Not sure what you are doing wrong then.
Also the Mac wallet doesn't open upon launch, it just crashes (OS X 10.12.6)
Send me crash log, please.
I haven't tested it myself, but it's more than likely the OSX version was linked against stdlibc which doesn't exist in 10.12 or that the libraries it was built against aren't in the rpath for the qt application.
It probably needs to be built against 10.7 target on 10.11 SDK, linked to stdlibc and all the those included in the rpath in order for an OSX wallet.
