MBP 13 2020 won't recognize USB devices from TB dock after sleeping and connecting to the dock. After unplugging the dock MBP crashes and does SMC reset

Device: MBP 13" 2020 10th gen i5

Catalina 10.15.6

Dock: CalDigit TS3+ with firmware 44.1


I'm not sure if this problem is exclusive to Catalina 10.15.6, but I can't say since my dock arrived after the latest update got shipped and I haven't tried if it works on 10.15.5.


Basically, I unplug the dock at night and put the MBP to sleep. After a few hours of sleep it seems to stop recognizing the USB devices plugged into the dock. The dock has a USB audio interface, a logitech wireless dongle (for G604 mouse), a DP monitor and the power supply for the dock. When I plug it after the mac has been in sleep for hours, the mac won't recognize the audio card and the mouse (just the USB issue we had in previous catalina versions with all kinds of USB hubs and USB devices), but the monitor works and everything has power supplied to it, including the USB devices.

If I then unplug the dock and replug it, often the mac straight-up crashes completely and shuts down, powering on with an error that it recovered from a problem ( it also does an SMC reset).


The error report later states: "Intel CrashLog recorded due to unexpected reset".


This reddit thread speaks of the exact same issue with a different monitor and some people with different docks:

https://www.reddit.com/r/macbookpro/comments/i0m9si


Basically, what I'm saying is that the original USB issue is not fixed yet and now it's much worse because:

  1. You can't fix the USB problem unless you restart the mac - re-plugging the devices into the dock won't solve it
  2. The macbook directly crashes and does an SMC reset if you unplug/replug the dock, wiping your unsaved data and crashing anything else you might have open at the time


Additional problem: Monitor sometimes doesn't wake up at all after mac is awoken from sleep. At one point the monitor went to sleep WHILE I was using the mac actively.


I have tried NVRAM/SMC resets and they did nothing.


I wrote an email to CalDigit and they confirmed a lot of other users have complained about this:


"Our engineers have been investigating into the brand new 2020 MacBooks as we’ve had detailed reports from several of our customers who have tried many different brands of docks, from OWC, Kensington, Elgato and ours and none of them have been able to function correctly via the latest chipsets in these Macs."


PLEASE FIX the usb/dock/monitor issues already! This is a problem of Apple devices exclusively. This is unacceptable for a laptop at this price from the year 2020. Cheap off-brand laptops do not have such issues with peripherals!!

I've been having this issue w/ my 13" 2020 MBP since I started using it a couple of months ago, with different dock models.



TL;DR


  • Issue reproduced on 2 different 13" 2020 MBPs running 10.15.7, one running a clean macOS install (no additional software installed), w/ 2 different TB docks.
  • 13" 2018 MBP works fine in all of the (same) tested configurations.




Details:


Since I have the benefit of having multiple MBPs and docks to test with, I'm (not that folks here require convincing) incredibly confident this issue isn't due to some people having faulty hardware (e.g. logic board, dock, whatever).


  • I was easily able to reproduce the kernel panic ("Intel CrashLog recorded due to unexpected reset") on a freshly installed 13” 2020 MBP (clean macOS installation- zero software installed).
  • This is consistently reproduced w/ 2 different 10.15.7 builds ((19H2 and 19H15 - didn't bother to test 19H4 and/or 10.15.6).
  • 10.15.5 (19F2200) works fine.
  • 11.0.1 (20B50 - didn't test 20B29) works fine.


I tested 2 different setups:


  • OWC TB3 dock, with 2 devices connected to it- Dell U2719DC monitor (DisplayPort) and Logitech K120 USB keyboard:

Hello,


I'm experiencing something similar on my MacBookPro13 (2020-touchbar) model Catalina.


The USB devices connected from the Thunderbolt3 dock are not recognized properly, and the audio interface may or may not produce sound.


The problem is not only with CalDigit's Thunderbolt3D dock product, but also with other audio interface manufacturers.

Hello,


What specific MacBook configuration or Dock is that?

Can you also give us the details of the Thunderbolt and Type-C ports on the device?


I found this article and it seems like Apple has not been able to solve the problem.

First of all, that is a completely different issue.


Second: it's been discussed over 23 pages long here that you either upgrade to Big Sur or suffer forever since it doesn't seem feasible for Apple to invest time in fixing this issue on a previous OS - apparently.


Third: why can't I unsubscribe from this thread already? :D I mean I've clicked at least twice on the "following" button and watch it change status, only to receive yet another email from here and see the status revert.

I have a problem which seems related to this. I have a Belkin Thunderbolt 3 dock plus. Several times per day when my computer is connected to the dock, waking up causes the MBP to completely and suddenly shut off. When it happens the cooling fan spikes for a second or two then it is done. Power goes off and any work I had not saved is lost. This is infuriating.

I just started having this issue with my early/mid 2020 MBA on Catalina 10.15.7 connected to a Dell monitor. I suspect it's triggered by the monitor going to sleep because my MBA is set to never sleep. Also, the MBA just shuts down instead of restarts. Each morning for a few days now, I come into my home office and the MBA is off. I'm installing a security and safari update now. If that doesn't fix it, I'll have to set the monitor to never sleep I guess.

Hello


I have the same issue with and without using a dock: mbp 13-inch 2020 OS 10.15.7


Sent MacBook to sleep after ejecting and disconnecting external volumes. Next morning volumes are not recognised when reconnected. Only thing that helps to have them recognised is to restart the MacBook which causes kernel panic.


I have this probably for about a year now. First blamed it on my USB to TB hub and antique external HDD that I used for time machine. Half a year ago I replaced that setup with obscenely expensive OWCENVPROTB3 which connects directly via TB3. The issue persists.
