It’s a package management system in the same way that Flatpack, yum, apt-get, snap and dozens of others are.

If you use MacOS and Linux, it’s not inconceivable that you might want to use the same package management system across both.

I’ve used it, didn’t particularly warm to it and didn’t install it on my most recent MacOS install after it shat all over itself on a previous installation.

I didn’t know that it was available for Linux. Not tempted to try.

I’m a firm believer in apt-get and failing that, Docker with side journeys into podman.
