RehabMan,
I have done 10.12 Sierra install, it smoother than I expected!!
BTW I still have encounter below problem:
1) Harddisk and Wifi indicator still "on" or it still amber led on. The indicator have 2 color, amber and white: wifi amber may mean not connected to wifi network ( I saw it was always amber anyway), and harddisk: amber may mean shock protection and white mean read / wirte.
after I Power off my notebook. I found that they always on even I unplug and plug back the battery. However, it won't happen after I shutdown by Windows
- tried EC reset, wifi led was off after plug in battery, but hdd led still on. After plug in power support, the wifi indicator was on.
Shutdown again were the same - both wifi and hdd LED in amber)
I can see the shutdown message in verbose mode:
after CPU halted:
CPU halted
AirPort: Link down on awdl0. Reason 1 (Unspecified).
AGPI (not sure the first character): 391.061420:Airport_Brcm43xx:: syncPowerState: WWENI(disabled)
I am using BCM9435z card.
2) wifi button: after press, it will disable Bluetooth and Wifi. Press one more will only enable Bluetooth, Wifi cannot enable until reboot (no need go into Windows again)
thank you very much!
