Xcode

The first thing you should install is Xcode because it is the prerequisite for brew and many other development tools.

Xcode setup

Download and install it from the App Store or from Apple's website.

CommandLineTools

For installing Xcode command line tools, run:

xcode-select --install

It'll prompt you to install the command line tools. Follow the instructions and you'll have Xcode and Xcode command line tools both installed.

Verify installation of Xcode Command Line Tools

xcode-select -p

# You should see:
# /Library/Developer/CommandLineTools

Check that you can run git:

git --version
# You should see: (latest version)
# git version 2.30.1 (Apple Git-130)

Just to be certain, verify that gcc is installed:

gcc --version

If all went well, you should see the GCC version in the output.

It will show something like this:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 13.0.0 (clang-1300.0.29.30)
Target: arm64-apple-darwin21.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Developer Mode

Enable Developer Mode on this Mac so that you can use debugger and other dev tools

# check status
DevToolsSecurity -status
# DevToolsSecurity -status -verbose

#  substitute your username in palace of <username>
DevToolsSecurity -enable
# or
sudo dscl . append /Groups/_developer GroupMembership <username>

Work Directories

Go to terminal and run the following commands:

Create directories in user home

# Developer directory contains developer projects/code organized based on programming language 
mkdir ~/Developer
# Applications directory contains Apps you downloaded and install (VSCode, subllimtext, IntelliJ etc). 
# You don't need to have admin access to install apps into ~/Applications 
mkdir ~/Applications

# directory to install/copy developer CLI tools such as `gcloud` `appcli` etc
mkdir -p ~/Developer/Apps

mkdir -p ~/Developer/Work
# Make `web`, `go`, `java` etc directories under ~/Developer/Work:
mkdir -p ~/Developer/Work/tools
mkdir -p ~/Developer/Work/node
mkdir -p ~/Developer/Work/web
mkdir -p ~/Developer/Work/go
mkdir -p ~/Developer/Work/rust
mkdir -p ~/Developer/Work/java
mkdir -p ~/Developer/Work/python

Then you can check out your GitHub projects into respective directories

cd ~/Developer/Work/tools
git clone https://github.com/xmlking/macbooksetup.git
