I’ve gotten a lot of reports from mac users that the URL scheme handler doesnt seem to be working right when triggered from my Fantasy Grounds extension. A quick browse of the thread here and you can see several posts. https://www.fantasygrounds.com/forums/showthread.php?53459-MK-Syrinscape-Sound-Links-module
One community member went so far as to write a small utility application to pick it up and send the request to the REST API. His utility can be found here https://github.com/Moroverse/syrinscape_bridge/releases
I thought I’d report it for you to take a look at and see what, if anything might fix the issue the Mac users are seeing.
This only happens when using the native Mac Syrinscape Online app and Native Mac Fantasy Grounds Unity
