So whatever resources you have, Apple will use them mostly to render 3D glass effects. With Debian (Xfce), I can't speak for other desktop environments, you need roughly three times fewer resources to run the OS itself.
Actually, you don't have this choice anymore.
Apple is disabling downgrading across all of iOS, and starting to do the same with MacOS. So you need to keep old hardware to run older MacOS versions, and it's only a matter of a few years before Tahoe is the latest OS you can run on your Mac.
Oh, I must be clear here: I'm not considering M1 Macs or later, since Apple closed the ecosystem with Apple Silicon.
What you did is a downgrade in what's called the supported OS.
However, if you decide to downgrade to Catalina on an M1 Mac, it's not possible — Big Sur is the earliest version that runs on Apple Silicon.
Anyway, you cannot downgrade to a macOS version older than what your Mac originally came with. So if you buy a Mac now, Tahoe will be the minimum option.
Old Macs can certainly be downgraded. iOS doesn’t allow it though and they pulled the latest security update which fucking sucks. And if you buy a M5, Tahoe is the only OS that’s available.
That's a very temporary solution to be fair. KDE and even, shudder, Gnome put mac os and windows to shame when it comes to responsiveness, performance, and resource usage.
I mean, KDE does 3x the stuff for 1/3 the cost. That's more memory and CPU for your IDE or, more likely, chrome tabs.
Or you just don't run Tahoe?
