Close your modeling tool, delete all cache folders and start the program again.
Cache folders can be found in <user home directory>\.<modeling tool>\<version number>, for example <userhome>\.magicdraw\<18.2>.

If the problem still exists, please add the -Dcom.sun.media.imageio.disableCodecLib=true option into the JAVA_ARGS line in the modeling tool properties file, for example magicdraw.properties. A properties file is in <modeling tool installation directory>\bin.

See the example:

JAVA_ARGS=-Xmx4000M -XX\:PermSize\=60M -XX\:MaxPermSize\=200M -DLOCALCONFIG\=true -splash\:data/splash.png -Dmd.class.path\=$java.class.path -Dcom.nomagic.osgi.config.dir\=configuration -Desi.system.config\=data/application.conf -Dlogback.configurationFile\=data/logback.xml -Xss1024K -Dcom.sun.media.imageio.disableCodecLib=true

To initialize log4j, open <MagicDraw installation directory>/data, and modify the debug.properties file.

Change the debug level for appropriate categories by specifying log4j.category.<category>=DEBUG or turn on debug for all categories log4j.rootCategory=DEBUG,SO.

Please restart your computer. After multiple updates or after installing different versions of a modeling tool on the same machine with Mac OS, sometimes it happens for unknown reason.

In most cases such error appears when installer file is truncated or corrupted.

Please try to download an installer again.

Another option is that /usr/bin/java is an old version java. To check which java is used by installer, set environment variable LAX_DEBUG and launch installation again.

By default installer first uses java found in /usr/bin. But there is possibility to use specific VM when launching the installer. Please add parameter LAX_VM to launcher and second parameter path to java executable, here is an example (assuming that java is in /opt/j2sdk1.5.0_03):

./MD_UML_105_unix.sh LAX_VM /opt/j2sdk1.5.0_03/bin/java
