Managed Software Center is your "local" App Store for UiO work software . It is, like the Apple App Store, an application on your Mac, where you click to install software that is prepared and approved for use at UiO.
PS: Some software may require additional licensing offered by some faculties, for some users, like for instance the Adobe suite.
How to use MSC

in your Dock. If it's not there, it?s located in the "Applications" folder (shift+cmd+a). Drag and drop to the Dock.

? Search or browse for the software you want to install, then click Install.
If you have the application installed, you will see that the button reads "Remove" instead. Clicking this will uninstall the software.
? If there are available updates to any of the applications installed by MSC, there will be a numberbadge on the Dock Icon, and a number on the "Updates" tab. Click the update tab, then choose which apps to update, then the blue update button.
