You need to put a lot more context into this issue.

I have no idea what kind of code I should write to implement this 😄

Just reopen this issue if you add more context to your description.

I want to run this great project on a macOS host, and I want my ci files to be executed by the tart executor, that is, to run the ci script in a macOS virtual machine driven by tart, instead of docker or shell. I don't know how to do this at present. Can existing projects accomplish this goal? If not, how should we support this.

Since the issue was closed by the repo owner, who is you, I can't re-open it anyway.

Supporting these custom executors is going to be a major undertaking.

I'm not going to work on this, but we will leave this open in case others want to implement it.
