Ptolemy II 10.0.1 Notes for Mac OS X


Mac OS X Specific Notes

Help! I clicked on the Mac Setup file and got a strange dialog

If you get a dialog like:

setup is damaged and can't be opened. You should eject the disk image.

Then the problem is that your version of Mac OS X has a bug and needs to be reconfigured.

The bug is that the dialog should state that the dmg file is unsigned and ask you if you would like to change your settings. The file is not damaged. The bug is that the Mac operating system is incorrectly labeling the dmg as damaged because of settings in the Gatekeeper control panel.

OS X: About Gatekeeper describes how to fix Gatekeeper to allow applications downloaded from anywhere.


Ptolemy II requires Java, which may be downloaded from Oracle. We suggest installing the JDK, see Note that recent versions of Mac OS X may prompt you to install the JDK if it is not yet installed.

The Ptolemy installer for Mac will install a version of Ptolemy with a JRE that includes:

  • Java 3D, which is required to run the Graphical (GR) domain demos.
  • The Java Advanced Imaging Interface.
  • The Java Serial port communication interface.
  • The Java Media Framework.
