# OS X 10.10 Guide

Here's what I did to get things working.

### 1. Install Xcode 6

Yep, over at: https://developer.apple.com

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

### 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 at Ruby 2.0

It looks like Homebrew somehow depends on Ruby being in `Versions/1.8` (though even Mavericks ships with 2.0). Until Homebrew addresses this, we'll symlink our system version of Ruby to the one Homebrew looks for.

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...). Along with `rbenv`, etc.

You'll probably need to install Bundler with `gem install bundler` if you haven't already.

## Improve this Gist!
