Love to see upgrades with a negative net size lmao. Software should get more optimized with time, not more bloated. Oop, just got the gnome console popup notification saying that my install command finished running, sweet – it took as long as making this post
Back in the day there was a Mac OS update (Snow Leopard) that took gigabytes off. They dropped support for PowerPC CPUs. So the compiled binaries basically got slashed in half.

God, Snow Leopard was peak Apple.
Wait they pushed binaries for both architectures to everyone?
Yes. Thats how they made everything seem magical to the end user.
Two architectures, and two binaries in the single package.
All those programs that only had binaries in the old architecture ran through the emulator Rosetta.
Once the old architecture had been deprecated long enough, they dropped the PPC compilation in the binaries.
There was the technique to regain disk space by deleting the unused architecture binaries from the bundles.
I don’t know if that’s what they did for the PowerPC -> Intel switch, but now with the Intel -> ARM switch, Xcode compiler tools spit out dual arch binaries, so you can run the same binary natively on x86 or ARM. Things that aren’t compiled that way yet and only have x86 binaries, will be run using Rosetta 2.
Doesn’t matter much to the end user though. It’s all just pretty seamless if you’re on an ARM Mac and idk if there’s much or any problems on x86 Macs yet regarding binary compatibility. I actually doubt there is.
It was exactly the same.
Its why the Intel -> Arm is called Rosetta 2 and not Rosetta.
That OS was the last of Apple to come on optical media. So, no pushing. Buying physically.
It probably made the downloaded binary smaller, but the actual instal size for x86 machines probably didn’t change much.
…what?
We’re talking about the end of the transitional period from PowerPC (the G3 and G4 iMacs and iBooks) to the Intel architecture (about the time they went to the Macbook nomenclature). If I read this right, they didn’t push separate PowerPC and Intel architecture versions, you’d just get MacOS (or in those days, OSX) and it would ship with both binaries. Which, compiled binaries would be quite different for different architectures, data files, graphics, interpreted code etc. would be similar but pre-compiled binaries would be different.
I know for awhile a lot of applications were only available for PowerPC, so they did the Rosetta translation layer, which is a reason why you’d find PowerPC binaries on an Intel system. They did exactly that again with the transition from x86 to ARM.
I already responded to you in another comment, but:
No, it’s even crazier than that. You didn’t get separate PowerPC and Intel binaries either. You got fat binaries that had machine code for both architectures!
Might happen again one day if they decide to drop x86 support. Which they likely will.
in maybe 30 years, lol
idk, apple is very trigger-happy when it comes to discontinuing things (outside of the iphones, strangely.) i think by 2030 we will be long gone from apple x86 machines.
Well they haven’t made a single x86 machine in what, 4 or 5 years?
The 2024 version of MacOS doesn’t support anything older than 2017 and for most models it’s more like 2018-2020
I’d say in 2-3 years they’ll drop support for all x86 machines, at which point first party binaries can stop shipping with x86 code. Then eventually, several years later, they’ll drop support for x86 emulation via Rosetta 2, so that’s another thing they can drop from the OS. And once xcode stops giving you those fat dual-arch binaries, other software will also take a bit less space.
