# OS X 10.10 Guide

Here's what I did to get things working.

### 1. Install Xcode 6

Self explanatory.

### 2. Install the Command Line Tools (CLT)

Hit it: https://developer.apple.com/downloads/index.action?name=for%20Xcode%20-#

Make sure you get the package for 10.10.

### 3. Install Homebrew

Copy/pasted from the site:

```sh
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
```

### 4. Update the `brew` Script

Open up `/usr/local/bin/brew` with your favorite editor.

I had to comment out the brew system detection, so that the last 6-7 lines looked like this:

```sh
#BREW_SYSTEM=$(uname -s | tr "[:upper:]" "[:lower:]")
#if [ "$BREW_SYSTEM" = "darwin" ]
#then
#    exec "$BREW_LIBRARY_DIRECTORY/brew.rb" "$@"
#else
    exec ruby -W0 "$BREW_LIBRARY_DIRECTORY/brew.rb" "$@"
#fi
```

### 5. Point Ruby 1.8 to Ruby 2.0

_It looks like Homebrew somehow depends on Ruby 1.8 despite even Mavericks shipping with version 2. So until Homebrew fixes this, we'll symlink our system version of Ruby to the one Homebrew is looking for (in `Versions/1.8`)_

Create the folder:

```sh
sudo mkdir -p /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin
```

Then symlink the binary:

```sh
sudo ln -s /usr/bin/ruby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
```

### 6. Hack away!

My subsequent `brew install` commands seemed to work fine (`ruby-build`, `redis`, etc...)
