- There are two tools that can be used to notarize a binary, both part of Xcode:
the old `altool` and the newer `notarytool` . `altool`
[was deprecated ](https://developer.apple.com/news/?id=y5mjxqmn ) by Apple.
`notarytool` requires Xcode 13+, and that in turn requires macOS 11.3+.

- Xcode CLI tools are sufficient for everything, except it is missing `altool` ,
We use the Xcode CLI tools as installed by brew. (version 13.2)
which is needed for the release-manager to notarise the `.dmg` .
- so full Xcode is needed, to have `altool` .
Sanity checks:
- however, brew now consider macOS 10.14 too old, and for some reason it
requires Xcode CLI tools. (`Error: Xcode alone is not sufficient on Mojave.`)
So, we need *both* full Xcode and Xcode CLI tools. Both with version 11.3.1.
The two Xcodes should be located exactly as follows:
```
