Gradebook is an app that is not registered with Apple as an identified developer, so when Powerschool is updated, it does not break Gradebook, you just have to allow it to run again on your MacBook. To override your default security settings and open the app, do the following:
- In the Finder, locate the app you want to open.
Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
Press the Control key, then click the app icon.
Choose Open from the shortcut menu.
- Click Open.
When you try the old launch and click on the .jnlp file , press control and click the app and let it give you the message that it is from an unknown source - then open up security in system preferences and it will ask you if you want to make an exception to the setting for that specific application. Click allow, close prefs, then try to open app again and it should run.
If you still have problems, you may do the following:
Open System Preferences and go to the settings in Security & Privacy preferences so you may specify the sources of software that run on your Mac.
|Mac App Store:||Allows apps only from the Mac App Store. All the developers of apps in the Mac App Store are identified by Apple, and each app is reviewed before it’s accepted. OS X checks the app before it opens the first time to be certain it hasn’t been modified since the developer shipped it. If there’s ever a problem with an app, Apple removes it from the Mac App Store.|
|Identified Developers:||Allows apps from the Mac App Store and apps from identified developers. Although apps from outside the Mac App Store are not reviewed, the identified developers are registered with Apple. If problems occur with an app, Apple can revoke its authorization. OS X checks the app before it opens the first time to be certain it hasn’t been modified since the developer shipped it.|
|Anywhere:||Allows all apps from anywhere. This setting turns Gatekeeper off. However, this is the least secure setting because the source of the app is not verified, and the app is not checked to see if it’s been modified or is broken.|
To get Gradebook to run, you need to select ANYWHERE.
