Hi everyone,

I have a Photoshop UXP plugin. The plugin works perfectly on Windows, and I tested it on two different Windows computers.

I don’t own a Mac, so I hired someone to help prepare a macOS version. I enrolled in Apple’s Developer Program and paid for the membership. Using GitHub Actions on a macOS runner, I built the macOS native components, signed and notarized them with my Apple Developer ID, and packaged the plugin as a `.ccx` file. The GitHub Actions workflow completed successfully and produced the artifact `Recky-1.3.60-Mac-Signed-CCX`.

I downloaded the artifact and sent it to someone with a Mac to test. They tried these steps:

1. They extracted the `.ccx` from the downloaded ZIP and double-clicked it. Creative Cloud showed **“Not compatible”** and installation failed with **error code -6**.
2. They renamed the `.ccx` file to `.zip`, extracted its contents, and placed the extracted plugin files in the UXP `Plugins/`folder ( insde the plugins folder they created a folder with the name of the plugin, then inside of it put all the files ). The plugin did not appear in Photoshop’s **Plugins** menu.
3. They now tried to also placed the original `.ccx` file in that folder and double-clicked it, but got the same **error -6**.

The Mac was reportedly running Photoshop **27.10 or 11**

Could the error be caused by the plugin’s `manifest.json` compatibility settings, the `.ccx` package structure, or the native macOS architectures? What should I check first? Is there a recommended way to validate a privately distributed hybrid `.ccx` before testing it on a Mac?

I can privately provide the manifest, workflow details, screenshots, or logs. Please help
