Install Xcode Command-Line Tools (macOS)

Many small macOS scripts and developer utilities rely on Apple's Command-Line Tools for Xcode package. Among other things, it ships:

• git, svn, and other version-control binaries

• clang & friends for compiling C/C++/Obj-C

• make, ld, strip, ar, nm, …

• SetFile, PlistBuddy, and dozens of helper tools used in shell scripts

If you ever tried to run git on a fresh Mac and saw a dialog asking to "Install Command Line Developer Tools", this is what macOS was talking about. Below are three quick ways to get them.

Time required: ≈ 2 – 3 minutes on a fast connection (700 MB download). No Apple-ID sign-in needed unless you prefer the full Xcode route.

1. One-liner in Terminal (fastest)

1. Open Terminal.app (⌘ Space → Terminal).

2. Run:

   xcode-select --install

3. A small dialog appears – click Install and accept the license.

That's it. After the installer finishes you can verify with:

xcode-select -p   # → /Library/Developer/CommandLineTools
clang --version    # should print Apple clang …

2. Via the full Xcode app (App Store)

Installing the full 20 GB Xcode bundle also drops the command-line tools on your system. Choose this path only if you plan to use the Xcode IDE.

1. Open the App Store and search for Xcode.

2. Click Get / Install (Apple-ID required).

3. Once Xcode finishes downloading, open it once so it can install its components.

4. Verify:

   xcode-select -p   # → /Applications/Xcode.app/Contents/Developer

3. Manual .pkg download (offline machines)

Apple hosts standalone installer packages on the Developer website:

1. Sign in at https://developer.apple.com/download/all/?q=command line tools (free account).

2. Download the DMG that matches your macOS version, e.g. Command Line Tools for Xcode 15.3.

3. Mount the DMG and double-click the .pkg inside.

Accepting the license non-interactively

Scripting a fleet of Macs? After installation run:

sudo xcodebuild -license accept

This pre-accepts the license so build systems won't hang waiting for T&C confirmation.

Uninstalling (rarely needed)

To remove the standalone tools:

sudo rm -rf /Library/Developer/CommandLineTools

Then reinstall with xcode-select --install whenever you need them again.

⚠️ Do not delete if they live inside Xcode.app – use Launchpad or Finder->Applications to remove Xcode instead.

Troubleshooting

• "Command line tools are already installed, use Software Update to install updates." – They're present; run softwareupdate -l to check for newer versions.
• xcode-select: error: command line tools are already installed, use Software Update to install – same as above.
• git: command not found even after installing – Open a new Terminal window or run hash -r to refresh your shell's path cache.

Wrap-up

You now have Apple's developer toolkit on your Mac. Most of the scripts in this repo (including the Hide Logic Extension helper) will "just work" from here on.
