Always wondered the same, re: updates. To be fair, macOS I believe is downloading an entire OS image each time. macOS is immutable root, like Fedora Silverblue, so OS updates download the entire OS image each time.

On a package-based system you're doing a diff update, essentially.

Then again, even Fedora Silverblue image updates don't take nearly as long as macOS.

At least both are better than Windows, god knows what's going on in Microsoft's update process.

Yeah, but the SSDs today can write something like 2GB/s, so even if you're re-writing the entire OS, you should be able to do that in what? 1 minute max?

Assuming they're using some fast parallel compression algo as well when unpacking it...
