Git Installation on macOS

Installing Git on macOS

This guide walks you through installing Git on your macOS machine for use with RStudio and GitHub. I recommend using Homebrew for the easiest installation.

!! At LJMU managed computers, install Git either from Company Portal or App Player (older).

Method 1: Using Homebrew (Recommended)

Homebrew is a package manager for macOS that simplifies software installation.

Install Homebrew (if not already installed)
- Open the Terminal application: Finder > Applications > Utilities > Terminal.
- Run the following command:
```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
- Follow the on-screen instructions, entering your macOS user password if prompted.
Install Git using Homebrew
- In the Terminal, run:
```
brew install git
```
- Press Enter to download and install Git.
Verify Installation in RStudio
- Important: Close and reopen RStudio (or its terminal pane) to update the PATH environment variable.
- Open a new terminal in RStudio: Tools > Terminal > New Terminal.
- Type git --version and press Enter. You should see the Git version (e.g., git version 2.43.0).

Method 2: Using the Official Installer (Alternative)

Download the Installer
- Visit the official Git website: https://git-scm.com/downloads.
- Click the “macOS” link and download the latest .dmg installer.
Run the Installer
- Locate the downloaded .dmg file and double-click it.
- Double-click the .pkg file in the opened window to start the installer.
Follow the Installation Wizard Prompts
- Click Continue through the steps.
- Enter your macOS administrator password when prompted.
Verify Installation in RStudio
- Important: Close and reopen RStudio (or its terminal pane) to update the PATH environment variable.
- Open a new terminal in RStudio: Tools > Terminal > New Terminal.
- Type git --version and press Enter. You should see the Git version (e.g., git version 2.43.0). ! If you want to copy and paste, but it doesn’t work with Ctrl + V or Cmd + V, use Shift + Insert, or Edit->Paste

RStudio, Git, and GitHub Workflow

To use Git and GitHub with RStudio, follow these steps:

Start/Update Project: Create or update an RStudio project locally.
Edit Code: Write or modify R code in RStudio.
Save & Stage: Save changes and stage them with git add.
Commit Changes: Commit staged changes with git commit.
Push to GitHub: Push commits to a GitHub repository with git push.
Sync with GitHub: Ensure the GitHub repository reflects local changes.
Pull Changes: Pull updates from GitHub with git pull.
