iMac Pro ignoring Energy Saver settings
Hi all
I have an iMac Pro (3ghz, 32gb ram, 2tb ssd, Vega 64) and it's been misbehaving lately with regards to energy settings.
I have it attached to a G-Tech G Speed Shuttle via TB3 (and two other drives via USB in case that is relevant) and the Shuttle has an irritating feature that can't be turned off, where it beeps twice whenever the system it is attached to wakes from sleep, and orders the Shuttle to spin up.
This was causing the Shuttle to beep every 20-30 minutes, all night long while my iMac was supposed to be asleep.
At first I just turned off Power Nap and it worked, but then that suddenly stopped working after a couple of weeks and the nighttime beeps have started again.
I've also turned off Wake for network access and Put hard disks to sleep when possible, and still no luck. The beeps start very soon after the computer goes to sleep.
