MPS requires a Java Runtime Environment in version 11 oder higher.
MPS runs out of the box with all Java versions starting from Java 11 up to Java 15 (inclusive). In order to run on Java 16, additional configuration might be required. Refer to the Java 16 section below for more details.
MPS is available as standalone application or as an addition to an already installed Eclipse application on your system.

Running MPS on Mac OS X
Important note for Mac OS X users: In recent versions of OS X, the application can not be opened directly and an error message saying that the application is “damaged” is displayed. The reason for the error message is that the application is not signed by a Apple-verified developer. In this case, open a terminal and enter the following command:
sudo xattr -rd com.apple.quarantine /Applications/MPS.app
This assumes that you have installed
MPS.app in your default Applications folder. In case you have it installed elsewhere, you have to adjust the path (for example
~/Downloads/MPS.app if MPS is still in your Downloads folder).
The administrator password has to entered to unlock this action (typed characters are not displayed for security reasons).
In previous versions of Mac OS X (10.14 Mojave and below), the problem can be solved by disabling Gatekeeper temporarily with the following command:
sudo spctl --master-disable
If MPS still won’t start, go to System Settings -> Security -> General and unlock MPS.app in the lower section. Afterwards, start MPS.app and activate Gatekeeper again with the command
sudo spctl --master-enable
Running MPS with Java 16+
When processing MusicXML files with MPS and Java 16+, the MusicXML parser runs into an
java.lang.ExceptionInInitializerError caused by a
java.lang.reflect.InaccessibleObjectException. This can be solved by adding the following line after
