BridgeOS Crashes Happening on 2018 MacBook Pro with TouchBar

To add a bit of an update, and really only related to Power Adapter usage (although I had a couple of hours on battery only last night and everything was ok) -

In energy settings (Power Adapter tab) I unticked -

1. Prevent computer from sleeping

2. Put hard disks to sleep when possible.

I have not had a (Bridge OS related) KP or restart since my last post (48 hours ago).

It may be worth a try if you're running a MBP that's constantly connected to AC.

I've also been troubleshooting a new Drobo 5N2 (NAS) that I purchased alongside the MacBook Pro. I found when clicking on or sometimes dragging files from folders within my Drobo shares to my Mac (or into Photoshop/Adobe etc.) this resulted in Finder beachballing for 20 seconds, the Finder window closing and my favourited shares/folders pinned to Finder to be deleted (this has happened probably 20 times in the last 10+ days with huge frustration in having to recreate favourites). The Drobo would also disconnect momentarily - a couple of times the Drobo wouldn't connect, although it was visible in Finder. I would have to manually connect to server to get shares to mount.

These 'mini' crashes in Finder were happening in High Sierra as well as on the latest build of Mojave, and in tandem with the Mac's Bridge OS crashes - for this issue I've been going backwards and forwards for a few days with Drobo thinking it's a Drobo thing.

Drobo are unable to see any issues via diagnostics regarding a Finder crash I had yesterday (not full blown KP/restart/Bridge OS error) - the crash again removed all my shortcuts from Finder favourites and disconnected the Drobo momentarily. This has led me to believe there's nothing wrong with the Drobo and this is all coming from Finder/MacOS.

Googling 'Finder crash/favourites being deleted', I had no idea this issue has been going on for (MANY) years. This is pretty basic functionality that I would have thought ran smoothly every time. I mean they're just pinned shortcuts.. either way, this is very broken (for me) in the latest Mojave PB.

Is anyone else losing their pinned finder favourites after these major KP crashes?

Out of interest if you go to > Apple menu, About This Mac, System Report - Under 'Thunderbolt' (left side) - what firmware version are you running?

I have a Caldigit TS3+ dock and stumbled across this article this morning (from April 2018). http://www.caldigit.com/KB/index.asp?KBID=228&viewlocale=1

I fail to understand how a new machine, purchased 3 weeks ago AND now running the latest Mojave beta was shipped with such an old Thunderbolt 3 firmware version. My machine is running Thunderbolt controller firmware 30.2 - I'm awaiting a call from Apple support now on how to upgrade the firmware to 33.2.

My rebuild went smoothly. I reloaded everything from the App Store and by re-downloading fresh binaries from their publishers without restoring anything except some VMs and a couple of data folders or by re-sync with iCloud and Dropbox. All settings are now default, including FileVault (on). I am in day 2 with no restart, but it is early to tell.

Interestingly, the first thing I tried (again) was installing a Bootcamp partition with Windows and it went flawlessly. I can boot to the new Bootcamp partition or use it through Parallels. So, that is great. I am going to avoid using the Bootcamp version of Windows until all of this settles out a little, though. I only need to be on hardware for one specific type of work task. Otherwise, I will used VHD based VMs whenever possible.

The only issue I have seen since the reload, which continues to make me nervous, was I could not erase a USB flash drive (new out of box with NTFS format) until the 4th try without some sort of Disk Utility error. My main non-reset symptom continues to be odd behavior with external drives.

I ended up returning the MBP 2018 40 days after the standard return window -- they didn't put up a fight, they know this is a real issue affecting a bunch of people. Keep contacting support, and consider a return until they fix their shiz!

It crashed 3 times while I was sitting in the Apple store. RIP.

Hello 湖北武汉, Kindly tell me which secure boot mode do you use? https://support.apple.com/en-us/HT208330 Did you try to install below update? I'm not sure it will fix your problem or not. https://support.apple.com/en-us/HT209081

Mojave 10.14.1 was released Tuesday after the new products announcements, and accompanied shortly thereafter by a Security Update for Mojave, High Sierra, and Sierra (but NOT El Capitan).

Have you tried the new updates to see if they snuck in any improvements?

A user suggested to do the SMC reset twice in a row.

Im free of kernel panics for more than 48hours!

I can only encourage you to try it out, but be aware of the new procedure for Macs with T2 chip!

(Hope you will be redirected to your country page 😁 )

I will keep you updated!

If you are getting panic reports that clearly indicate BridgeOS panics, then Contact Apple Support. Only they know what to do about that specific issue.

If you are getting a different panic, or hangs, or Application crashes, or anything else, please start a new thread with a distinctive Title that will get you the personalized attention you need. We cannot possibly debug a different issue on this already overflowing thread about BridgeOS panics.

hi, when you see crash during sleep, are you seeing the "macOS watchdog detected" panic in in /Library/Logs/DiagnosticReports/ProxiedDevice-Bridge?

Happening to me as well. Just happened a few minutes ago after about 30 minutes of sleep and a re-wake where I am told that there had been a shutdown.

Have a support ticket and I am supposed to get a follow up call this morning from Apple Support.

Shows abnormal shutdown.

End of report

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.

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.

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.

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...

I think this is related to secure boot (full security at the very least).

I've disabled most of the T2 functionality. Power nap is disabled. Disk encryption was disabled, but I went a few days without it crashing during sleep so I re-enabled that. That ran fine for a few days. Then I turned on Secure Boot with Full Security. I got a kernel panic in the middle of the night while it was sleeping.
