> the open source Docker alternative I was under the impression that docker was open source. I am mistaken?
Docker Desktop (the software people must use to run Docker under any Mac or Windows machines) is closed source.
Planning to buy a new MacBook for a family member I have some question to whoever is into the Apple wold: is that true that the next generation of MacBooks is going to have classic Esc&F# buttons, MagSafe, SD card reader and HDMI? When is it expected to be released? How is a MacBookPro better than a MacBookAir of the same specs (RAM&SSD)? We were going to buy a new MacBook now but the classic parts returning sound re…
We don't know anything for sure, only rumors: https://www.macrumors.com/guide/14-inch-macbook-pro/
Calling podman “the open-source docker alternative” is disingenuous. The Docker engine which it competes with is also open-source. The only closed Docker product is their desktop wrapper, for which podman is not an alternative. Podman people, you’re better than this.

... and podman is not an alternative for Docker Desktop.
... sure seems like it is: this handles QEMU setup/teardown with hardware virtualization support through Hypervisor.framework according to[0]. [0] https://twitter.com/simnalamburt/status/1434244533001224192
Idk why people keep pushing for this, on a personal dev machine, root is not a problem, and then there is QEMU
It's really bad UX.

The Docker CLI is also available for Mac, and is open-source.
Does that handle virtualization for you like this does? Is it distributed pre-built anywhere? I honestly looked just now and couldn't find anything.
Is there anyway to make docker-style Darwin containers?
I don't think Mac/Darwin has cgroups but it's based on BSD to it might have jails?

You can run docker on Windows without Docker Desktop. I think the only thing that requires Docker Desktop on windows is if you want windows containers, but I don't really think that's a common usecase.

I suspect the push for podman was more about how docker ignored CGroupsV2 for so long that Fedora eventually turned it on anyway which broke docker and then told users to switch to podman.
I think a really big part of it was where Red Hat asked Docker to accept their patch that allowed people to run docker with local registries only (no docker.io), and were told Docker would not be accepting that patch, and to go pound sand if they didn't like it (eh, so maybe not so forcefully). The first thing I tried to figure out when looking into Docker for work was how to limit the registries it would look at to…
