The parent comment was talking about Docker desktop, which is clearly targeted at macos and windows. Saying that you can just download it with an apt command is irrelevant to the discussion, because we can't use that outside of linux.
I didn't know what it was, so I didn't know it was only for macos and windows. If instead of being sarcastic he had just answered my question, I wouldn't have said something irrelevant.
You asked a question which literally has no relevancy to or answer in macOS. There is no apt. There is no default package manager. There is no equivalent command to run on a new system.
If you wanted a real answer, you should have asked a real question. Something like, are there any options other than docker desktop for macOS?
Nobody is talking about that question. You received an answer to it already:
> The thing that I have to install on MacOS so that I can run docker. Is there any other way(i.e no gui utility) ?
We're talking about your subsequent reply asking a further question. A question that has no relevancy to or answer for macOS for reasons already discussed. As I said before, if you wanted a real answer then you should've asked a real question.
> Pro-tip Remove that keybase from your profile, you look ridiculous.
Nobody asked for your unsolicited advice or opinions regarding Keybase or ones' use of it in their profile, thanks.
There is no apt on macOS.
