Studio Display Will Not Wake From Sleep

Thanks Grant! Education is always helpful, so understanding the circumstances under which the Mac queries the display

is good knowledge for me. Unfortunately, I still think there’s a bug with the Mac and display detection, as I’ve tried all of those things and they didn’t work, thus requiring the hard boot. When this occurs in the future I’ll continue to try several things before giving up, but as I said, if this occurs during an overnight render and I have to start over that will not be a happy circumstance. I will call Apple support on this at some point and I’ll be sure to come back and post anything helpful here.

• at wake from sleep — so momentarily sleeping and waking your Mac may work

[To wake up any computer I always press the spacebar first, then click the mouse — the other items — disconnecting and reconnecting peripherals comes next…]

• at insertion of the Mac-end of the display-cable, provided everything on that cable is ready-to-go

[I have a dual monitor setup. I tried the main monitor, then the secondary monitor, then both…]

• hold the Option key while you click on the (Detect Display) button that will appear in Displays preferences (from another display)

[Good to know about this option, but as I mentioned, neither display is showing anything when the Mac “fails to wake”.]

Thanks again,

Tom

I have also changed the Prevent automatic sleeping when the display setting and have some new experience. The waking up computer together with Studio Display is more reliable, on the other hand within 5 days I had 3 kernel panic reboots after waking the computer up. What still leads me to suspicion, that in whole this Studio Display topic the issue lays rather on the Mac's side of the cable...

I am having a similar problem however with a different Thunderbolt monitor. My LG 4K on initial boot of the Studio M1 will blink on and off. I too have only found the workaround to be unplugging the Thunderbolt cable.

Note: I am using an OWC Thunderbolt 4 hub - so there's that.

Has this improved for anyone else recently? Without really changing anything (to my knowledge), for the last couple days my computer has been waking as expected when I hit the keyboard or trackpad after it's been asleep. Running macOS Ventura 13.0.1 and whatever the latest Studio Display firmware is.

I wonder if some tiny background update fixed it, like trackpad and keyboard firmware or something like that. At around the same time, the Touch ID button on my Magic Keyboard started to be more reliable as well. It wasn't always giving me the option to unlock the computer with Touch ID on Ventura 13.0.0, but now seems to unlock consistently.

So I had been having this problem since I bought the Studio. I’m running a single Monoprice 49” Ultrawide display and was using a thunderbolt to DisplayPort cable.

But about 3 weeks ago I started using a Thunderbolt to HDMI cable and have not had the waking problem since.

I might switch back to DP to see if it’s the cable or some kind of update in the OS that has made the difference.

But I will say, the day I switched to the TB -> HDMI cable the problem went away and never came back.

There are some days it’s takes a little bit longer (seconds) for the screen to wake and connect, but I’ve never had to pull the cable and reconnect like I had been with the TB -> DP.

I didn't have the issue for a couple of weeks, then it happened again 2 days ago. I spent 5 minutes unplugging and replugging things. I have two monitors, one connected via the HDMI port, and the 2nd with a thunderbolt to DVI adapter. I also have an OWC expansion chassis (with its own separate power connection) connected via thunderbolt, with two additional drives, and I sometimes have other external drives connected via thunderbolt. I prefer not to unplug any of the external drives, because sometimes I have processes running on these (installs, etc.). Two days ago I gave up and unplugged the OWC and an external drive, plus everything else (both monitors, etc.), and the macstudio finally "came back" (began displaying on the main monitor so I could log in).

If the issue gets bad I'll consider changing the "Prevent automatic sleeping when the display setting", but I certainly don't want to do that if it might cause kernel panic reboots (as mentioned by snosek above...)

Our workaround was returning it because COME ON, APPLE!

Waiting 24h for a monitor to boot up is not an option.

A different brand monitor fixed the problem. It's nowhere nearly as nice as the Studio Display, I couldn't buy it at 0% interest with 3% Apple Card rewards, but it has a power button and it starts when we need it.

We got a brand new monitor with the brand new cable that came with it, and bootup would be anything from 5 to 24h. That's right, it would wake up on its own eventually. But we have a schedule and deadlines.

This is an Apple product. It's supposed to work right out of the box. Massive, massive disappointment. How is this being tolerated, I have NO idea.

When the Apple Studio Display, misbehaves, it seems to require a substantial timeout. Disconnect from power and data for a quarter hour. (Sitting facing the corner or sitting on the stairs is optional.)

for my part, I don't want it to turn off at all when I need it... it's annoying when you want to let it download for several hours... It always ends up turning off regardless of the settings.. Never seen that

Been having this same problem with my M1 Max studio, display will just not wake up some times. Unplugging USB-c cable and re-installing always works, sometimes a quick press on the power button does the job. Doesn't happen with my Macbook Pro (Intel processor) so pretty sure this is an M1 problem. Have just learned to live with it for months now. However, a few days ago I purchased a new Apple Magic Keyboard with touch ID and have not had a problem since, as long as I use the keyboard touch-ID. Still a roll of the dice to get the M1 to wake on mouse movement or just a key press. Touch-ID works every time.

Thank you for clarification.

For me:

• Putting the Mac back to sleep and waking it up again does not help
• Reboot yes
• Unplug and plug again the cable into the same thunderbolt port does not help ;-)

I’m having the exact same issue!

I have the same exact issue with my Huawei MateView. I think it’s something that Apple does not want to fix for third-party monitors.

I have no problem with waking my LG 4K (connected to HDMI) and Dell 4K (connected via Thunderbolt>HDMI cable) waking when I wake my Studion Max.
