Just obtained new UV-B5. Works OK rf-wise. Installed todays’s daily 20131218 for Mac. Running Mac OS 10.9.1. Python bits are installed and PL2303 driver. Chirp loads and I can select the correct radio and port. When I try the initial download from the new radio I get the Cloning window then "An error has occurred Radio did not ack programming mode.”

Any suggestions, please?
