Installing Xcode

We’ll be using Apple’s development tool named Xcode this semester. If you want to use it on your own Mac you will need to install it wherever you want to use it. If you are using the classroom Macs and those in room B2216, you don’t need to do this.

OS X Mavericks

  1. The first step is to determine what version of OS X you are running. Click on the Apple menu and select About This Mac.

  2. Check the version number, it must be 10.9.1+ for this semester.

  3. If you have 10.9 then you need to update your version of the OS. Click on the Apple menu and select Software Update… and follow the directions you will see.

  4. If you have a version of OS X that is less than 10.9 you will need to install the latest version. The first step is to back up your computer! There is very low risk that anything will go wrong with this update. However, the risk is not zero and you need to have a backup just in case. Once you are backed up then proceed. Don’t skip this!
  5. Launch the application named App Store.
  6. Search for OS X and install OS X Mavericks. It’s free!


  1. Launch the App Store application.
  2. Search for Xcode. Install Xcode which is free, too. Yea!

  3. Xcode is very large and will take several minutes to download and install. It will be installed in the Applications folder. When it finishes installing, launch it.
  4. If you are presented with a dialog asking you to install more parts then go ahead and install everything.
  5. Open Xcode’s Preferences.

  6. Click on the Downloads tab.
