I also downloaded for mac. Hooked up the cable to my baofeng uv5r which immediately went into transmit mode. Very weird

Usually caused by one or both of the following:
- the plug of the programming cable is not fully inserted into the socket. There can be many causes for this but with these UV-5R like radio models with the recessed speaker/mic socket, the plastic plug shell can contact the radio case causing interference that won't allow the plug to be fully inserted. This is especially troublesome with the GT-3R style cases.
- a compatible device driver is not present or there is a problem with the USB connection. This is really common with programming cables manufactured with Prolific type chips. The chip vendor end-of-lifed their PL2303HX chip (common in most programming cables) over a decade ago and removed support for it from their driver causing issues like this. Recently (towards the end of last year) they did the same thing for their PL2303TA chip. Also when there is no driver installed (as in the case when the USB end is not plugged in, the computer is powered off or rebooting), the radio can be forced into transmit mode by the programming cable. This is why I cringe when I see someone recommend programming their radio with the antenna removed!
This is not a problem caused by CHIRP and there is nothing that CHIRP can do to resolve it.
