MacBook Pro 16 2019 10.15.4 Kernel Panic / Reboot When Plugged In -- Help!

I also gave up and returned my 16” MacBook because it wouldn’t get past the login page. I am thinking of rebuying the 16” or a new version of MacBook Pro once the issue gets resolved

I am also currently working on my 2014 MacBook Pro for the time being and it’s pretty slow

@10_Gauge is one of the lucky ones ..

I used my 13" i5/8gb/256gb today for 2 location photoshoots, came back home Airdropped the 2 Capture one Session folders to this 16in i9/64gb/1TB/8gb5500M, left the computer for about 30 minutes and came back ... When i opened the first session The 1tab Youtube music that was playing started twitching, squeeking, everything froze and music just kept skipping, till the fans when full speed for 1 sec and macbook turned off . This is the error .

This computer is unreliable if you are working next to clients . It will embarasse you at least 1x a day .

Meanwhile senior costumer support Anna didnt accept my 14day return thinking i was the issue .

Might put an ad up and sell it for 3500 after paying 4300 for it.

back in 2018 i had a 2017 i7 16gb 15in macbook was so solid quit, ran low temperature with multiple apps open + 4k screen. This one goes up to 75c just for plugging my 4k monitor. Apple needs to admit they shouldnt have put i9s on these machines.

I also have the issue of the original thread question and I have Catalina 10.15.5. Not sure if they just haven't fixed the problem but my 2019 MacBook Pro 16" constantly turns off every time my computer goes to sleep even for a little bit.

Same here. My computer says up to date ... some week it behaves and i only get 3 or 4 panics, some weeks it doesnt i get 3 a day . So yeah. It is not fixed yet .

I noticed that it panic less if i dont unplug it .

Ah, @techitype. Sorry to hear that. Your issue seems to be the "connected to external monitor" version of this issue. I don't have an external monitor. Mine seems to be working fine. I hope they address it (because what if I want an external monitor one day!!?)

Hey there sorry for being blunt! But maybe you should read the entire thread!! It has nothing to do with 3rd party apps. I had this out of the box no external monitor connected and no 3rd party apps installed! Like many have tested it here. Apple needs to hurry up and fix this iso waiting for their new new OS to roll out!

Huh, maybe it's time to reach out for Macrumors, or some other media and ask for a post in their blog. Looks like Apple kind of ignores the issue. There must have been some "quiet" updates, that did fix it for Some users ( like me ). Bit apparently - the issue is still there for a lot of folks.

I think I'm experiencing something very similar with my brand new 2020 13" MacBook Pro, running macOS 10.15.6.

I have an Apple 27" Thunderbolt Display (which I still really like and don't want to upgrade) which is plugged-in to a Belkin Thunderbolt 3 Express Dock HD via the Apple USB C to Thunderbolt adapter. My new MBP is then connected via a single Thunderbolt 3 cable to the Belkin dock. Everything worked perfectly with my old work 2017 MBP (apart from the keyboard, of course) but since I got this new 2020 model for personal use, it is impossible to connect and disconnect the cable from the dock to the MBP without the MBP having a kernel panic.

Apple Hardware Test finds no issues with the new machine and macOS appears to be working fine in standalone mode (as a laptop). The issues start as soon as I attempt to use the MBP in clamshell mode, connected to my Apple 27" Thunderbolt Display.

What normal seems to happen is this:

1. I plug the sleeping MBP into the Belkin dock via the Thunderbolt 3 cable
2. The desktop is visible, momentarily, on the Apple 27" Thunderbolt Display
3. The display then flashes a few times
4. Then it goes dead

If I then disconnect the Thunderbolt 3 cable, and open the lid of the MBP, everything appears to be frozen. The fans spin-up for a brief second and the screen goes blank.

When I press the power button on the MBP, I then see the multiple language "Your Mac shut down because of a problem" black screen of death. Once the Mac reboots successfully, I then see the error reporting screen:

https://support.apple.com/en-gb/HT200553

Obviously, I report this to Apple every time it happens.

I'm fairly confident this is not an issue with the Thunderbolt Display or the Belkin dock since both worked flawlessly a couple of weeks ago with the old 2017 MBP. I believe the issue is with this new 2020 13" MBP I just bought. I guess I could try bypassing the dock and plug the USB C adapter directly into the MBP.

I've tried turning off the well-documented "power nap" options in Energy Saver preferences but this does nothing to help my situation.

Does anybody else have any ideas what might be going on here, please?

Thanks,

Steve

10.15.6 installed with power nap on, both in batt and on charging. Switched those on after installing 10.15.6 a week or two ago. No KP until today. Opened up my MBP and there was one again.

Apple this is below your standards. FIX ths F....... Problem!

What are we doing about this guys ? My computer is supper unrealiable . Can really close the lid, unplug move to another room and open it back up and hope it will come out of sleep . Do we have info if its all i9 MBP 16Inch, or if it only happens in some of them ? Is this a hardware problem or what ?

Then it can be random thing. I firstly bought 64gb(1tb ssd) and refunded. And secondly bought 32gb(512gb ssd) and it works fine now. (Both are 2.4ghz, 5500m 8gb)

I thought it was because of RAM size but I was wrong.

1. described in detail every step I took (reset PRAM, SMC, wiped drive twice and reinstalled OS, disk diagnostics, hardware diagnostics)
2. had a log of every kernel panic my machine had since March (at least 1 per day)
3. refused to ship it off for severals reasons (I am a developer and can't be without the machine, didn't want to have my machine be the experimental machine for the Apple engineers to tear apart and try to uncover the issue.)
4. shared the amount of $$$ I've spent with Apple over the years (multiple iPads, watches, iPhones, laptops, etc.)
5. insisted that the problems were caused by 10.15.4 and insisted that my machine wasn't a "one-off" because of threads like this one (and the Mr. McIntosh thread)
6. promised to send a very detailed email to Tim Cook. I've successfully emailed CEOs in the past - not for trivial issues - only for issues that I repeatedly tried to have corrected by the service teams.
7. I wasn't rude or angry - just insistent that Apple should take accountability for putting the wrong type of gas in my car causing the engine to fail. My MBP was sweet until 10.15.4 - everything was a mess after 10.15.4.

Thanks for sharing Tim. After several calls with senior Apple engineers and wiping my drives, I'm being sent to the Genius bar. So it's good to know about the logic board and Touch ID - I'll mention this when I go.

Like you say, it would be great if Apple were honest about this, with so many people having issues with the new MBP 16".

Enjoy your working MBP!

Thanks for this post. i bought mine about 6mo ago, and i just barely ise ot for important atuff. Only use it when im alone and no clients around, because i know how unreliable this 4500 dollar machine is. This is a replacement to my 15inch macbook so i went thru so many calls and logic board on my 15inch one that when it got replaced and i got this worst computer that was supposed to be better i just settled and have been jist hiding it from anyone who it would embaresse me with the qeird hickups i get from it. 98% of the times ita just the sleep awake panic, but from time to time mine just straight up turns off out od no where .. lol(laughing so i wont cry) ... Anyway in 2 weeks i ll have to have a powerful laptop on set and i ll have to use this ... Whats a genius bar? I need to get mine fixed, should i jiat start calling apple right now and ask them to ssnd the box so i can send my computer and thats what the genius bar is?

I really need to get thos mbp fixed in the next 2 weeks

I've the same model and experiencing the same kernel panics while laptop is sleeping
