+**NB**: As of 10.10, OSX now bans drivers that haven't received explicit approval from Apple. The only workaround I'm aware of is to set a system flag to [globally allow **all** unsigned kernel extensions](http://apple.stackexchange.com/questions/163059/how-can-i-disable-kext-signing-in-mac-os-x-10-10-yosemite). This means WavTap *will not work* unless you've enabled `kext-dev-mode`, using something like this:
+
+```shell
+sudo nvram boot-args=kext-dev-mode=1
+```
