BridgeOS Crashes Happening on 2018 MacBook Pro with TouchBar

We'll all be interested to hear if that fixes the issue for you. But if that is the fix, then I'll be ****** because it's taken me 3 days to get this machine back to the state of my old machine. I wonder if a full disk erase and fresh OS install can be followed by a Migration Assistant?

As it happens, I had to wipe clean and restore the first day. So, no difference. I am still having the issue. I started with Migration Assistant coming from my MBP 2016 over Thunderbolt and there was some sort of disaster. After the end of the process, the screen was not readable with only gibberish like the fonts had blown up somehow. So, I deleted the volume and did a ground up restore. I did reattempt Migration Assistant and it worked great (and fast) the second time.

Summary being, at the end of a long day 1, I had migrated twice and formatted and restored once. Anyway after all that I am still having nightly spontaneous restarts. Really wish I did not sell off my MBP 2016 so fast. This is killing me for work.

Being the paranoid type, at the end of this journey I will feel like I have to rebuild again given how many hard crashes have occurred and concerned about the status of the disk contents.

Thanks for the EtreCheck report. I think we can definitively say that a -20 is no longer "Unknown". No fix for it yet though.

Support has asked me to disconnect everything to bare MacBook and power adapter, then sleep and wait to see if it happens again. I'll do that, I guess.

I am curious if others on the thread are experiencing this with bare machine and nothing connected. Typically, mine has monitors and a lot of devices attached.

Are you having the problem before and after the supplemental update for MBP 2018?

Last night, before going to bed, I intentionally set the environment similar to when I had my BridgeOS panic:

MBP 2018 is connected to MBP 2015 through thunderbolt 3->2 adapter and cable.

Belkin USB C Express dock connected.

Other peripherals like ethernet, printer, scanner are connected through the dock.

Well, it didn't crash or auto rebooted. The difference I can think of is the supplemental update although it could be more. Will be watching closely...

It's been about 6 hours since I erased the disk, reinstalled the latest High Sierra, then installed the Supplemental update. This was recommended by Apple tech support.

Since then I have tried 10 or more sleep/wake executions and so far no recurrence of the BridgeOS panic. I have power nap and wake with Apple Watch enabled. I am not connected to any peripheral devices -- just the computer and power cable.

Of course I probably jinxed it by posting this...

I’m trying the same now. My crashes all happened in the middle of the night during sleep, and the latest one was 4 days removed from the previous, so I don’t think I’ll know whether this worked immediately.

The crypto var errors are gone after wiping the disk at least, though I’m not sure if this is relevant.

By the way, the panic log says "bug_type":"210" for everyone reported so far.

Incidentally, got to know this command. And would it be the reason?

$ macerror -210

Mac OS error -210 (buffersTooSmall): can not operate in the memory allowed

Curious how everyone is doing affected by this issue...

As for me, I have not experienced the Crash after waking from sleep ever since disabling "Enable Power Nap" in System Preferences > Energy Saver. I still have the crypto errors on my disk when running Disk First Aid though.

Also, an Apple representative named Violet called (and emailed) wanting more information and referenced this thread. I was unable to connect with her, but it's encouraging to know that they're looking into this.

If a full erase of the drive followed by a fresh install seems to solve the issue, I'm OK with that if I can install my personal files with Migration Assistant or from Time Machine. But the thought of reinstalling everything from scratch again makes me want to cry.

I'm following this thread as I'm having the same kernel panics referencing Bridge OS & bug type 210. Mine also often happen when I pickup or move the computer around. I got the computer (15" 2018 MBP) yesterday and had maybe 6 or so yesterday and about 4 so far today. Something is very wrong & I hope for a fix soon!

Mine just had its first crash since completely wiping the hard drive and reinstalling everything. Bridge OS Error again during sleep. Woke up to the "your Mac has restarted due to a problem" message. I had only the power cable and a Thunderbolt 3/2 adapter (with no TB devices powered on in case the frequent waking of the monitor was the culprit).
BTW, you can find these panic logs in /Library/Logs/DiagnosticReports/ProxiedDevice-Bridge within Console.

I’ve had two nights without a crash now after support asked me to disconnect everything but power. Interesting. When I finish working, I shut down and disconnect everything, move it to a desktop, start back up and let it sleep. I have power nap on and wake with watch on FWIW.

I actually went three days without a crash earlier this week. Unfortunately it has crashed twice since then.

I'm concerned if people are accepting that they need to disconnect everything from their computers to avoid a crash. These certainly aren't "pro" machines if you can't plug anything into them or let them sleep.

Hey folks,

i have this problem since March/April this year ! (had the 15'' 2017 maxed out modell)

Now I am running the new 13" i7 Modell from 2018 and it happens over and over again.

Today I wiped everything once again, no migration, no backup - and it happend just seconds ago, while running - suddenly my external peripherals werent accepted anymore , so my external soundcard shut down -> no sound

I restarted the mac : right before it went completly off the FAN speed went to the MAX , after several seconds Log In window and again the kernal panic / memory stackshot bla bla :macos_system_state":"running","bug_type":"210"

I ll think im gonna return this little beast and wait for the iMac to come alive ... its sooo annoying

Totally agree. I got the maxed out version at over $7k w/Apple care and tax. Pretty much a month’s income for most. I am a heavy user of virtual machines. As an EE and developer myself, I get how hard these things can be to isolate and how disparate things can interact. Just trying to get Apple support any info I can. That said, Apple is one of the highest valued companies on the planet with 10s of thousands of people begging to work there. It was disappointing to hear this issue may have started with iMac pro so the runway for the solution is longer than just a couple of weeks. I am hopeful they’ll apply whatever resources are necessary. I had been resisting all the Thunderbolt docs. I ordered a Caldigit dock today to clean up all my device connections. Just to make troubleshooting a wee bit more interesting.
