Re: [chirp_users] OSX and the TH-D72 with CHIRP

1. Has there been a patch for the TH-D72

Yep.

2. Does this patch include support for the serial device (cu.SLAB_USBtoUART) that is presented to the OS when the TH-D72 is plugged in?

Should, yeah. Just type in the path ("/dev/...") into the serial port box when you go to download from the radio.
