Big Sur panic when connect/disconnect usb-c dock

Big Sur panic when connect/disconnect usb-c dock (tested with many usb–c docks including baseus, ugreen, non apple – not reproduced with apple multiport adapter).

Problem persist! I have many panics every day!

  • I have a 16" 2019 MBP running Big Sur 11.4 and I'm use an HP Thunderbolt Dock G2 with my monitors connected via USB-C.

    I get this all the time. Sometimes it can be all of a sudden in the middle of a session, but it is much more prevalent when I am plugging in/out of the dock. It also occurs when the laptop wakes up after being in sleep mode. I get the quick sound of the fans blowing and then it reboots. It happens way too many times. I have no other option in terms of trying other docks.

    I report the error every time I get it. It has been going on since the Big Sur upgrade.

  • Are you connecting your monitor via DisplayPort? Try using HDMI instead - my laptop only crashes with DisplayPort, never with HDMI. Also, try connecting your monitor without the dock (get a USB-C to HDMI cable) to rule out a problem with dock

  • Happens to me as well as described by @dbdotconf. I use 2 monitors with 16'' 2021 Big Sur 11.5.1. The same flow of actions, almost every day when I plug in monitors via 2 TB3, I hear fans and then it crashes and reboots. Also send report every time. This is very annoying. Such amount of money was paid not for such an experience with Mac which is supposed to be ideal.

Wait for macOS 12? :( Cant use external displays... Working with only the internal display is very disappointing. When you connect an external display, the operating system crashes.

The problem still exists with macOS 11.4, when connect with my CalDigit USB-C Pro Dock.

  • I have had the same kernel panic issue since upgrading to 11.3. I have a 2019 MBP 16 and a HP G5 TB3 dock at work and home. The issue only seems to happen when moving between the two docks. I can plug/unplug from the same dock without issue, but if I move to the other location and plug into the other dock it will crash 100% of the time (even though they are the exact same model). I have tried waking from sleep and waiting 5-10 minutes before plugging in as well as plugging in and then waking from sleep, neither method helps the issue. I did not see the issue on 11.2 and earlier, and am still seeing it on 11.4.

Same problem for me for the last 6 months. Connecting a Dell or Belkin USB-C hub with a Dell U2718Q monitor attached (and on) make my MBP 16 2019 crash. Even switching on the Dell sometimes makes the MBP crash. I wasted hours with the Apple support. They even asked me to do a fresh install which I did and again wasted hours. Update to 11.4 didn't solve the problem.

Apple, where is our support? When this issue will be resolved? The panic crash happens each day!

Apple obviously doesn't fix bugs anymore but introduces new ones (like HDR video playback shows white windows on external displays). And doesn't care about it. The devices are obviously not meant to be used anymore, WLAN, Bluetooth, keyboard, screen, these are all things that should better not be used. Just like the sleep mode.

The software is too unstable, so that there are constantly problems, errors up to daily multiple kernel panics.

And instead of fixing them or at least transparently telling you that they are working on it, they just recommend you to buy new hardware or waste your life to reinstall broken software, which only frustrates you even more, because it doesn't solve any bug in Apple's software.

+1 on this 16" 2019 MBP 2.4 GHz 8-Core Intel Core i9 32GB 5600M 8 GB System ramps fans for a second then reboots when plugging in any external monitor, via a dock or EGPU. Running Big Sur 11.4 (20F71)

This only started happening after I tried booting hiveos.farm from an external USB stick, is this a zero-day / virus? Have done a clean install and restored from Time Machine, with the problem still persisting.

Similar problem here. It happens when I connect to my dock, or I play with cable of external monitors. Also when the macbook pro goes to sleep then wake up, it can only detect one monitor. If I plug/unplug the cable of the other monitor, panic happens.

Been getting this since BigSur - seems to happen all the time now w/ 11.5 Beta (20G5023d) as well... frustrating because I opt'd into this to try and solve......
