I am having issues with my mac restarting every time I go from the couch to plugging it into my OWC thunderbolt dock and sometimes just a regular charger. Anyone know about this? The other day my computer went into safe mode when i went to use it because it kept timing out while in sleep.

i use the original apple thunderbolt 3 cable from the dock to the computer. Only other thing connected is a monitor.

Sleep transition timed out after 35 seconds while calling power state change callbacks. Suspected bundle: com.apple.driver.AppleThunderboltNHI

I just got this twice today for the first time since I bought the M1 MacBook Air on launch day, Nov 17th. I'm using a Caldigit SOHO USB-C dock but I have been for at least a month without this kernel panic. It is weird to get it twice in one day but never before. No idea what caused it but I reported it to Apple.

Mine is not exactly the same, I get Wake transition.. instead of Sleep transition.

My M1 mini started doing this on 11.3 beta 5 and continues in 6. I have a USB card reader and USB C hub with a monitor and 2 drives attached and thats all. Some people say it's caused by USB devices not responding causing the sleep transition to timeout.

So I last posted on this on Feb 20 and I haven't ever seen it again. Weird stuff.

My M1 MacBook Air did this after an external Time Machine drive not ejecting.

I keep getting this (usually overnight), but again just now whilst I left my laptop connected (2021 MBP M1 Max) but unattended in clam mode.

I have an Elgato TB 3 dock attached which has everything connected to it (two 32in monitors, ethernet connection, a usb drive and webcam). It happens every day and I've started pre-empting it and saving and exiting any important work I'm doing before leaving it for long periods.

It's very frustrating. I'm on macOS Monterey 12.2 beta (21D5025f), though judging from the age of these prior posts, it's something that seems to predate 12.2?

Is anyone else still having this, too?

Cheers

I've also been getting frequent kernel panics on an M1 Max MacBook Pro. Pretty consistently. With/without power/USB peripherals connected. I'm on 12.2 Beta (21D5025f), and the error log seems to contain "Sleep transition timed out after 35 seconds while calling power state change callbacks.". This kernel panic usually happens while the laptop is sleeping.

I've already reinstalled macOS from clean as well as followed all the other usual steps. At this stage, I'm hoping this is a known issue and that a future software update makes things a little more stable.

Hey there,
I also encountered the exact same problem with my 14'' MacBook Pro 2021 with apple M1Max processor (currently running under Mac OS 12.1):

panic(cpu 1 caller 0xfffffe0028114a18): Sleep transition timed out after 35 seconds while calling power state change callbacks. Suspected bundle: com.apple.driver.AppleThunderboltNHI. Thread 0x4e98d.

I'm also using a thunderbolt dock (CalDigit TS3 Plus) with 2 monitor (1 with DP, 1 usb-c) and some other input devices attached. Since this is occurring every morning when I fold my MacBook open, I decided to contact the apple support today. The apple employee told be to follow the following steps:
1. make a backup
2. update to Mac OS 12.2
3. check weather the error also occurs in safe mode
4. create a new user with admin access and check whether the error also occurs there.
If none of these steps helps, the employee is willing to pass me through to his superior department. I also asked if he can check, whether apple's development team is aware of this issue, since I'm not the only one with this problem but this can only be done through the superior department, too. Anyway, I keep you up to date.

Cheers

Same problem here. Started with my LG Ultrafine 5k monitor. So far I replaced my dock from Elgato to OWC, installed new motherboard in monitor, new Belkin Thunderbolt cable, updated to OS 12.2, updated LG Screen manager to latest version. M1 Macbook Air and monitor flash on and off intermittently and then I get this crash. It happens regardless of going through dock or direct from computer to monitor and regardless of cable.

So after trying all the 4 steps. (only in secure mode the issue was not there), I contacted apple support again, which told me to install mac os completely new (making a backup first ofc). Since then the issue has not appeared again, yet.

My Ultrafine went back to the LG repair service center. If mine still has the problem I will try that. If it still has the problem (keep reporting on your experience) the Apple authorized service center I use (not the Apple store) told me to bring the monitor and my M1 Macbook Air in to them since they use an LG Ultrafine 5k in their shop and can determine if it's the monitor or laptop.

I was having major issues with crashes on sleep with my CalDigit TS3 and 1 x DP + 1 x TB inputs some time ago, but managed to resolve this completely by downgrading my DisplayPort to version 1.2 on the monitor itself. No idea if this was a true fix or just enough fiddling - i suggest trying it if you find no success.

The LG Service Center experienced the problem when they tested the monitor. So they installed yet another new main board in the LG, tested the original Thurderbolt cable (it was ok) and changed the monitor wiring. The same thing then happened when I set up the monitor. It goes on, then off, then on, then off and finally crashes with the following report. So now both the monitor and Macbook Air M1 are going to the Apple Service Center, who have an LG Ultrafine 5k they use. If this is a faulty motherboard in the M1 Air, it would mean every one of the 3 Mac laptops I've owned has needed one. That's either bad luck, bad karma, bad product quality or if I'm doing something wrong I have no idea what it is since I used the monitor successfully for 4 years.

I've been facing the same issue since I bought my MacBook Air M1 in July 2021.
It happens from time to time when I leave my mb connected to monitor.
I tried with SATECHI Type-C Multi-Port Adapter 4k Ethernet PRO (monitor connected via HDMI to the hub).
I also tried with connecting monitor directly to the MacBook via USB-C.
None of these setups is free from errors.

Sometimes it works fine for a month, sometimes I have this error 2-3x in one week.
I have tested with various combinations of power options and I also reinstalled macOS twice.
Nothing helps.
Any ideas?

OK, got my LG Ultrafine 5k monitor and M1 Macbook Air back yesterday and I'm back in business. Apparently, both the main board in the monitor was bad (it was replaced twice) AND the logic board in the Air was bad and was replaced. The LG service center did not have an M1 Mac to be able to test with the monitor and generally the Apple repair does not have the monitor or repairs them. In my case, Onyx Consulting, an authorized Apple repair center near me in Atlanta, uses a 24" Ultrafine 5k so was able to troubleshoot and determine the problem. After restoring my data backups (since a logic board replacement causes a loss of all data on the machine) and resetting a variety of little things, it's mostly good (more on that following). I'm not going through my OWC dock, which I bought because the old Elgato dock seems to have croaked at the same time as the monitor (I'll have to re-test it but Elgato no longer makes the product or repairs them). The tech told me he wouldn't be surprised if the failure in the monitor main board actually caused the M1 logic board to fail. Perhaps it affected the Elgato dock as well. On initial hookup of the M1 Air to the monitor, I had to do a hard re-start after a laptop crash and so far I've had a few, the last of which was the same sleep transition time out crash I posted previously. I'm just going to monitor (no pun intended) the situation and see how often it occurs. I guess the bottom line here is that if you have an LG Ultrafine and an M1 Mac, it could be either or both products experiencing a failure or perhaps one or the other's failure causing the other to fail. I can live with a few crashes per month as kk44vn posted. I've been without my monitor for so long and just using the 13" screen that I realize what a pleasure it is to use the LG 5k monitor. There is nothing to compete with it other than to go iMac. As it turn out, purchasing an iMac and a laptop isn't very different costwise than purchasing an LG 5k monitor and a Macbook Air together. But I really like to use a laptop in bed on my lap, which is why they call it that, vs. any touchscreen, so I hope Apple comes up with a new 5k monitor series at about the same price as the LG Ultrafine 5k because their new $6k monitor isn't really made for the casual home user.

Well, back to square 1. The M1 laptop seems fine and is not crashing until it's connected to the LG Ultrafine. I downloaded a clean copy of Monterey. Tried all the other fixes...cable swaps, power plugs into the wall, settings, even installed a Mac Cleaner app, etc. The tech wants me to try it again with an additional hard drive wipe and creating a new user account to test again. If that doesn't work we can send the laptop to Apple and I will contact the LG repair center tech again. I have a Macbook Pro Touchbar model and will try that. Two main board swaps in the LG Monitor and a new logic board in the M1 Air so far and nothing works.

To make a long story short, swapped out the power cord but that didn't work. I also determined my monitor was a later production March 2017 with a serial number that started with 703 and did have the RF shielding over the main board. Out of desperation, I moved my monitor upstairs and I got the same results both the Apple authorized service and LG Ultrafine 5k monitor authorized service did. It works fine. I have to conclude the monitor is experiencing an overload of RF despite its shielding. The office has many electronics and wifi devices, including a security system and hvac system main control panels, powered wireless monitor speakers (not using wifi now, using usb wired) plus ATT modem/gateway, an unavoidable nest of wires and a communicating hvac system on the opposite wall in the garage. See photos (monitor goes in center on the VESA articulating arm). Most of these I've encased in plastic split wire loom and clipped together to make as neat an installation as possible. My plan now has to be to try and find (with an RF meter) and then eliminate the source of the interference. The solutions then will be mostly trial and error:

1. Eliminate the portable and easy things first
2. Upgrade the ATT modem to Wifi6 and move it further from the monitor - it's less than 6 ft. now, which was LG's first fix for the RF problem before they added shielding to the monitor (wifi 6 is not just about speed, but is supposed to help with 2.4 and 5.0ghz wifi)
3. put ferrite chokes on all cables, power, usb and ethernet (these are cheap)
4. try a double shielded power cord on the monitor (these have both foil and braid, and it's unknown if the LG monitor original power cord does)
5. purchase an RF shielding fabric/tape kit from Amazon and cover the back of the monitor with it
6. install an RF power filter on any device not connected to the UPS power supply, which has filtering; basically this is just a good surge protector, all of which have RF filtering
7. as necessary, relocate the hvac main control panel, swapping it out with one upstairs, where the main panel was previously located (ironically the previous system, Honeywell Redlink, communicated via RF, where the current Trane system uses wifi)
9. wait for the new Apple monitor
10. hire a consultant
11. move

Are you on the same circuit as that stuff on the other side of the wall? That looks pretty industrial, likely radiant floor heating? If you can find a power monitor/logger, maybe look at what you are getting for power?

Thanks. I considered that. The monitor is plugged into a Cyberpower 1500 UPS which has automatic voltage regulation with an LCD readout, and while there's a lot of stuff in the room, a long time ago we added another circuit to take the load off. I tried the monitor without the UPS and it still crashed.

Try your monitor and computer in a different room like I did after they were repaired. I should have tried this first to see if it's getting some interference in the room.

After a new OWC Dock to replace my Elgato, 2 main board replacements in the LG, a logic board in the M1 Air, as I reported the LG failed again in my office but worked upstairs in the house. I concluded there must be some kind of interference in the office, where I’ve got “command central” with wireless wifi hvac and security control centers, Time Machine, OWC Thunderbolt dock/ac-dc power supply, printer, ethernet switch modem/gateway, Panasonic cordless Bluetooth base station, UPS powered USB connected wireless KEF powered speakers (connected with usb), wireless garage door entry, a rechargeable portable weather radio, a wireless motion alert, an iphone magnetic charging stand and I think that covers it.



To try and cut down on visually on all the wire nest clutter I used white cables wherever I could and if that was not possible I covered them in white split loom cable covers. Extra cable was coiled and zip tied and I gathered different cables together and held them together with Velcro ties.



I did extensive research on what the interference could be and discovered it could be RF (radio frequency), Bluetooth or other

things. I purchased Faraday fabric and tape for the RF to use as an RF shield, but so far haven’t used them.



Finding what exactly is interfering with the monitor is a process of elimination. Here's what I did so far.



1. Unplugged the Bluetooth cordless phone base station and moved the laptop further from the monitor (Bluetooth can cause interference, but the wireless keyboard and trackpad are still in use)



2. Installed ferrite chokes on all both ends of power cords that did not have them; these are RF traps



3. Added surge protectors on all power outlets that did not have them where things were plugged in but not plugged into my Cyberpower 1500VA UPS (surge protectors have RF filters but not all power strips do)



4. Moved the weather radio and wireless motion alerts about 15 ft. away (discovered both of these use the 900mhz frequency and while I did not read that this band is a problem, since I could do this and unclutter my desktop at the same time, I did so)



5. Moved the Apple Time Machine further from the monitor, but still about 3 ft. That's what LG said to do initially in 2017 when they found the monitor did not have proper (or any, they never said) rf shielding inside (apparently it's a plate that covers the main board)



6. Unclipped the zip ties from any coiled cables (coiled cable can pick up RF) and removed Velcro ties from cables bundled

together



I had the monitor connected directly to my Macbook Air M1 and the monitor worked! That is, for about an hour before I had my first crash, with the same 35 second timer error message yet again with the same 35 second issue. My KEF powered speakers had knipshins since only the wireless connection was available. I had the speakers wired connection plugged into the OWC Dock which since I did not have the LG monitor connected to the dock could not work via wired USB. I tried connecting the speakers that way, which I had for years with my Elgato Dock, and they went crazy, switching randomly from wired to wireless.







Now what I am going to do is to move the OWC Dock further away and try it as it is intended to be used, which will be less convenient and in fact require longer cabling. Or I may try it covered with some Faraday shielding fabric. Or get rid of it and go back to a non-powered hub. Or relocate it under my desk (which is a 1 inch piece of quartz Silestone, but shielded with the RF fabric.



And, there's a great article here: https://www.signalboosters.com/blog/wifi6-the-next-generation-of-wifi/ on Wifi 6 and I'm going to get ATT to upgrade me to their new Wifi 6 modem/gateway whatever it takes, since the Macbook Air M1 and iphone 12 has wifi 6. What I learned from this article is that Wifi 6 is not just about speed, but it's as much about less interference from wifi signals, including from neighbors and especially if in close proximity, and a better focused signal, which also lessens signal interference.



I'm encouraged so far that I may, and I say may, have found the source of the problem. I'll keep posting and I hope this helps. I hope that the new Apple Studio Monitor released this week doesn't suffer the same fate as the LG Ultrafine 5k. I'm assuming at least part of the monitor was made by LG. Given inflation over the last 5 years, it would be priced at $1500 vs. the LG Ultrafine 5k's $1300 original price. With the Studio's improvements, it's a good value in comparison.
