Some successes, but still some issues:
Bluetooth works, which it didn't before.
No Audio through speakers, which I did have working.
Bluetooth audio to my Bose portable speakers only works if I select the BT speaker as both input and output and is poor quality. This only works if I have the System Preferences -> Sound -> Input pane open.
Audio Fn keys seem to work ok
I now have a Backlight slider under preferences which works. Auto-Brightness doesn't work, but maybe that's because there is no light sensor. Brightness adjustment keys (fn-F2,fn-F3) do not work.

Both USB 3.0 ports work. I don't know if USB-c works, as I have nothing to test it with.
Keyboard backlight key works, but auto control does not. I don't care.
It's better than it was. What next?
