Creating an AppleScript to Switch Between Multiple iTunes Accounts

Read Time:12 minsLanguages:


If you own an Apple device, you'll have an Apple ID which will also be your account for shopping in iTunes. Some Apple owners may have multiple Apple IDs: perhaps work, personal, for shared content with family members or even Apple IDs for iTunes stores in different countries.

If you have multiple Apple IDs that you use with iTunes, you'll already be familiar with the hassle of changing accounts frequently and having to type the credentials each time.

In this tutorial, I'll be showing you how create an AppleScript that enables easy switching, between all of your Apple IDs, with a single click inside iTunes.

Before We Begin

Before we begin, it is important to understand that this is an advanced tutorial using AppleScript. If you are unfamiliar with AppleScript, you are first advised to check out some beginner tutorial published on Mactuts+. I've listed them below.

1. The Aim

The aim of this tutorial is to code an AppleScript that enables you to:

  • save all your Apple ID accounts in a plist file
  • log in into iTunes using a registered account
  • delete all registered accounts

The script saves all of your Apple ID accounts in a plist file with following structure: each file row has as key a label that identify the account, and it has as value an array that contains the Apple ID email address and password.

Tip: Note that the password fields, in the plist file, are not encrypted. In order to protect this, it is recommended that you set up a password on your OS X user account. Consider setting up separate user accounts in OS X if you share your Mac with anyone else.

The image below shows an example of the plist file updated with two Apple IDs registered.

Accounts Plist file

If you are unfamiliar with plist files, I recommend you read the documentation about it on the Apple Developer site.

2. Launch the AppleScript Editor

Launch the AppleScript Editor app. You will find the application inside Applications > Utility. Alternatively, type the app name into Spotlight (or Alfred app) to launch it.

AppleScript Editor

The AppleScript Editor is your development environment where you can write, edit, compile and test your AppleScript code. Once you have opened the app you can start to write the script.

3. Begin Coding the Script

The script has some functions that simplify the main code so it will be more readable and clear. Let's code the functions.

Step 1

The first function allows the creation of a plist file which contains all of your Apple ID accounts. The code below defines the function.

The createAccountsFile(filePath) function has one parameter filePath which is the POSIX path of your plist file. Line 5 creates the Root dictionary and line 7 saves it to the new plist file.

Step 2

A second function allows you to add a new Apple account to plist file. The addAccount(filePath, label, email, pass) function has four parameters:

  • filePath is the POSIX path of plist file
  • label is a label to identify the Apple account
  • email is the email of Apple ID account
  • pass identifies the account password

The code below implements the function defined.

Step 3

The function coded below returns a list of all labels of each account. The getLabels(filePath) has one parameter only: the filePath that is the plist file POSIX path.

Step 4

Another important function is getAccountInfo(filePath, selectedAccount) that returns information (email and password) about a registered Apple account. The function below has two parameters:

  • filePath is the POSIX path of plist file
  • selectedAccount is the chosen account when you run the final script

The code below implements the function.

Step 5

The getPath(fileName) function coded below, implements a utility function that returns the absolute POSIX path of a file specified by the parameter fileName. In our case, the file name will represent the plist file with all Apple accounts.

Step 6

Finally, let's code the last function: the core function. It allows us to sign into iTunes, automatically, with any account registered in the plist file. The iTunesLogin(info) function has one parameter only: info represents an array which contains email and password of an Apple account.

To login to iTunes automatically, AppleScript language simulates the manual operations you would do to achieve the following:

  • Launch iTunes
  • Click on Store > Sign In…
  • Type your email
  • Type your password
  • Click on Sign In button

The function below does all steps above for you.

In this function, there are two global variables loginBtn and logoutBtn. They represent the buttons for signing into and signing out of iTunes. The button names are base on the system language; you have to set them correctly for the AppleScript to work.

4. AppleScript Main Code

Once you have finished coding all previous functions, you can write the main code of your AppleScript. Inside the AppleScript, place you cursor at the top of file.

Step 1

The first step to complete our tutorial is set some variables and do some checks.

Step 2

The next step is to display a dialog box which asks the user what they want to do? Our AppleScript has following features:

  • Choose Account (for iTunes sign in)
  • Add a new Apple Account (to the plist file)
  • Reset Accounts (empty the plist file)
Actions DialogActions DialogActions Dialog
Actions Dialog

The code below implements the dialog.

Step 3

Now it's time to parse the user choice.

If the user clicks on Add Account button the script ask to him to insert the credentials for a new Apple account. It will display three dialog boxes with input fields for account label, email and for the password. The code below implements this process.

If a user clicks on the Choose Account button, the script displays a dialog with all of the registered accounts. When the user chooses an account, the script runs iTunes login. Let's implement the action.

If the user clicks on the Reset Accounts button, the script overwrites the plist file with an empty one. The code below calls the createAccountsFile(filePath) function again to complete the process.

5. Run the Script Inside iTunes

The last task required, in order to finish the tutorial, is installing your AppleScript into iTunes so you can easily access it anytime it is required.

Step 1

First, export the AppleScript. Inside the AppleScript Editor app click on File > Export… from the top menu.

Inside the export panel you have to:

  • export as "Access To iTunes"
  • choose as location your Desktop
  • choose Script as file format
  • and select the Run-only option

When you are ready click the Save button.

Step 2

Now move the exported script into iTunes. To do that, launch Finder app and choose Go > Go To Folder from the top menu.

Complete the panel input field with /Users/Your.System.User/Library/iTunes/ and click on the Go button.

Now move the the Access To iTunes file from the Desktop to the Script folder (if this folder does not already exist, you will need to create it first) to complete the process.

Step 3

Another important step to ensure your AppleScript works correctly is to enable access to assistive devices: open System Preferences app, choose the Accessibility icon and check Enable access to assistive devices. The image below show the panel with this option.


Step 4

Now you are able to trigger the AppleScript directly from iTunes.

Congratulations! You have completed the AppleScript. If you have followed all of the steps you will be able to use the AppleScript from within iTunes. In this tutorial you have learned how to code an AppleScript, to switch between your Apple accounts, without having to repeatedly type in different email addresses and passwords. You can easily adapt this AppleScript to work with Mac App Store, too. Simply modify the iTunesLogin function. I hope you enjoyed this tutorial, let me know how you get on with the scripts and any comments or questions that you have using the comments section, below.
