kernel panic three times since upgrading to 10.14.6

Installed the update yesterday, restarted once in between, Mac was sleeping overnight. This morning had a 1hr Skype conversation using the integrated webcam, no issues at all. Let's see if it stays this way.

Same issue happening to me while video conferencing and screen sharing using either google meet or zoom.

I took it to Apple Support several times who changed the logic board one time, and did several hardware tests another time, but they keep saying that it's not a hardware issue. I switched from chrome to Firefox, as per Apple Support's instructions, with no luck. I switched from google meet to Zoom but it's still happening. I opened several cases with Apple Support to get it resolved with no luck.

It's very inconvenient especially when it happens during business meetings.

I thought of installing Ubuntu on it to avoid the issue, but I read in several articles that Ubuntu does not yet support this hardware.

Here is my hardware configurations:

MacBook Pro (15-inch, 2018)

2.6 GHz Intel Core i7

16 GB 2400 MHz DDR4

Intel UHD Graphics 630 1536 MB

They have my Laptop in the shop now. It's VERY displeasing. And another user above stated that they had their logic board replaced and it STILL happened. NEVER will I accept it's a software issue. Get it together Tim Cook and Apple.

Someone from Apple's support suggested me to install high sierra on an external hard drive (don't know how, can't even download previous OS from apple), and if the problem persists, I should take my MBP (15, 2019, base model) in again. If there's no problem with HS, I should wait for Catalina, beacuse there is where the devs time focus is at.

Catalina release is expected to be next month.

Same problem. I can recreate a panic by using video (multiple times per day). Sometimes it happens after a few minutes, sometimes after more like 45 minutes. I mainly use Sococo for video, but I've recreated the problem using either zoom, gotomeeting, or Cisco Webex.

Same problem.

When I'm on and video call, it's freeze and turning off after random period of time (up to 60 mins).

How to fix it?

I have MacBookPro15,1 2018, bought it 3 weeks ago (new)

Ah crap, it worked fine for almost two weeks. Now this morning it just crashed again two times after a couple minutes of Skypeing. Called Apple and let them know their stuff is still not working, and they told me that the engineers are still working on this particular issue. Back to using a USB webcam.

It just happened to me all day using Teams on latest build + supplemental update. 15inch/2018, 2.9Ghz, 32GB

Crashed three times during four conference calls.

Same crash dump and this is not a hardware issue. Latest build introduced this issue.

What's interesting is when I had it plugged into a multi-port hub at work (2 external displays, Ethernet, USB connections, External drive connections..etc) this problem wasn't happening during many video conference calls.

Apple needs to accelerate a fix here! Unacceptable on a $3k+ machine.

Does Apple have a fix for this yet? I reinstalled the MacOS and then it crashed again during a video teaching session on Thursday again. The computer gets hot and it only crashes when the camera is in use. The crashes aren't easily repeated. Sometimes it's one after another and other times I can go a couple of days between. I bought an external camera and am using that because my job depends on my not dropping clients. Has anyone actually had this fixed at the store? I don't want to bring my laptop in and not have it fixed. It is extremely difficult to go without my mac when I work from video at home. I am under warranty, but don't want to go in until they have a fix.

Hey guys,

Just like the 2018-004 Sleep Wake issue, I just last night wrote an article on the 10.14.6 FaceTime Camera crashing issue. Let me know if I am missing anything. Feel free to pass this along, if anyone is asking about the specific details on this issue.

Yet another user here with the same problem. 10.14.6 / MacBook Pro 2019 (15,1)

FaceTime, hangs, fans go super fast, shuts down.

Have reset SMC and NVRA, also repaired disk.

Issue carries on....

Only ever crashes in FaceTime, and only since 10.14.6

This issue is by now well known, affecting recent macs with a T2 chip.

A solution is also known. Install Catalina on a separate drive. You don’t even have to run Catalina. The installer does a firmware update that resolved the problem. If you don’t want to install the beta, the release version is due this month, probably very soon.

Same thing. My machine only crashes when doing Skype/FaceTime/Viber or any other video application. Never had any kernel panics before and it only started when I updated to macOS 10.14.6.

Get it three times during one video session (1.5h) using internal website in Chrome. Didn't get it during another 1.5h session earlier today. Never seen any crashes on this MacBook Pro at all.
