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

After I I've updated to the latest release of macOS, I've experienced a weird bug every time I leave my laptop closed (still on) for more than a couple hours and plugged in.


It reboots and states the message/log below.


Not sure what they changed but this did NOT happen before the update.


Things I've tried:

  • SMC Reset
  • PRAM Reset
  • Soft Reset
  • Hard Reset


I still experience this issue everyday.

MacBook Pro 16", macOS 10.15

Thank you all for the support and suggestions/work arounds.


For my MacBook Pro, turning off the Power Nap feature on ONLY the Power Adapter setting has worked for me so far. I can leave that feature on when using the Battery.



As a side note, the latest supplemental update for 10.15.4 does NOT fix this issue yet. I have tried the BETA and can confirm they are working on fixing this bug because I did not experience a kernel panic when using it.


Now that said, I do NOT recommend the beta version. When we use betas, we run into beta bugs. There are quite a few that would annoy anyone using it which is why I've reverted back to 10.15.4.


So here's to hoping Apple can push 10.15.5 soon without any new bugs. <----- I know that's probably impossible but here's to hoping right?!

After leaving laptop for some time (mostly lid closed, but sometimes lid open asleep with and without external display), it has been rebooted and shows the kernel panic form to submit to Apple. Only happening after update to

Where did you read about this bug in news portals?

Maybe Apple engineering is aware of it already, it's just the support team which isn't. Could well be. Apple support told me if it's power Nap he doesn't consider it a serious problem, not many people would consider it important anyhow. Well, personally, I think it's useful if the macbook wakes from sleep when powered, e.g. to do Time Machine backups to my ancient time capsule that it didn't do yet while on battery.

On the other hand: if this exact problem is in official news already we may consider saving our own time ...

I have the same issue. Just got a new 16" MacBook Pro. When plugged in over night at some time it restarts. Same error every time.

this doesn't work with my MacBook Pro 2014. I write this as I open the lid, send the error report after restart and first thing sign on here to see if anyone has a fix. Catalina is **** poor piece of software. It ought to be able to restore to older system without having to wipe drive - but that is the next thing to do, to get back to stable OS.

Wish I could run Windows on this laptop...so fed up.
