yes, I discovered today that Apple changed something in 10.11, that works differently than in earlier OS X versions. I have tried to fix it without success. If all fails, bridging the plug-in and the application has to be rewritten using another method, which will take at least a week.
BTW it works the very first time. But when you quit and restart the program, you'll get an error message. So I suspect the VST plug-in would work the first time. But I cannot expect users restarting their Macs all the time. This is very annoying because there were no issues on OS X 10.10.
Thanks,
