Osx 15.2

Troubleshooting graphics
1

Hello

since the newest OS update on Macs, Sequoia 15.2), jmonkey applications are not working anymore. The test examples run, but show no graphics (black screen) or a flickering screen.

Any ideas?

Thank you, Michael

Do you recognize any suspicious stacktrace? or any error dialog so far?

I’m running JME apps successfully on macOS Sequoia 15.3 (24D60).
I’ve run them on both Java 1.8 and Java 21.
I’ve run them on both JME 3.7.0-stable and 3.8.0-alpha2.

There are a few gotchas:

  1. To run on macOS, you must pass “-XstartOnFirstThread” to the JVM.
  2. To run on Apple Silicon, you must specify LWJGL v3 (jme3-lwjgl3) instead of LWJGL v2 (jme3-lwjgl) and disable the AWT settings dialog in main() with application.setShowSettings(false).

If you’re still stuck, please provide the Java version and JME version you’re using.

I can make it more precise:
jme 3.7.0-stable
LWJGL 3.3.3+5

The problem occurs ONLY on Sequoia 15.2 and 15.3 on INTEL Macs. It works on all arm and also on Intel-Macs with older OS.

I ran my application with DEBUG mode. It opens the Window, but does no rendering. In the working situation, the logfile log the compilation of the shaders, which is in the problematic sitauion not the case. We don’t get any exception.

A friend haveing a OS-X 15.3 machin reports, that alos the test cases do not run.

Here is the log:

Thanks for the additional details.

My best guess is it’s an LWJGL-on-MacOS issue. Alas, I currently don’t have access to any Intel Macs where I can run interactive tests. I’ll do some searching and think about what tests you might run to further pin down the issue.

Can anyone else assist with troubleshooting?

  • First thing i would do is to check if lwjgl2 works. As far i know intel mac’s should still run that?
  • Enabling graphics debug if not yet done:
settings.setGraphicsDebug(true);

  • Osx should be able to run a 4.1 core profile

  • test with a never version of glfw might be an option too

Meta forked renderdoc and offers an macos version, not sure however if it supports only meta devices

This line bothers me a bit. I think LWJGL implements a retry here, but why it fails in the first place? Could be loading wrong binaries afterwards?

The reason for this (library opening) is, that I deploy the native libs not inside the jar but as extra file on the lib path. This is ok.
To give another hint:
On the Old intel macs with the new sequoia, the program runs with
Jme 3.2-stable and LWJGL 2.9.3
But not with jme 3.3.2 and LWJGL 3.3.0 and alos not with the newer ones
From my point of view, the Window-System changed to GLFW. Maybe this is the reason?
