Mac system is a very popular operating system among developers, and Git is the most well-known code version control tool. There are many benefits to using Git, such as facilitating multi-person collaborative development, version control, backup, etc. This article explains how to set up Git on your Mac.
1. Install Git
The Mac system does not have Git installed by default, so we need to install it manually. There are two ways to install Git:
- Installation through Homebrew
Homebrew is a package management tool under Mac OS X and also needs to be installed. Enter the following command in the terminal:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then enter the following command to install Git:
brew install git
- Download the Git installation package
From the official website [https:/ /git-scm.com/downloads](https://git-scm.com/downloads) Download the Git installation package, and then follow the prompts to install it.
2. Configure Git
After the installation is complete, we need to configure Git. You can enter the following command in the terminal for configuration:
- Configure user information
git config --global user.name "Your Name"
git config --global user.email "you@example.com"
- Configure text editor
git config --global core.editor "vim"
Above The command will set the default editor used by Git to Vim.
- Configure other options
You can use the following command to configure:
git config --global color.ui true
In this way, the information output by the Git command will be colored, which many people will think This makes it easier to distinguish.
3. Use Git
After the installation and configuration are completed, you can start using Git for code management. The following are some commonly used Git commands:
- Create a local code base
git init
Run this command in the folder to create a new Git code base.
- Add files to the code repository
git add filename
Add the specified file to the Git code repository.
- Submit code
git commit -m "commit message"
Submit the code and attach a submission message.
- View code base status
git status
View the current status of the code base, including modified but not submitted, submitted but not pushed, etc.
- View submission history
git log
View all submission records of the code base, as well as the specific information of each submission.
4. Summary
This article introduces how to install and configure Git on Mac systems, and lists some commonly used Git commands. For developers, Git is a very important tool. Learning to use Git can help us better manage code and improve development efficiency. If you haven’t used Git yet, do it now!

Git and GitHub are not the same thing: Git is a distributed version control system, and GitHub is an online platform based on Git. Git helps developers manage code versions and achieve collaboration through branching, merge and other functions; GitHub provides code hosting, review, problem management and social interaction functions, enhancing Git's collaboration capabilities.

After installing Git, in order to use more efficiently, the following settings are required: Set user information (name and mailbox) Select text editor Set external merge tool Generate SSH key settings Ignore file mode

Resolve: When Git download speed is slow, you can take the following steps: Check the network connection and try to switch the connection method. Optimize Git configuration: Increase the POST buffer size (git config --global http.postBuffer 524288000), and reduce the low-speed limit (git config --global http.lowSpeedLimit 1000). Use a Git proxy (such as git-proxy or git-lfs-proxy). Try using a different Git client (such as Sourcetree or Github Desktop). Check for fire protection

Causes of slow Git downloads include poor network connections, Git server problems, large files or large submissions, Git configuration issues, insufficient computer resources, and other factors such as malware. Workarounds include improving network connectivity, adjusting firewall settings, avoiding downloading unnecessary files or submissions, optimizing Git configuration, providing adequate computer resources, and scanning and removing malware.

How to update local Git code? Use git fetch to pull the latest changes from the remote repository. Merge remote changes to the local branch using git merge origin/<remote branch name>. Resolve conflicts arising from mergers. Use git commit -m "Merge branch <Remote branch name>" to submit merge changes and apply updates.

Steps to update git code: Check out code: git clone https://github.com/username/repo.git Get the latest changes: git fetch merge changes: git merge origin/master push changes (optional): git push origin master

You can delete a Git branch through the following steps: 1. Delete the local branch: Use the git branch -d <branch-name> command; 2. Delete the remote branch: Use the git push <remote-name> --delete <branch-name> command; 3. Protected branch: Use git config branch. <branch-name>.protected true to add the protection branch settings.

Git code merge process: Pull the latest changes to avoid conflicts. Switch to the branch you want to merge. Initiate a merge, specifying the branch to merge. Resolve merge conflicts (if any). Staging and commit merge, providing commit message.
