BridgeOS Crashes Happening on 2018 MacBook Pro with TouchBar

I have just received my replacement laptop and the problem still persists. I would say this is a software problem rather than the hardware fault they originally diagnosed.

I set it up initially without migrating any data and it still crashed.

I have tried turning off power nap and it still crashed.

I have been on the line to apple support and sent them diagnostic info.

I've had the same problem as well. So far two BridgeOS crashes while sleeping. I also notice that the audio will sometimes cut out on youtube and will only come back if I close tabs and hard refresh the page. Not sure if it is related in anyway. My 14-day return window expires tomorrow, not sure what I should do.

This sounds alarming. It’s not just a T2 chip issue as some reported on iMac Pro. Maybe all Tx chip issue or general OSX problem? I am still using 2014, 2015 MBP 15 which have never this issue, though...

I do use Parallels, but since working on this issue, I leave it turned off unless I am actively using a VM. So, all of my crashes have been with Parallels not running. Generally, if I am actively working, it doesn't seem to matter what is connected and what software I am using. Sleep brings on the behavior. At least for me.

The only other issue I've found has been that my system now hates to back up to external hard drives. Either TM or Acronis. In mid backup it looses the drive or has a drive error. Cautiously, I would say that I am OK if I direct connect the drive to a native port on the machine rather than through a hub. That has now worked a couple of times. I'll continue to test that aspect. It could be my hub, or Acronis or something else. What stands out to me is that I literally picked up my MBP 2016 and dropped the 2018 in it's place with the same wires and devices connected to the same ports. Now I have the sleep issue, am having trouble with my two external drives working reliably and of course Bootcamp isn't ready yet. I am on my 3rd cycle of formatting and starting again with a fresh initial backup. I trust all of this will get better and hopefully an OS update will come soon.

The iMac Pro has the same T2 chip. The older machines with the T1 chip don't seem to have this problem.

Just out of curiosity, has anyone seen this crash while using the macOS Mojave beta?

As I mentioned, I've not experienced the issue ever since turning off Power Nap, though I understand that's not working for everyone.

If the panic crash is related to T2 chip, do you actively use touch bar? I’m wondering if someone who don’t get panic use less frequently the touch bar.

T2 does a lot more than touch bar. But my panic happened around the time when I modified the touch bar setting and used a lot. I also found a bug that sometimes icons are not aligned as I configured. Maybe this could be a triggering action of the panic crash?

Finally connected with Violet at Apple Support. Went through some things, like generating a System Diagnostic through Activity Monitor. In the end, they wanted my machine so they could try and understand why turning off Power Nap is alleviating the crash for me. So a new one is ordered and I'll send this one back to Apple once it arrives. In the meantime, I've reenabled Power Nap to see if I can get it to crash so I can send Violet the results. So far, both putting the laptop to sleep manually and letting it sleep on its own have not resulted in the crash upon waking it up, so who knows...

FWIW, I'm using a USB-C/Thunderbolt 3 to Thunderbolt 2 adaptor to connect to an OWC Thunderbolt 2 hub. And again, ever since disabling Power Nap in Energy Saver System Preferences 5 days ago, I have not experienced the crash. And even though I reenabled Power Nap yesterday to try to make it crash, despite multiple "sleeps" since then, it has not crashed. Go figure.

Having this issue, as well. Picked up my 2018 15-inch i9 on Tuesday, set up via Time Machine backup. CPU experienced kernel panic overnight while plugged in to an OWC Thunderbolt 3 dock, as I came back to find it had shut down. Brought the machine into work the past two days, where I've left it at the lock screen while connected to power, only to come back and find the same thing has happened two more times. Thought I was in the clear after turning off Power Nap after the second panic, but just experienced again about an hour ago.

Keeping an eye on this thread for the (hopefully) eventual fix.

The latest replies to this thread aren't showing up for some reason.

Anyway, to the last few posters: was there anything connected (even if it wasn't powered on) when you experienced the Bridge OS crashes? Particularly a Thunderbolt 3-> Thunderbolt two adapter.

My first machine was crashing on wake from sleep almost every time with nothing connected.

I received my replacement on Monday. It initially crashed 3 or 4 times but then just stopped crashing.

It has been running 3 days with no crashes now. I re-enabled powernap and hey siri yesterday and still no crashes.

I also should mention I registered a card for apple pay on Monday as well. No idea whether that contributed to anything, but there were no crashes since the registration.

My experience has been that if I have things connected I get the crash. If have nothing connected I don't. I don't have a TB3/TB2 adapter. I have a USB 3 hub, an LG 5K monitor with its embedded usb c hub and an Anker adapter plugged in to that with wired ethernet port and a couple more USB ports. I have two drives connected to the hub, a headset, a microphone and a Logitech unifying receiver.

FWIW, my interaction with support has been excellent so far. I reached out to them and later they reached back. I know better now how to collect diagnostic info for them.

I have experienced the same crash with only the power adapter connected while in sleep mode.

I also see the following errors in Disk Utility > First Aid

warning: crypto_val: object (oid 0x4): invalid state.major_version (0)

warning: crypto_val: object (oid 0x4): invalid state.key_os_version (0x0)

warning: crypto_val: object (oid 0x4): invalid state.key_revision (0)

These are the same errors that many other with the same kernel panic have noticed.

Yes, those errors seem to go hand-in-hand with the crashing I believe. However, even though I still have those errors, I can't get my MacBook to crash now. I've tried using it connected to peripherals and by itself with PowerNap reenabled, letting it both fall asleep by itself and putting it to sleep. Nothing...working like a charm now. Sure wish I knew what I did so I could tell you all.
