Issues getting Afloat functioning on Mac

[AesisGit]

I have followed the instructions, disabled SIP, restarted etc etc, and on the mySIMBL every time I open it I get a blank white box. I have worked out there is a cancel and an Install but still no option of keeping a window on top. Mainly started looking into this as I was fed up with the RIng App camera hiding whilst trying to work - Ring 2.6.1 (786).

Any help greatly appreciated
