In order to get Stop Motion Studio Pro installed on your Mac/iPad, you will have to follow a few steps. What this does is set you up on the MacTech Mobile Device Management (MDM) System, which uses a tool called Mosyle. This will also distribute a license for the software using a "Managed Apple ID". Unfortunately, due to the way Apple has setup their license distribution system, it is not possible to access this from a personal AppleID. While inconvenient, this will at least keep licenses separated.
Once the course is over, your license will be revoked.
Step 1: Activating Your Managed AppleID
You should receive an email from "Apple School Manager" with the Subject "Set Up Your Managed AppleID". In that email it will provide you with a unique email address with the domain "@sheridancollegeca1.appleid.com" and a temporary password. You will need to open the App Store and sign in with these credentials (you can sign out first if needed). This can not be done from a web page, it must be done on an app installed on an Apple device. Once you sign in, you should be provided the opportunity to update your password, and this step is complete.
