywhere, on Intel and Apple Silicon Macs. It doesn't selectively install architecture-specific binaries. The "personalization" is basically firmware updates specific to your Mac. These are a lot bigger and more complicated on Apple silicon than on Intel. You can see this with the --downloadassets argument to the createinstallmedia tool: https://scriptingosx.com/2018/10/include-assets-in-external-macos-installer-drives/ https://scriptingosx.com/2018/10/include-assets-in-external-... The same thing happens with iOS updates.
- zapzupnz 3y ago> It doesn't selectively install architecture-specific binaries. I know, I didn't say otherwise. I said the system is universal. I wasn't even talking about the updated mechanism.
