[Regarding macOS Tahoe](Updated October 16, 2025)
macOS v26 Tahoe is now supported!
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.

Thank you for providing the data.
This matter is currently being investigated by our development team.
Please wait for a while.
Thank you for your cooperation.
Thank you for your patience with our response.
I would like to check something.
Does the problem occur after reinstalling Cubism Editor 5.0.06?
Do you have problems with Cubism Editor 4.2.04 or 5.1.00?
Are you using any resident software or security software that manages windows? If so, close them completely and try again.
Does the problem still occur when you double-click on CubismEditor5_d3d.bat to start the program?
If you have checked these and still have problems, please open CubismEditor5.bat from the command prompt as shown in the image and send us a log until it crashes.
Best regards.
