Hi,

As per the HELP document on attaching the profiler, I have added the below VM args to the Java application (launching from Intellij) on Mac OS.

-agentpath:/Applications/YourKit-Java-Profiler-2024.3.app/Contents/Resources/bin/mac/libyjpagent.dylib

The app failed to start with the below error

Please help with this issue.

If you start profiling from IntelliJ IDEA via YourKit plugin, you do not need to modify "-agentpath" : https://www.yourkit.com/docs/java-profi ... p/idea.jsp
