Just wanted to give the powers that be a heads up on this.

If you open the addon on mac and have macros created using the cmd key, the addon incorrectly identifies them as being problematic.

for example I get

Invalid argument: mod - shiftctrlcmd

or

invalid argument: mod - cmd

when the macros work fine. I assume this is due to the omission of cmd being viable on mac (as opposed to alt on windows)
