MP 7,1 Unable to Get Late 2019 Mac Pro To Sleep

I purchased a Late 2019 Mac Pro (12 core, 192 Gb of ram, AMD Radeon Pro Vega II 32 GB) in December, and it has been working perfectly with no changes in the peripherals connected since it arrived. About 3-4 days ago I found that the Mac Pro would not go to sleep when Apple>Sleep is selected. The cursor disappears and my Pro XDR display turns off as it should, but the Pegasus2 R6 and other hard drives that I have attached do not go to sleep as they have always done in the past.

Here are the steps that I have taken to try and solve the problem.

(1) I checked System Preferences>Energy Saver to make sure nothing was checked.

(2) All peripherals except the display and Ethernet were disconnected from the Mac Pro and the System Management Controller (SMC) reset by unplugging power for 5 minutes and then restarting.

(3) With all peripherals disconnected I started the Mac and immediately pressed command+option+p+r and held until the login screen appears to reset the NVRAM.

(4) With all peripherals disconnected I booted while holding the shift key to boot into safe mode.

(5) I set up a Guest User account and logged into it after booting the Mac Pro.

(6) I reinstalled the Mac OS by booting with Command R and installing the OS.

After trying each of the above, I attempted to get my Mac Pro to sleep, but it persists in not doing so. Frankly, I am out of ideas and have no idea why this Mac Pro which had been sleeping every time I selected Apple>Sleep suddenly now refuses to go to sleep.

I would appreciate any suggestions that you may have since all I can do now is to shut down my Mac Pro anytime I am not using it. Thank you for reading this and thank you in advance for responding.

Well you could try this in Terminal to find the culprit: pmset -g assertions
Explanation: https://www.macworld.com/article/1168151/find-out-whats-keeping-your-mac-awake.html

There's also a column in Activity Monitor/Energy tab that displays if a program prevents sleep.
Thank you very much for responding. I had already checked Activity Monitor for programs preventing sleep but there were none. I will definitely check out the terminal command and the link you so kindly provided to me. Again, thank you and I’ll respond when I have had a chance to follow up.

Here is what I got after invoking the terminal command. Please let me know if you see anything that you think might could be causing my Mac Pro to fail to go to sleep. I did not see anything unexpected, but I am in over my head with this issue and I thank you for your help.

There are no programs at all (i.e. blank screen) when you go to Activity Monitor/Energy... correct?

When I go to Activity Monitor/Energy I see all of my programs but each one of the programs says "No" in the column labeled Preventing Sleep.

Is this true for Finder and for Mail? They can be sneaky :cool:

Finder has a "No" in the Preventing Sleep column. Mail is greyed out and has a "-" in the Preventing Sleep Column. Other programs that are greyed out with a "-" in this column are Final Cut Pro X, Malwarebytes Protection, MInstaller Progress, System Preferences, and Terminal.

pid 549(sharingd): [0x000000ee00018305] 00:00:45 PreventUserIdleSystemSleep named: "Handoff"

This looks like the culprit. Try disabling Handoff or look for a setting to not have it wake the machine and then sleep the computer.

I went into Activity Monitor and tried to quit Shardingd (handoff). It appeared to start right back up. I then selected Sharing and did a force quit, but again it seemed to start back up. I tried sleeping the Mac Pro. It would not go to sleep. I then went into Apple>System Preferences? General and unchecked the box for Allow Handoff between this Mac and iCloud devices. I rebooted. I waited 2-3 minutes for the Mac Pro to full boot and I attempted to get the Mac Pro to go to sleep. As usual the screen immediately goes dark, but all of my external drives remain awake. I can tell from the blue activity lights on my Pegasus2 system that when I tell the Mac Pro to go to sleep, the Pegasus2 appears to get no signal from the Mac Pro (i.e. the blue activity lights on the Pegaus do not flash even once).

I confess I have no experience with this Pegasus device but a quick google led me here:

Does the computer sleep when you use it without that?

I, too, believe that somehow the Pegasus 2 is responsible for my sudden failure of the Mac Pro to sleep, and I thank you for this link. It shows that recently others with Pegasus raid systems attached to their Macs are having this problem, and no one found a solution other than to say the MacOS is at fault. However, even with the Pegasus drives disconnected from my Mac Pro it still seemed not to go to sleep. Let me recheck that and get back to you. Thank you so much for all your effort to assist me in resolving this issue.

The problem is definitely that the Mac Pro unable to put the Pegasus2 raid arrays to sleep. With the Pegasus2's attached the Mac Pro will not sleep. With the Pegasus2 removed from the system, the Mac Pro goes to sleep perfectly as confirmed by the slow flashing activity light on the MyBook external drive and the blue light going out on the Samsung Portable SSD. I would have seen immediately that the issue was the Pegasus2 if Apple had not changed the LCD on the Mac Pro from blinking slowly when it was asleep to burning continuously whether it was asleep or not. The activity lights on the MyBook and Samsung SSD are so faint that I did not notice they had gone to sleep when I originally disconnected everything from my Mac Pro.

Once again, thank you for working with me to at least understand this issue. I am now lodging a support ticket with Promise Technology (who make the Peasus systems) although I have found their tech support to be nearly totally useless.
