MP 1,1-5,1 MacPro 5,1 Wont turn off

[deckard666]

My cMP 2012 running High Sierra has literally been on 24/7 for the last 2 years for Plex and torrents but with the price of electricity I have started switching it off at night ..the trouble is it wont power down fully...when I have clicked shutdown it never does, the white light on the front indicating power never goes off unless I force it to by holding it down. Any ideas ?

Check the RTC battery voltage with a voltmeter/multimeter, replace the BR2032 battery for another one of the same specification if the voltage is below 3.00V.

Screen turned black, but the power light still on? How long you wait? 5min? 20min?

Did you checked the RTC battery voltage? Besides the very known sleep problems and overall crazyness when the RTC counters became stuck, it's common that you can't shut down the Mac Pro when the battery voltage is too low.

Can you shutdown the mac by using this terminal command?

sudo shutdown -h now

Good idea - got this

“shutdown: / is busy updating; waiting for lock”

Did a quick google and found this -

“Fixed it. I ran the shutdown command then started killing likely suspects in in activity manager. Turns out kextd was the culprit. I thought. would have to go back after restart and kill it every time I wanted to restart until I found the offending kext but after that initial quit command everything is functioning as it should.”

So I tried killing that in activity monitor and it’s just shut down !

We will have to see what happens when I boot it up tomorrow and see if it shuts down smoothly from the shutdown menu
