[Regarding macOS Tahoe](Updated September 18, 2025)
We cannot guarantee the compatibility of the current releases of Live2D Cubism Editor and Cubism SDK with macOS Tahoe.
We advise against upgrading your macOS at this time as it may cause Live2D products not to function correctly.
Upgrading macOS can also cause you to lose your Cubism Editor license file.
Please make sure to deactivate your Cubism Editor license before upgrading the macOS.

Live2D Cubism Viewer Crashes before .moc3 File Can Be Loaded
The software itself opens without a problem, but when a .moc3 file is loaded into the viewer, a small text box briefly appears containing the text "Setup Viewer..." before crashing. A crash log is generated within the Live2D program folder, which I can provide upon request.
My graphics processing driver is updated to the latest version, I have installed Adobe AIR, I am not sure why this is still happening. Any help is greatly appreciated
Thank you
