BridgeOS Crashes Happening on 2018 MacBook Pro with TouchBar

Apple called me two evenings back regarding my post here. They were quite interested to learn what they could — I informed them, sadly, that the unit in question was back at the Apple Store, as I have exchanged mine for an identical (though slightly newer) unit.

Now I'm almost hoping this one panics, so we can get to the bottom of it.

Hopefully they get a hold of my old machine and can reproduce it with that hardware.

So brand new replacement unit from Apple. First crash since installing it as described in my earlier post. About 60-70 hours before the first crash. Same as before "BridgeOS....". This is similar in time to my first machines crash. Was a couple of days after installing it before it crashed. I was hoping that having eliminated the crypto error on disk health check that it might have helped but doesn't look like it.

Now my dilemma is this .... do I abuse Apples good faith policy of returning the unit within 14 days and get another one and another one and another one until eventually this is resolved through either hardware or software ? Setup time is only a few hours - a little painful but hey I extend the apple care by 2 weeks every time and Apple will certainly be feeling the pain of all these return units ?

I jest. Not the right thing to do .... will be keeping this and live with the crashes till Apple fixes it.

Hello,

I have the same issue. As it was mentioned above - ~ 2 weeks everything was fine. And then the issue has appeared.
My mac - MB Pro 2018 15" 32 GB RAM, core i9, 2 GPUs.
So now I perform different experiments to find at least the shadow of the real reason.

But I wanted to say a few words about Secure Boot.

Here I found an interesting article [Fixed] Windows 10 Hangs on Secure Boot

As I understand - the issue should be known in the hardware engineering circles.
So, let's hope that it will be fixed for Mac as well.

Andrew, can you give me a bit more information on your crash? I am not super technical term savvy, but I have been having tons of crash issues with my new 13" as well! Love to see if they are related and if anyone has a resolution. I just posted a question and described my crashes. Maybe they are similar.

Given that the problem occurs when these machines wake from sleep, disabling the ability for it to go to sleep in any position but "unplugged and closed" is not a terribly helpful idea as a solution — though it could provide diagnostic data, I just wanted to underscore that this is not solving the problem directly.

But as diagnostic tests go, you are changing too many variables in this one step. Did you test after each change? If we're going to science this, we need to test one change at a time....

Update after nearly a week with my new machine.

First, no crashes, no panics.

Second, its thermal management is far better than the prior machine. Running a type 1 prime95 torture test with 12 threads my prior machine (after the throttlegate™ fix) would sit right at 2.2Ghz while at 100% utilization. This new machine heats up to the same temperature, uses the same power, but runs the same test at a solid 2.7Ghz.

Something seems to be improved since the first week of production.

Please, try the steps from "Energy Saver" comment above.

I did, it still crashed during sleep again with the same Bridge OS error. This is now 9 times in 3 weeks.

Nothing was attached except for the power cord. The lid was open (if that matters), and no applications were open.

It's such a shame that your solution is to turn off a feature and cross your fingers. All after formatting a brand new computer because Apple still haven't fixed the issue that seems to be in the image used on the new MacBook Pros and secretly thinking you're in for Bridge OS kernel panics at some point.

Hey guys! I have the similar problem (mb2018 15') and I very tired( Why we must suffer from the problem. New update today not solved a problem for me. I using DOCK station and USB-C usb3 adapter (does not matter - I do not believe 2 adapters can have own problem) and I have the problem. I have contact support - their answer does not like me - "You must wait. Engineers working on this software problem - in future, they fix it - without deadline!!!" it's not serious - I'm very disappointed Apple (I must work to be able to buy Apple production - but with that, I can't work). I want to return my MB (and buy MB2017 without T2 - right now, I can't see an alternative for MacOS). Did anyone return MacBook after 14days - bought appleStore (guarantee return in Russia)?

Yep! We've the same Bridge OS kernel panic problem on TWO brand-new 2018 MacBook Pro's with touch bars, one 13" and one 15".

One has never had external devices connected, the other has had monitors and external SSD's & HDD's.

Both crash when they've been in sleep mode for some time.

So wishing we hadn't "upgraded" from our 2009 & 2012 models. Not looking forward to migrating our changes back to the old machines and returning the new ones.

Dear Apple,

Your products MUST be reliable for them to be used for work. All other features are optional. Please do not release unstable machines and make your users beta testers. Therein lies the dark side and loss of market share.

Your sincerely,

Losing the Faith.

Hi Grant,

Oh, I know, it was kind of sarcastic humor. Of course, that I have reported already a few bugs. And I'm sure that apple aware of the problem.

But the interesting case is that today the crash happened not because "bridge os", but because of "mac os".
Probably, there are people who had the same and could share their thought.

Hey Oliver -- unfortunately I decided not to replace the machine. It simply is not worth the risk to my time and energy to deal with the problems.

I'm likely going to wait for the new laptops that are rumored to come out in October, and even then wait to make sure they're not collective lemons...

Hi there folks,

This thread seems to have quietened down a lot. Does that mean the problem has been fixed for most people?

I ask because I returned two faulty machines a month or so ago and want to know if it's now safe to buy some new ones.

Cheers.

I also got a bridge OS 3.0 crash, but it was not during normal operation -- I had let my battery completely drain and I tried to start the computer after it had gone to sleep, but without power connected yet.

When I plugged it into power and booted it up I was met with a "your computer restarted because of a problem" message.

I'll keep an eye out for more crashes like this.
