Non-notarized plugins not loading

Can't seem to edit my post, but I've found a possible fix for me at least.

Seems like 25.1 would allow loading unsigned plugins, whereas 25.2 needs them to be signed.

Copying the signing step from the Xcode build for the samples has allowed the plugin to load.

codesign --force --sign - --generate-entitlement-der build/install/bin/foo.plugin --deep

Hi @Bruce Bullis

I'm also seeing this, where a development build (built locally on my machine, not signed or notarised) works fine in 25.1 and fails to load in 25.2 on macOS 15.3.2. The same source code works fine on Windows in 25.2.

The structure of the bundle is reasonably simple:

foo.plugin

 \ Contents

    - Info.plist

    \ MacOS

        - foo
    \ Frameworks

        - bar.dylib

Both foo and bar.dylib are fat (arm64 + x86_64).

The plugin loading log shows

"Loading /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/foo.plugin
The registry tells us not to cache so the plugin will be loaded from disk.
Loading from disk...
The library could not be loaded, so the plugin is set to Ignore. The error code: 2685337601"

Sorry, our team has zero experience with build environments, other than the supported, recommended build environment. 🙂

Confirming: The same built (non-notarized) plugin does load in 25.1, but does not load in 25.2? If so, please send me the plugin.

@Bruce Bullis The SDK Sample is imported successfully, so it seems my initial assumption was incorrect about the notarization.

The plugin I'm developing is using a different build system than Xcode.  Would there be another reason why the plugin can load in the prior version and not the current one?

If you build the SDK samples, do they load correctly, on that same system?
