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

This is beyond shocking that apple has not resolved this issue on what should be their very best laptop....I am astounded that the update is taking so long to come out and we are suffering day in and day out ,sometimes over 10 times in one day .

I will try to disable the power nap and give feedback in a few days time.I hope a class-action is on the cards for us affected buyers.

This is the next staingate it seems!

What a Shame......

I took a 3 year hiatus from Mac computers and built some PC gaming rigs. All run well but the one with the AMD GPU gives me a bit of an adventure because AMD is horrific with driver updates. But that was an AMD issue, not Windows proper.

I have a $600 HP pavilion laptop that trucks along. Never a blue screen of death.

So it’s very disappointing to come back to Mac and see how the quality of Mac OS has sort of fallen off. Not only has it felt as if it’s lost a few MPH off its fastball, it’s also become very “bureaucratic“ in how it runs. Changing simple settings caused Mac OS to throw up signs saying I can’t do that. And if I want to, I have to do this or that first. Sometimes multiple steps. Then I could return and change the setting. Has the department of motor vehicles taken over? It was never like this before. The simplicity and rock solid reliability isn’t there like it was when I left.

Anyway, this MacBook I purchased still has a lot of upside potential so I’m optimistic that these sorts of things will get fixed. It’s a such a beautiful machine. Can’t say the same for Catalina.

Looks like the next version 10.15.5 fixes this issue. So, Apple does know about it but they don't care to admit it or don't advise their tech support (that's so frustrating but that's so Apple). So, you can wait, or go ahead and install the beta (now in the fifth version).

I have 10.15.4, which fixes the problem. Yes, it’s still in beta, but seems very stable. For me it was worth it to now have my computer reboot 2-3 times per day (even with an SSD, you can corrupt a file). All that being said, usually betas don’t go past 5 or 6 so probably soon...

I got my new 2020 16" Mac today. I have the same issue. I had nothing installed on the Mac except MS office. I just updated to 10.15.5 a few minutes ago. Hopefully this expensive device doesn't continue to crash with kernel panics. Crazy - went out and got the 32GB RAM / 2 TB SSD i9 model with the upgraded video. Ill know more tomorrow, but I thought I would post too so that Apple will acknowledge Houston there is a problem.

Please try to disable Power Nap (pluged in and batteries) in the power save options.

It works for many of us.

Actually it still works when you enable the Power Nap again afterwards. It seems to be the disable/enable that correct a wrong setting on the NVRAM.

My story: got my MacBook Pro 16” in start april. Upgraded to 10.15.4. Every time it went to sleep it crashed. Solved the problem with the power nap thing. Did not have any problems for 7 weeks. Upgradede to 10.15.5. Problem started again. Did the disable/enable power nap again and the problem went away.

I have reported this “fix” to Apple.

I've experienced the same problem with my 16" MBP on 10.15.5 and even the latest 10.15.5 patch doesn't solve it. Disabling power nap I still experience kernel panics often (weekly), esp in times of high graphics usage like during a video call or streaming video. I have called applecare 8+ times, sent my machine in for evaluation and they sent it back claiming "no problem was found". Apple has been unable to fix it unfortunately and censors my posts on this forum for "non-constructive rants or complaints".

Did everybody just also kind of gave up on their 16" Macbook like i did ?

This thread is quiet and my computer only got worst with the updates . Doesnt matter what i turn off on power settings.

Did you guys have a solid 100% work around for this. I can turn anything off, i dont care i just wanna be able to close my macbook's lid and open it and be able to continue working from where i left .

Rant; As on my first reply to this thread that got deleted a senior advisor from apple because this macbook 16inch was a replacement for my 2019 15inch macbook she did NOT let me return this computer and transfered me to costumer relation department where they denied me return with the the 14 days, and i pretty much have an unreliable computer that i find my self using my 13inch macbook pro i5/8gb/256ssd over this i9/64gb/1tb/5500M . This is unbelievable . I got so much money tied to this computer and for having had my 15inch replaced apple is gonna think i am the problem not their computers, but really, i just dont use this could be good computer. Im using a greased up 13inch i5 macbook over this .

Mine started working flawlessly after a combination of disabling and re-enabling Powernap, clearing the SMC, and updating to 10.15.5. I haven’t had a single issue with my machine in over a month now. Knock on wood and fingers crossed.

I hope you get yours sorted out as well.

Oh and I’m connected 99% of the time to a CalDigit TS3+ Thunderbolt 3 dock with 4 USB-A peripherals and a DisplayPort connected 27” 4K Dell Display.

Had the exact same issue. Returned my laptop and exchanged for a new one at a different Best Buy location. The problem has gone away. The manufacture date of my machine is: 9/21/2020 (from coconutBattery). I wonder if there is a pattern for manufacture dates and this problem?

Have you tried uninstalling VirtualBox?

There is an uninstaller on the installation dmg.

They do not. Using feedback form is I think one of the ways to let them know it's a mass problem:

Do you have it disabled on both power and batteries? You have to do both.

Yes.

Uninstall Parallels following the developer instructions. Check to see if you still get panics. If you do, and the log doesn't show parallels in the "loaded kexts:", then return it.

This website says that reports of 1.15.5 Beta 4 fixes the issue
