The old code didn't work on El Capitan -- there were some visual artifacts left behind afterwards.
Since I didn't have access to a machine running El Capitan, I replaced the code with something that work on all OS versions.
It might be possible to increase the size -- however, the symbol is a built-in image so there is a risk that an enlarged version will be pixelated.
I'm open to other solutions to this. Unfortunately, I don't have the time to work on it myself anymore.
