looks like apple wrote a native docker in swift

you can now run linux containers on your mac

... but it could be better.

what about (totally contrived):

  FROM apple/macos:10.11.6

  RUN xcodebuild -project myapp.xcodeproj -scheme MyScheme -configuration Release

Nice, but expect to page through a few pages of ToS during the build

lol

  ENV XCODE_FRONTEND=unattended
  ENV XCODE_LICENSES=accept,firstborn,applepay,appleid=sjobs@me.com

Close - but it would be more like this:

  services:
    macos:
      image: dockurr/macos
      container_name: macos
      environment:
        VERSION: "15"

(And indecently slow.)

> FROM apple/macos:10.11.6

Yeah I was working on that, created a prototype. I don't see a business in it, so abandoned.

It would be wonderful if this ran on older versions of macOS, but according to the README they only support 26.

you do not understand... Not run on, run IN :)

I'm saying the older version of macos could build/run INSIDE the container

just like on a ubuntu 24.04 system you can do:

  FROM ubuntu:16.04

  docker run ubuntu:16.04

and though I haven't tried it, I believe docker can do arm in x86 using an emulator (like rosetta)

You can already run older versions of macOS inside a VM on macOS.

So it seems like in theory that should be doable if someone just made the container images right?

Oh right. I don't see Apple having any interest in supporting that given their current trajectory.

i wish!
