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

I've had exactly the same experience, close the lid and put on charge at night and when I open the machine up in the morning, the machine has rebooted with a panic in AppleIntelFramebuffer::setPowerState.


By unchecking "Enable Power Nap while plugged into the power adaptor" in System Preferences > Energy Saver > Power Adapter as suggested in this thread, I've had three trouble free mornings.


Thanks all and awaiting a fix from Apple.

Same here. ( 16"/i5/32/512) Had this reboot twice this week. In both cases it was left with lid closed. Plugged in.

Never had it before 10.15.4


Just disabled Power Nap and flipped Automatic Graphic Switching ( turned it off and back on )

Will post if I have any more reboots.


Apple, please fix! There is been at least seven new threads about this issue recently.

For me, disabling power nap fixed the issue completely (16"-MB Pro 2019), no more shutdowns since 5 days.


@Step89: Do you have that since the update? I suggest you to check for third party kernel extensions (in terminal: kextstat | grep -v com.apple). You could also try to unplug the power and all devices and check if the crash still occurs. Good luck!

I bought a brand-new MacBook Pro 16' three weeks ago and it crashes from the first day 5-10 times a day. I am so desperate. Even the latest update of MacOS provided today does not solve the problem. I cannot believe that Apple is pushing products like this to the market. I am simply not able to work with this product. Its the worst an most unstable system I have experienced ever.

By the way, I tried everything from a clean installation of macOS Catalina to all the kinds of reset mentioned before.

Apple help me or I will refund the product very soon and get myself a stable Windows 10 device.

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?!
