[chirp_users] BF-888 Mac problems
Use a Mac to program BF-888 and UV-82 radios. All works well in downloading and uploading programming to radios, however after programming the BF-888 and I shutdown CHIRP my Mac becomes unresponsive to keyboard input. Computer will not shutdown or restart. I have to do a hard shutdown on the computer to reset everything. When I program the UV-82 the computer behaves itself when I close CHIRP and I encounter no problems.

Ken,
I don't have a BF-888S, but I started looking at the driver a couple of days ago based on some issues reported to me by my friend John (he has one). The one thing that I noticed yesterday was the h777.py driver reads the settings from the image files that I have, but it for some reason does not save the changes back to the image file.
I mentioned this to John and he reported back this morning that the changes made in CHIRP don't get written to the radio either. He mentioned that the progress bar goes to about 25% then skips to 80% and then continues to the end. I'm not sure what the problem is, but something is certainly amiss.
I would suggest that you open an issue. Include an image file and a debug.log file if you can.

I would check and replace the device driver for your USB serial cable.
Have you tried disconnecting the cable while your Mac is hung to see if it recovers? Also if you have another machine, see if your Mac is still pingable while it is in that hung state.
An application should not be able to cause the operating systme to hang or crash.
Device drivers run inside the operating system kernel and have direct access to the hardware and can cause crashes and hangs.
(note: The radio specific code in CHiRP is referred to as a driver as well but it's not a operating system *device* driver, it's part of an application.)
There may be something about the chirp code for the 777/888 that triggers a latent bug in the USB device driver, possibly some edge condition which is why you don't see it with the UV-82. The 777/888 code might need to be fixed but it shouldn't be able to cause the Mac to hang.
Hope this helps, --Rob
