New Mac Studio M1 Max won't go to sleep

[boynigel]

the first week I had it, I'd select Sleep from the apple menu. the screen would go dark, making me think the task was done, but then two seconds later it would come back on. The second attempt was always the charm for about a week... until last night. I selected Sleep roughly 5 times in a row, and it would wake up 3 seconds later every single time. the only fix was to go into System Preferences and set the timer to put it to sleep after 3 minutes...which isn't my preferred method.

So it will go to sleep, just not manually. I'm running 12.3.1. There are worse problems to have, but I'm wondering if anyone has a fix for this.

I stopped trying to get mine to go to sleep; it was never clear when/if it actually went to sleep and when/if it came out of sleep when I wasn't using it. So I just let it be on.

I have used SleepAid from Ohanaware to try to diagnose, but there seem to be a lot of issues.
My biggest issue is activities on the USB bus. Mine has a lot of devices hanging off that.
Since power consumption is extremely low and the screen does turn off, I have not spent much time on it.

 

[boynigel]

you make a good point of not knowing for sure if it was asleep or not. I thought about that too because every Mac I ever had would do this thing, while asleep, with the power light, where it would cycle going from dim to bright...almost like it was breathing (snoring?)

My Mac Studio does not do this. The light stays bright at all times, as if it is on. So either Apple got rid of the brighten/dim thing, or it's not going to sleep as we're suspicious of.

I think tech savvy folks still maintain it's better to not shut it down every time you're done using it, but rather just put it to sleep. I've not problem w/that if it's actually sleeping, but I don't feel good about it being on 24/7. that can't be without its consequences either in the long haul...but what do I know?

@haralds
I too have a lot of USB (A) hooked up, including an older 4-port USB hub, BUT...everything that's connected to it is off, although the hub itself does stay on. Perhaps I'll try disconnecting it next time I put it to sleep and see if that changes anything.

Same issue here, if you find a solution please let us know.

I never set my desktops to sleep. I have the monitors turn off after 30 minutes but the processor draws very little power and it prevents a lot of issues with attached devices. I have my wife's and my M1 iMacs running with both displays on and the UPS shows 50 VA power draw.

The same occurred out of nowhere on both M1 Mini 16 GB (with prior macOS versions + latest) and Studio Base Max for me.

My "remedy" was to disable Bluetooth and use a wired keyboard and mouse. Sleep comes "naturally" now. (with one click/keyboard shortcut combination) ~99% of the time.

In my old Mac Pro with 2 generation ago OS there was the option to disable the mouse from waking up the system but I can't find that option in Monterey and I really like the Magic Mouse.

Magic ones are nice though, I'm quite at home with the old tiny ball in the middle A1152 USB mouse at this point.

Other than power draw, what is the problem with running it 24/7? You worried about the fan motor wearing out? I think that is the only moving part in the whole thing.

Just wondering, cause I don't think I ever put my computers to sleep. Monitor off yes, but the computer stays on, along with all connected devices.

 

[drewaz]

probably a silly question but ... if the monitor is off how do you know if the computer is asleep?

Maybe lack of fan noise? I know the power light stays on solidly.

Mine is totally silent .... I click SLEEP from the Apple menu ... the monitor turns off but I'm never sure if the computer stays asleep ....

Ping the IP address of your system from another device and see if it replies...

I shut down my Studio Max every night.
Back in the bad old HDD days when it took my computer two minutes to boot to a working and 'settled' desktop, I used to leave it on overnight with the screen off, because two minutes felt like an age. But now I can't see the point. I've owned my Studio nearly three months and I've still never seen the boot screen yet, because by the time my monitor has sensed that the Mac is switched on and wakes from sleep, the Mac is already at the login screen. It's that quick.
No matter how little electricity the Studio Max is using while sleeping, it's still more than when it's off.

One of the reasons I don't shut down my Max: it's positioned at the back of my desk and it's difficult to find the power button without moving the computer.

how do I ping the IP address?

 

[now i see it]

Betcha it’s a mouse issue

Ah ok. It's a bummer that the power switch is on the back. I wanted to hide my Studio away completely, and have the thing automatically boot up when it receives mains power (which I would have achieved by putting it on a remote controlled switch, same as the rest of my home studio equipment). But Apple have never built that into a Mac's functionality. PCs have been able to do it for decades. It's one of the few aspects of Macs that's really lame.

Dust id the fan spins and also the power may be relevant if like me you have 8 HDD attached. Also the longevity of mechanical HDD. With my old Mac the external box was going to sleep as well.

I just did a small experiment. My Studio is silent but I listened to it with a stethoscope and could hear the fans ... used the Apple icon and chose sleep ... the display went off but I could still hear the fan. When I shut it down the fans were silent. Also pinged the Studio and it responded.

so .... it hasn't been going to sleep. the only reason I care is that I don't want the fans running constantly and sucking in dust. I'm sure there is something connected that's responsible but rather than look I think I'll just shut it down over night.

There was a post in another thread about this recently. If you want your Mac Studio to go to sleep and stay asleep (no response to any network requests or pings, no activity at all while sleeping, and so it will only wake if you manually wake it up yourself via physical access to the machine) then you can run these commands in Terminal:

sudo pmset -a tcpkeepalive 0
sudo pmset -a powernap 0

If you change your mind, run them again but changing the 0 to 1.

Thanks, I will try the power nap. My system indeed goes to sleep but wakes up very often for 1 or 2 minutes than it sleeps again. Unfortunately once in a while it wakes up and stays up. I disabled the ethernet wake up from the settings so I will try the power nap first.

You're welcome. Note that the "Wake for network access" setting in Energy Saver is controlled by a different Terminal command, sudo pmset -a womp [0 or 1]. Somewhat confusingly, even when this setting is off/set to 0, it does still allow some network activity while the computer is asleep.

The sudo pmset -a tcpkeepalive 0 Terminal command I mentioned earlier is a much more restrictive command that does not have a corresponding checkbox in Energy Saver. It stops any and all network activity while the computer is asleep. It is the brute force option to ensure that the computer will not wake from sleep until you physically wake it up.
