BridgeOS Crashes Happening on 2018 MacBook Pro with TouchBar

Quick update from my side:

Called with Apple Support today and spent some time doing the standard resets (NVRAM/PRAM, SMC) and they advised me to do a clean install of Mac OS. So, following their advice I erased my disk and started doing a clean install.

After about 3 minutes into the installation process my MacBook crashed and restarted, corrupting the installation.

Now the laptop has no OS installed and I can't get it installed either, since the laptop keeps rebooting during installation.

Guess I'll have to get it replaced now...

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.

I've had my machine (15" i9) for about a week and i've experienced 4 crashes. For the moment, the pattern here is that I closed the lid while charging. A few seconds, the fans spin up full blast. Opening the machine again reveals it is starting up again. Logs show BridgeOS causing a full panic and global reset. Rest of the info too cryptic to make any sense out of...

Called Apple support - very friendly, but the person I spoke to doesn't seem to have heard of the problem and didn't seem very interested in what the console or the crash logs showed. Recommended the same as above (NVRAM/SMC reset, backup + reinstall) but i've little faith this will solve much, if anything... It'd be nice to get an acknowledgement from Apple that it is being looked at/worked on.

A little update on this topic.

Of course, that 24 hours are not an indicator, but anyway it worth to try.
Go to Settings->Energy Saver.
1. UNCHECK automatical switching between the GPUs (if exists of course)
2. CHECK prevent computer from sleeping automatically...
3. UNCHECK put hard disk to sleep

4. UNCHECK Power Nap (regarding)
5. Turn display off after: - NEVER

I will update this topic if everything is fine.

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.

I've got a new 2018 13" MBP -- have had around 8 kernel panics. Sometimes plugged in, sometimes not, sometimes while the device is being used, sometimes while it is not.

The fan whirs loudly for a second and the device shuts off suddenly.

For 7 of the 8 times there was no diagnostic log or message. For the most recent I finally got a crash log...

Good to know that you are also running into SMC being one of the culprits! The idle thread call could be a red herring. But more reports from other users will hopefully confirm one way or the other.

I am currently testing my default setup with all checkboxes enabled in the "Power Adapter" tab and all except Power Nap is checked in the "Battery" tab. And I have automatic graphics switching enabled.

I have the same issue.

didn't connect to anything, it was in sleeping mode. when took it out, it already showed the information of some issued caused the crush ( i remember it says Bridge 2.4.2 causing the crush)

called apple see what's next. if it's crushing again i might have to send it back and get a refund since it's still in 14 days.

MacBook Pro (15-inch, 2018), macOS High Sierra (10.13.6), 2.9Ghz i9, 32GB RAM, 1TB SSD

I'll start off by pointing out that this is the second MacBook Pro in the last 3 weeks which has the same issue. The first MacBook Pro (2018 15'/16GB/1TB) started crashing a few days after using it. At one point crashing 4 times in a single hour. After working with the Apple support team it was determined this was a hardware issue. The crash occurs anytime my computer goes to sleep with a bridge OS failure when it starts back up. Rather than replacing it I returned it since it was still under the 14 day policy (which I found out is actually 30 days but thats a separate story).

I received my new MacBook Pro order Tuesday with the same spec computer. Almost out of the box it kept crashing with the same issue which is what lead me to the Apple store today.

After waiting the "Apple Store Minute" I met with a Genius Bar tech who ran a system test on my computer to test the battery, keyboard and other general hardware things. Then he tested the Touch Bar specifically to better understand my issue and my computer started to act up.

My computer started having trouble connecting to his system and he kept having to restart the test to have it only fail or not connect at all. THEN my computer started to overheat in the area where the Touch Bar was. My computer then display an error on my computer screen that stated my computer was overheating and thats when the tech had to cancel the test.

He said there was definitely a hardware issue with my computer (mind you this is my second one) and recommended a replacement or return.

I spent the rest of the evening on the phone with Apple trying to find out what the heck is going on with their computers. I didn't get much help in that area and everyone keeps giving me the run around.

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.

Also seeing AppleSMC crash. (below)

Energy Saver settings are everything checked except

[Power Adapter]

prevent from sleeping

[Battery]

Power Nap

Graphics switching is enabled

I use my i9 MBP as a desktop replacement. It's connected to a StarTech TB3 dock, which provides power.

The lid is only open when I have to login after a crash so, in my case, it isn't related to transition from lid open to lid closed.

It crashes once every 72 hours or so from the day I got it on 19 July.

Most of the people do not care about the real reason. But they just want to find the solution against this annoying crash.
By the way, I enabled "Switching graphical adapter" - no crashing

I suspect that (at least in my case) the Bridge OS crash was caused by features "Going computer sleep when display is off" and "Put hard disk to sleep".

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.
