Check the ‘About Xcode’ readme:
Uninstalling Xcode Developer Tools
To uninstall Xcode developer tools on the boot volume along with the directory, from a Terminal window type:
To remove the underlying developer content on the boot volume, but leave the directory and supporting files untouched, from a Terminal window type:
To just remove the UNIX development support on the boot volume, but leave the directory and supporting files untouched, from a Terminal window type:
Finally, to just uninstall the directory you can simply drag it to the trash, or from a Terminal window type:
NOTE: The uninstaller that ships with previous versions of the Xcode developer tools will not clean everything off of your system properly. You should use the one installed with these Xcode developer tools.
If you find a black hole with the above, you could always reinstall Xcode, with those tools deselected and then delete according to the above, but all bets are off at that point, sorry 🙂
How do I manually uninstall the Developer Tools?
I installed the Developer Tools way back in Tiger or Leopard and I’d like to uninstall them now. I have Xcode 4.0.2. How do I uninstall them manually?

Yes, simply run the following in Terminal:
Where is the default installation of Xcode, typically:
Based on your OP, I am assuming you are running pre-Lion Xcode. This is covered in the documentation that comes with the Developer Tools install:
/Developer/About Xcode
NOTE: The uninstaller that ships with previous versions of the Xcode developer tools will not clean everything off of your system properly. You should use the one installed with these Xcode developer tools.
Pleae super-double check that this documentation either exists with your installation or is the same as your installation before you act. As with any such commands, precision and compatibility are critical.
It looks like you just have to remove the /Developer folder (especially if you have already installed version 4.3 or later of Xcode). The Xcode section of the Apple Developer Support Center actually tells you to do this (emphasis mine).
I’ve installed the latest version of Xcode from the Mac App Store, but a previous version of Xcode (4.2.1 or earlier) keeps launching. What should I do?
To run the latest version of Xcode, make sure you are launching Xcode.app from the Applications folder. Xcode 4.3 and later is packaged on the Mac App Store as a single application and installs in your Applications folder as Xcode.app.
Previous versions of Xcode placed the tools and frameworks in the Developer folder. You can delete the older version of Xcode by dragging the Developer folder to the trash.
This is reiterated in New Features in Xcode 4.3 (emphasis mine).
The simplification afforded by repackaging Xcode 4.3 as a single app bundle eliminates the need for the /Developer directory containing prior versions of Xcode. As a result, the Install Xcode application and the uninstall-devtools command line script are also no longer needed.
Note: The first time you run Xcode 4.3, you are prompted with a dialog to delete the Install Xcode application from the Applications directory if one is resident, and to remove any older installation of Xcode (Figure 4). These actions are optional, Xcode 4.3 can co-exist with older installations of Xcode on the same Mac. Some operations may require an administrator password to enable them if you switch from one version of Xcode to another.
Figure 4 Option to remove older versions of Xcode
If you choose not to delete these items on the first launch of Xcode 4.3, you can remove the /Developer folder and the Install Xcode application by dragging them to the Trash at any time.
Установка и работа с менеджером пакетов для Maс OS X (MacPort и Homebrew)
Менеджер пакетов в Mac OS X позволит нам легко работать с пакетам посторонних разработчиков. В этом топике рассмотрим два таких менеджера: MacPort и Homebrew.
1. MacPort
Официальний сайт
На этом же сайте можна найти Mac OS X Package (.pkg) Installer для Mountain Lion, Lion, Snow Leopard и Leopard. Установите подходящий вам пакет и пользуйтесь на здоровье. Есть и другие способы установки, но мы выбрали простой и быстрый. На случей чево, у меня port установился сюда: /opt/local/bin/port.
Требование:
Работать с port придельно просто — ищем в «портах» нужный пакет и устанавливаем его:
Дополнительные команды:
2. Homebrew
Официальная страница
О Homebrew поговорим подробнее…
Требование:
Установка:
После успешной установки виполним следующую команду:
Если в результате этой команди получим ответ: «Your system is raring to brew», тогода все хорошо и можете спокойно начинать работу з brew. В ином случае продолжим…
Если возникла ошибка Warning: Experimental support for using Xcode without the «Command Line Tools», то скорее всего была обновлена «ось», к примеру, с Lion к Mountain Lion, но не была переустановлена Command Line Tools для Xcode.
Если возникла ошибка Error: No such file or directory — /usr/local/Cellar, то нужна создать эту директорию:
После этого опять запускаем команду:
Если мы получим что-то вроде этого:
то исправляем примером так:
Если на этот раз никаких ошибок не произошло, тогда все — можна спокойно работать с Homebrew.
Удаляем сторонние приложения в «Системных настройках» на Mac
Некоторые сторонние приложения при установке создают собственные элементы меню в «Системных настройках» — ради удобства пользователя. С помощью них можно легко настроить или обновить программу, причем сделать это гораздо быстрее, чем обычно. Однако, если вы не хотите видеть подобные пункты в меню настроек, их можно удалить или скрыть. Рассмотрим подробнее этот процесс.
Для удаления значка зажимаем клавишу Command и выбираем программу. Должно появиться меню с опцией удаления.
Если этот метод не подходит, то можно сделать это вручную.
Вот так просто можно удалить сторонние приложения в «Системных настройках» на Mac.

What is the Command Line Tools Package?
The Command Line Tools Package is a small self-contained package available for download separately from Xcode and that allows you to do command line development in macOS.
