Cross-platform ZXP Signing Compatibility Known Issue and Workaround 2024
The problem: ZXP files signed on macOS are failing when installed and run on Windows machines, and vice versa. On Windows, this may mean that the installed panel appears blank, or only functions as expected with debug mode enabled.
Expected Behavior: Historically ZXP files signed by ZXPSignCmd may be installed and used succesfully on both macOS and Windows, regardless of which platform they were signed on.
The Workaround
For the time being, the work around is to sign ZXPs on the platform they are expected to be run on. Sign ZXPs for use with macOS on a macOS machine, and ZXPs intended for Windows on Windows devices.
