BrewSetup for your DevSecOps Mac

Why spend time downloading pesky installers form the web, Just run this guy, grab a coffee and come back to a fully setup Mac for DevOps and Security testing

Approximate setup time is roughly 1-hour

The best bit about this, its idempotent so run it as many times as you like, it will know whats already installed and not install apps twice.

Preferences

Show Library folder

chflags nohidden ~/Library

Show hidden files

This can also be done by pressing command + shift + ..

defaults write com.apple.finder AppleShowAllFiles YES

Show path bar

defaults write com.apple.finder ShowPathbar -bool true

Show status bar

defaults write com.apple.finder ShowStatusBar -bool true

Disable unidentified developer warnings

sudo spctl --master-disable

Save Screenshots to alternative folder

I usually use this command after installing every application that I need - it keeps Apple applications on the first page and moves the rest to the next pages.

$ defaults write com.apple.screencapture location ~/Pictures/screenshots
$ killall SystemUIServer

Set Firmware Password

Setting a firmware password prevents your Mac from starting up from any device other than your startup disk. It may also be set to be required on each boot.

$ sudo firmwarepasswd -setpasswd

Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Turn Homebrew Analytics off

Homebrew now defaults to retrieving behavioral analytics tracking. Although anonymized, you may not want to participate in that. To disable the extra network traffic:

brew analytics off

Run the Brewfile

brew bundle #In the same dirctory you downloaded the source code into

Git config

Make sure to replace name and email with your personal details.

git config --global user.name "yourusername"
git config --global user.email "*.******@***.***"

ZSH config

oh my ZSH

sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

Lets change the theme now You can browse all the “Oh My ZSH” Themes here. To change the Theme, simply change the ZSH_THEME value in ~/.zshrc file from robbyrussell to Avit. Run the following command to update the config.

$ source ~/.zhrc

Lets add some backround config with Iterm

Open ITerm2 > Preferences > Profiles > Colors and change the background black color to use 20% gray

Install Powerline fonts

$ cd ~/.oh-my-zsh
$ git clone https://github.com/powerline/fonts.git

./install.sh

$ open ~/.zshrc
Set ZSH_THEME="agnoster" and save the file

Set Powerline font

You can set any Powerline patched font you like. All the fonts end with “for Powerline”.

Open ITerm2 > Preferences > Profiles > Text > Change Font and set it to “Meslo LG DZ for Powerline” font.

Install iTerm2 “color schemes” (

Download the iTerm2-color-schemes as a zip file and extract it

git clone https://github.com/mbadolato/iTerm2-Color-Schemes

The “Schemes” folder contains all the color scheme files — they end with .itermcolors

Open iTerm2 > Preferences > Profile > Colors > Color Presets > Import

In the import window, navigate to the “Schemes” folder

Select all the files so you can import all the color schemes at once Simply select whichever color scheme you like.

Select theme "Argonaut"

You should have a terminal that looks like this:

Add Syntax Highlighting

Clone the zsh-syntax-highlighting plugin’s repo and copy it to the “Oh My ZSH” plugins directory.

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

Activate the plugin in ~/.zshrc by adding `zsh-syntax-highlighting to the Plugins section as shown below.

Add ZSH-AutoSuggestion Plugin

This plugin auto suggests any of the previous commands. Pretty handy! To select the completion, simply press → key.

Install the plugin

git clone https://github.com/zsh-users/zsh-autosuggestions $ZSH_CUSTOM/plugins/zsh-autosuggestions

Open ~/.zshrc and add zsh-autosuggestions

Add Cowsay, Fortune and Lolcat

$ brew install cowsay
$ brew install fortune
$ sudo gem install lolcat

Then head into your .zshrc file and add the config to the bottom of the file

fortune | cowsay -f vader | lolcat

Pimp your NANO!

Why not use the best text editor with syntax highlighting for everything.

Simply take the below scripts, "touch" it into a "nano4upgrade.sh" and run it after a "chmod a+x"

Or just run it from within this repo

#!/usr/bin/env bash

# Install Nano (www.nano-editor.org) with syntax highlighting (MacOS)

VERSION="4.8"
NANO_SHORT="nano-$VERSION"
NANO_SRC="$NANO_SHORT.tar.gz"
NANO_URL="https://www.nano-editor.org/dist/v4"
NANO_EXTRA="https://github.com/scopatz/nanorc"

cd ~/
curl -Ok $NANO_URL/$NANO_SRC
tar -zxvf $NANO_SRC

mv $NANO_SHORT .nano && cd .nano/
./configure && make && sudo make install

git clone --depth=1 $NANO_EXTRA syntax_improved
cd ~/ && touch .nanorc

cat > .nanorc <<EOF
include ~/.nano/syntax/*.nanorc
include ~/.nano/syntax_improved/*.nanorc
EOF

rm -vf $NANO_SRC
printf "\nExit terminal and reopen to start using $NANO_SHORT\nTo uninstall it and revert to old:\ncd ~/.nano && sudo make clean uninstall && rm -rf ~/.nano\n"
exit
