I recently upgraded my Mac to Sequoia 15.0 (24A335) so I had to upgrade Xcode & command line tools to 16. I need command line tools 15 also on the mac due to some of the legacy projects depending on it. I want to install command line tools 15 and choose it in the Settings-->Location, but Xcode doesn't display "Command line tools 15" although i download & install from https://developer.apple.com/download/all/

A command-line tools package has the same supported platforms as the associated Xcode [1]. macOS 15 only supports Xcode 16, and that means it only supports the Xcode 16 command-line tools. You may be able to install the Xcode 15 tools there, but it’s unsupported in the same way that Xcode 15 itself is unsupported.

If you need Xcode 15, or its command-line tools, it’s best to stay on macOS 14. Or do that work in a macOS 14 VM, which is typically how I deal with this sort of thing.

In addition to the above answer, the Command Line Tools pop-up menu in the Location settings only contains the name and build of every Xcode app installed on your system. It doesn't list any installed Command Line Tools package.
