On a related note, the other day I was on my brother's
10.14 mac, and I needed to migrate its macports from
a version for 10.13. There are instructions at that say:

  2.1.1. Install Xcode on OS X 10.9 or Later
  Download the latest version of Xcode from the Apple developer
  website or get it using the Mac App Store.

But the latest version of XCode is incompatible with 10.14,
and the Mac App Store won't install it (or any other version).
So those instructions might need an update. says:

  Install the latest version of Xcode that is compatible with your OS.
  Open the Xcode application once after installation and follow any prompts.

But it links to the page above, not to a page showing
the latest compatible versions of XCode for each macos

I'm sure I've seen such a list in the past, but can't
remember where it is, and I can't seem to find it today.
Is it somewhere prominent and I'm just not finding it?
It would be great if either of the above pages linked to it.

Ah, this has a great compatibility chart:

I know this thread is about letting people know that XCode
isn't always needed, but I think the instructions for getting
the right XCode for old macos systems could be better too.
