MacBook Pro 2017 15" kernel panic after going to sleep

Whenever my Mac goes to sleep it crashes with a kernel panic (when I press the power button I am greeted with a message along the lines of "your mac has restarted after a serious problem" or something to that extent.


After a successful boot I see the panic report which always is the same and begins with the lines:


panic(cpu 0 caller 0xffffff7f8b739fcd): "Failed to quiesce supporting devices\n"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/AppleACPIPlatform/AppleACPIPlatform-281.70.3/AppleACPIPlatformPower.cpp:1970

The rest of the Panic Report can of course be supplied if required.


The Mac runs macOS High Sierra and I have tried:

  • Disk first aid
  • Reinstall macOS
  • Reset the SMC


but to no avail. Every time the Mac goes to sleep, it kernel panics.


The problems came after I installed the latest security fix from Apple on July 10: Security update 2019-004 (beta for developers) and developer preview of Safari version 13.0, seed 2.

Hey Guys,


I am following this issue and looks to be only affecting T1 and T2 equipped Macs.


That includes

  • 2017 iMac Pro
  • 2018 Mac Mini
  • 2018-2019 Macbook Air
  • 2016-2019 MacBook Pro with Touch Bar.



Anyone that installed the update can you check something? I want to see if the Security Update installer created a tmutil 24 hour snapshot.


Run this command to check


tmutil listlocalsnapshots /


You should have a listing from the past 24 hours. If you do you can boot into the Recovery Partition and restore to this snapshot before the update was installed.


I am following this issue and updating when I find new info here.

Hi sfoiphone -


When you were told that the mainboard needed to be replaced at the Apple Store, was this covered by AppleCare, warranty, etc.? I ask because I bought my 2017 MBP 2nd-hand and don't have AppleCare to cover the cost of a repair like that (that one can't be cheap - I've read somewhere in the range of 3/4 the cost of the entire laptop). It's 2019 so I'm a year past the 1-Year warranty but I really feel like Apple should be covering this one, considering the high number of reports of this exact same issue across this site and many others.


Glad you were able to get your machine fixed. I appreciate the info!

Same. Unfortunately I upgraded to High Sierra hoping to fixate problem, it didn't, and I ended up with a piece of software that is no longer usable in this OS. So bad on Apple all around, especially the lack of communication. Wouldn't have known about the update without this forum and it makes you wonder how many people are both gun-shy now AND not following the issue here. Bad communication followed a bad update.

Hi Guys

I had the same thing, only worse. I installed the security update and my 2013 iMac crashed during the process.

Upon reboot the screen no longer works. All I get is a black screen.

I used a lightning to AVG adaptor to plug into a Sony TV screen and was able to boot up.

I tried resetting SMC and PVram to no avail.

Took it into an Apple authorised repair after speaking to Apple Support. The result is that the screen is now officially declared dead! Apple say I must pay for a new screen!

This is madness. How can they release an update that effectively renders my iMac unusable without an external display and not take any responsibility?


Im trying to escalate this through Apple support at the moment.
