Hi Paul,

thanks for the report. At least good to know, that I'm eventually not doing anything wrong, though I hoped for a switch I just forgot ;-)

> Let me know if you stumble across a fix.

I will do, please do so as well :-)

Cheers,
Daniel

Daniel -

We're seeing this exact issue with a bunch of our plugins. Worked fine in El Capitan, and randomly doesn't work in Sierra, usually on machines that were upgraded. Clean installs usually fix it. We've been waiting on input from the launch services folks for months.

Let me know if you stumble across a fix.

Hi Darrin,

thanks for the answer. I tried that, removed all symlinks I created of
either FxPlug folder in /Library and in ~/Library.
I also started the Wrapper Application from Finder and let it run for a
couple of seconds.

But neither pluginkit -m shows anything, nor it is visible in motion.

I also tried to reduce deployment target to 10.11 (but I am on 10.12
though). No change.

Can I look into launchServices database? Is it worth resetting it's
cache? Exists there any logging from that service?

Thanks for walking me through.

Daniel

    Daniel,

    You don’t need to do the linking to /Library/Plug-Ins/FxPlug/ since
    you’re working with PluginKit. I’d remove the link just to make sure
    it’s not causing any other issues.

    Next, I would find your plug-in’s application in the Finder and
    double-click on it from the Finder to launch it. We have seen cases
    where Launch Services doesn’t notice the plug-in the first time it’s
    launched from Xcode. As such, it doesn’t register with PluginKit.
    Launching it by hand from the Finder seems to nudge Launch Services
    to where it recognizes the plug-in. Let me know if that works for you.

    Hi everybody,

    I try to create a generative plugin with FxPlugin. I am using
    FxPlug SDK 3.1.1 on OSX 10.12.4

    First I create an empty FxPlug project with XCode (8.3.2). Then I
    change the base class to
    @interface FilmstroFxPlugPlugIn : NSObject <FxGenerator>

    and adapt the frameSetup removing RenderInfo, that the FxGenerator
    doesn't have:
    - (BOOL)frameSetup:(FxRenderInfo)renderInfo
              hardware:(BOOL *)canRenderHardware
              software:(BOOL *)canRenderSoftware

    and also the renderOutput removing the inputImage:
    - (BOOL)renderOutput:(FxImage *)outputImage
                withInfo:(FxRenderInfo)renderInfo

    For a start I commented everything out and return YES.

    The project builds fine, no warnings (except the documentation
    inside the SDK).

    Then I link from products the .fxplug into /Library/Plug-Ins/FxPlug/

    But pluginkit doesn't show the plugin. pluginkit -a finishes
    without a message. But still pluginkit -m doesn't list the plugin.

    I can run the Application as well, but it shows only an empty
    window, as I didn't implement anything there.

    How can I troubleshoot, why it is not showing up?

    N.B. I had a version showing up, but then I realised, that my
    changes didn't have any effect, so I removed all traces by hand.
    Now I tried to start over, but now I don't even see an empty plugin.
    I used XCodes "New FxPlug project", so the GUIDs should be unique.

    Thanks for help,
    Daniel
