If Zoom is crashing your Mac

That’s fine. You wouldn’t be able to do what I was suggesting anyways since you don’t have a T2 chip in your Mac and your issue is entirely different from everyone else discussing the kernel panic issue in this thread.

Using an external monitor also seems to prevent the issue, my guess is that it switches permanently to the discrete GPU / Radeon Pro in this situation.

All the crashes I experienced were without an external monitor, when the MacBook switches dynamically from the Intel UHD Graphics to the Radeon Pro.

Waiting for 10.15 Catalina, you might want to try to disable the Graphics switching in the energy saving preferences. This will drain your battery faster though (but Hangout/Meet is anyhow a disaster on this aspect).

You can also try to disable hardware acceleration in Chrome (I didn't test long enough to confirm an improvement)

This happened to me yesterday too. It's exactly like others have described.

Using an app (any app, including Apple's apps) with the built in webcam on my MBP (15-in 2018 model, purchased only a few months ago refurbished) - causes a freeze within a few minutes, then the laptop powers off and restarts without warning (a kernel panic). This is preventing me from joining via webcam to video conferences (I'm a remote trainer, so my life revolves around video conferences).

This is not a third-party issue, it's a MacOS issue as it's happening across apps.

I can't believe a bug of this size got past QA, absolutely appalling and irresponsible on Apple's front.

I have found a workaround in the meantime - plugging in my USB mouse (Microsoft standard USB bluetooth mouse with an adaptor for the USB-C on my MBP) seems to keep the system stable and not cause a crash. while using my webcam in Zoom (going on 34 minutes now, before it was crashing within a few minutes).

Hopefully this gets fixed soon...

I am experiencing the same issue and I think the more voices we have it might bring the management awareness!!!

It's really disappointing to see this reaction from Apple after buying the most expensive laptop in the market

Yeah I was hopeful too but 18G103 does nothing to the Boot ROM/BridgeOS which is where the issue lies. I’ve been going around with a 16GB flash drive with the latest Catalina Beta installer on it and a 256GB flash drive that’s wiped in APFS format and “installing” Catalina to it on afflicted Macs. This forces the internal BridgeOS to upgrade which fixes the issue. It’s about a 30 minute process but it’s a solid fix

Can confirm that booting from an external hard drive with MacOS Catalina beta without installing it on the laptop resolves the problem on MacOS Mojave. I had several Facetime video calls in the last days which lasted over an hour and my MacBook Pro 15" 2019 didn't crash at all. Annoying fix but it works.

I'm amazed that users managed to find the issue before Apple's QA, diagnose and pinpoint exactly where the problem lies before Apple's engineers, and find a (somewhat) nice workaround... while Apple did nothing at all.

Can confirm, Catalina's boot also fixed the issue for me.

We had the same issue and this is what worked for us.

Disable automatic switching. This can be done from the following location:

System Preferences > Energy Saver > Automatic graphics switching.

What is the solution? I’m going out of my mind. $3,500 brand new Mac purchased specifically to use zoom and crashed on my 4 client zooms. It’s been back twice. They cleared it. I lost everything (my error back up). And again they blame zoom. All apple can tell me is to buy a new Camera to attach on the laptop which will be more comparable with zoom. I know don’t use my laptop for clients as I am not confident it won’t crash. How pathetic is that for Apple $3,500 laptop. What do the rest of you do? Have you purchased another camera to attach onto your laptop and that worked?

It has nothing to do with Zoom, nor with your MacBook camera. It is an issue with Mohave 10.14.6. If you review previous posts in this thread, you will find this confirmed with more details. Apple is aware, but has not shown any interest in fixing Mohave. You have two options, both of which worked for me. First is to use an external USB camera. Sucks, but Zoom will then work. Second is to upgrade to Catalina. Once I installed Catalina, camera works fine with Zoom.

For what it’s worth, in Mohave 10.14.6, using any app with the camera will cause the crash—FaceTime, GoToMeeting, etc. Any Apple tech blaming it on Zoom is really irresponsible.

Fix is to get the BridgeOS version updated to 1037.0.78.0.0 (iBridge: 17.16.10572.0.0,0)

If you are not ready to upgrade to Catalina (because let's face it, it breaks a lot more than it fixes for most), do the following workaround:

1) Download the latest Catalina installer (but DO NOT run it to your internal SSD).

2) Get a 32GB flash drive that you can attach to your Mac and format it into APFS format (in Disk Utility you must change the view to "Show All Devices" rather than just "Show Only Volumes" which is what it defaults to)

3) Shutdown your Mac

4) Boot up into Recovery Mode (Command+R)

5) Go to Utilities>Startup Security Utility

6) Choose to Allow booting from external media

7) Quit and reboot your Mac

8) Launch "Install macOS Catalina"

9) Change your drive destination to your APFS formatted flash drive

10) Click Next and let Catalina install on the flash drive

11) When the Mac completes the install it will come to the Welcome Setup Assistant

12) Reboot your Mac and disconnect the flash drive

13) Your internal drive with macOS Mojave will boot back up

14) Go to About This Mac

15) Go to System Report

16) Confirm your Boot ROM Version is now 1037.0.78.0.0 (iBridge: 17.16.10572.0.0,0) or something similar rather than 220.270.99.0.0 (iBridge: 16.16.6571.0.0,0)

And the bug is fixed! The reason... I am not at liberty to show Intel ;-)

Hi thanks, yes I’m not tech savvy to to understand all those threads but Appreciate what you have suggested. Can I ask what you did? The installing sounds like that will be better in the long run than getting the additional Camera? And I just google that and follow how to? Thanks

Click on the Apple icon in the top left corner of your Mac screen. Then click on ‘About This Mac’. A window will appear that describes your MacBook. In the bottom right hand corner of the window, there is a ‘Software Update...’ button. Click that button and another Software Update window will pop up, checking if there are any updates for you MacBook. You should then be shown that the Catalina update is available for your computer, asking you if you want to install the update. If you choose to do so, you press the button and follow instructions.

MAKE SURE YOU ARE BACKED UP BEFORE INSTALLING THE UPDATE.

I gather that some folks have had some issues with Catalina. Certainly there are some old apps (like Aperture) that will no longer work. But I did the update and have had no difficulties. And no more camera crashes.

No as I need someone to help me. I used Skype instead with an client and it also crashed. I Would of I never brought Mac book pro knowing I would have issues. I need to find someone technical to assist me as I don’t know how

My MBP is also crashing in the same conditions:

MBP (15-inch, 2019), 2.3 GHz Intel Core i9, 16 GB 2400 MHz DDR4

Radeon Pro Vega 16 4 GB, Intel UHD Graphics 630 1536 MB

I am wondering if forcing the use of the Radeon or the Intel graphic card would make a change…
