This morning, I decided to re-install MacOS High Sierra using macOS Recovery by pressing Command + r. The system got stuck when only 11 minutes were remaining.

I restarted it and did the same process again, only this time, it wanted to install OS X Mavericks. I continued installing it. Once OS X Mavericks was installed, I updated it to macOS High Sierra. It said it was installed but it was only downloaded.

I found it was downloaded in /Applications folder and did the install. Everything worked like it should.

I started to install Homebrew, but Command Lines Tools were not installed, and started installing it. Then I saw Command Line Tools update in the App Store, so I cancelled the one initiated by Homebrew and initiated installation from the App Store.

Now, in App Store, it keeps on showing update Command Line Tools for OS X El Capitan and macOS High Sierra.

What should I do?

Ignore the update shown in the App Store. Install Command Line Tools by running the command:

xcode-select --install

In case the command doesn't work, and gives an error stating,

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

simply run brew config. It will show a dialogue box asking to accept Xcode license terms. Once accepted, Command Line Tools will be setup successfully.

    Since I installed the command lines tools via App Store update, this command does not work. It says command line tools are already installed, use "Software Update" to install updates.

    Try running brew config and look for the value corresponding to CLT:.

    When I ran brew config, it asked to accept Xcode terms. Then the value next to CLT is 9.3.0.0.1.1521514116

    Bingo! CLT is now successfully setup on your machine 👍🏻. 9.3.0.0.1.1521514116 is the current version as of this writing. I have edited the answer to cover the discussed additional steps.

  • I have to run just update from another window "macos / preferences / software update" --- make no sense separate that "advanced instalations" from window "app store" --- "softwareupdate --install -a" stackoverflow.com/a/34617930/1347601
