Colima is great. However, in the upcoming macOS 26 Tahoe, and mostly in macOS 15 Sequoia, Apple is beginning to provide a first-party solution:

I've been experimenting with it in macOS 15, and I was able to replace Colima entirely for my purposes. Running container images right off of Docker Hub, without Docker / Podman / etc.
(And yes, it is using a small Linux VM run under Apple's HyperKit.)
