Prepare your computer
If you don't have these things already installed, you'll need to do this before you can get Firefox OS running.
- Install XCode from the Mac App store.
- Once it's "installed" from the App store, open the app to finish the installation.
- Then, open the XCode preferences and install the Command Line Tools.
- Finally, download and install Git from http://git-scm.com/downloads
Get the Boot2Gecko app
- Download the latest nightly build from ftp.mozilla.org. You want the latest mac64.dmg file.
- Double-click the .dmg file you just downloaded to open it and then drag the B2G.app to your Applications folder.
- First, create a folder to hold everything. For these instructions, we'll create a "FirefoxOS" folder in your Documents folder.
- Open up the Terminal application. You automatically start in your Home folder (username:~).
- In the Terminal window, switch to the FirefoxOS folder you created in step 1 by typing, cd Documents/FirefoxOS and then hit
- Next, clone the Gaia repository (in English that means, download a copy to your computer) by typing, git clone https://github.com/mozilla-b2g/gaia gaia and then hit
