Hi all,

Many Mac users have stumbled across this annoying error when starting Modelio on their High Sierra:

Or this one while trying to create a project in Modelio:

The most common reason for that error is a too recent version of the JDK.
Modelio requires that a JDK 8 be installed to work properly.
Here's how to proceed to get Modelio to work on your High Sierra:

Step 1 - Download and install JDK 8:

Step 2 - Edit Modelio's 'modelio.ini' file:

First, right-click on modelio3.7.app and run the 'Show package contents' command:

Then, edit 'modelio.ini' with a text editor:

Your 'modelio.ini' file must contain the following items:

-startup
../Eclipse/plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar
--launcher.library
../Eclipse/plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.401.v20161122-1740
-clearPersistedState
-vm 
/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home/bin/java
-vmargs
-Dosgi.requiredJavaVersion=1.8
--add-modules=ALL-SYSTEM
-Xms512m
-Dpython.console.encoding=UTF-8
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts

Note: the /Library/Java/... line has to be adapted to match the JDK installation path of your computer

Go pro
