Re: [chirp_users] CHIRP support for MacOS/Prolific

One thing you can try is to go to Apple Menu > About this Mac > System Report

From there, scroll down the left side and click USB. Plug in your cable,

hit Command-R to refresh. See if a new device appears, remove the cable, refresh again, see if it goes away. If you can see the cable appear and disappear then you've got drivers for it already working. MacOS does have some drivers built-in.
