[Regarding macOS Tahoe](Updated October 16, 2025)

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.
