Mac OS X Specific Notes

Under macOS 11.6.3 (Big Sur), the contents of the windows might be blurry.

The fix is to edit $PTII/bin/Vergil.app/Contents/Info.plist and change 
      <key>VMOptions</key>
      <string>-Xmx4096m</string>
to 
      <key>VMOptions</key>
      <array>
        <string>-Xmx4096m</string>
        <string>-Dsun.java2d.uiScale=2.5</string>
      </array>
See #342 Blurry Fonts on Mac.

You are running a 1.6.0_65 version of the Java Platform

If you click on the installer and get a message that says 
      The application that you are trying to install requires a 1.8 version or later of the Java platform. You are
      running a 1.6.0_65 version of the Java platform.  Please upgrade to a new version.

that looks like:

Java upgrade needed

then the problem is that you don't have a Java 1.8 JDK or JRE installed. See below for information about which Java to install.

If you do have Java 1.8 installed, then the problem could be that Java 1.6 was previously installed. See Mac: app requires Java 1.8, which is not found even though it is installed.

The workaround is to execute the installer by hand:

bash-3.2$ cd ~/Downloads/capecode0.1.devel.setup.mac.app/Contents/Resources/Java
bash-3.2$ ls
capecode0.1.devel.setup.mac.jar
bash-3.2$ java -version
java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)
bash-3.2$ java -jar capecode0.1.devel.setup.mac.jar 
Command line arguments: 
...

Java

Ptolemy II requires Java, which may be downloaded from Oracle. We suggest installing the JDK, see http://www.oracle.com/technetwork/java/javase/downloads/index.html. 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.

The installer requires that a Java 1.8 Java Runtime Environment (JRE) be installed.

Documentation

Environment Variables and macOS

Note that some demos, such as the hlacerti demos, require certain environment variables to be set. If, under Mac OS, Vergil is invoked by clicking on Vergil.app, then these environment variables will not be set. The workaround is to invoke Vergil using $PTII/bin/vergil. See #329: Under macOS, Vergil.app does not set environment variables needed for hlacerti demos.
