Apple Intelligence is now available on iPhone, iPad, and Mac!
Hi,
Ever since upgrading to Catalina 15.4 4 days back. Getting a sleep kernel panic. System restarts evertime I wake it from sleep.
Its to the level I am afraid of putting it to sleep any longer.
I am on 16" Macbook pro, and using since 3 months and Issue never came before 15.4 update
Check the logs below -
MacBook Pro
You have a ton of third-party extensions installed any one of which could be causing the problem. The panic log suggests that it started in the video drivers. Boot the computer into Safe Mode and see if the panics continue.

Kernel panics are indicative of possible hardware failure, so you should Check your Mac with hardware diagnostics or AHT. Kernel panic logs are found in: /Library/Logs/DiagnosticReports/ folder.
If you have no success figuring what is happening then you may need to examine the software you have running when the panics occur. Be sure it’s all current. If you must to resolve the problem erase the disk and reinstall macOS. Follow this outline to reset the computer to the factory-new state: Factory reset of your Mac - Apple Support.
Boot Into Safe Mode
I consistently saw the kernel panic in sleep on a brandnew Macbook Pro 16, i9, 5500M 8GB with a clean 10.15.4. with only apple power supply connected. As I didn't start to work productively on the new machine yet after I experienced the problem I didn't see other effects so far. The kernel panic in sleep could be avoided on my machine by disabling power nap as a work around.
How did you "disable Intel graphics kernel"?
Its helpful to know someone with same the machine is experiencing the same issues.
My issue now is whether to tough it out or just send the machine back. Never know could be something more sinister. Not likely but im covered for the next 12 days.
Such a frustration on a new machine when need to just get on with work.
I had a call from apple support they are working to resolve the issue.
In meantime you can check which third party Kext files you have loaded and disable them.
Go to Library/extensions and delete third party kext one by one to shortlist which one is causing the issue.
make a backup so that you can restore them later
Thanks for letting us know.
Good to hear they are aware of the problem now. My experience with apple support was rather disappointing, they didn't seem too much interested.
In my case (MBP 16, i9, 5500M) with clean 10.15.4 only disabling power nap helped. Disabling the graphic switch to built in intel graphics didn't help.
Well the few day old machine ive just formatted to give it another chance before sending back.
Loaded it up first time stepped away for a little bit and its crashed and restarted. Shocking from a £4k rig.
All that was open was one Safari tab with BBC homepage.
Sending it back until they fix the issue full stop. Worst experience ive had buying a machine. Need this for work and always went Apple for work. They are seriously burning bridges with their core base here.
I understand you are upset, and you have a right to be upset. But your approach is like throwing out the baby with the bath water. There is no such animal as a perfect electronic device where millions are made, and they all work perfectly forever. There will always be defective machines, and someone will buy them. This was just your time in the barrel, if you get what I mean.
Had 3 macs now. 2 dud macbook pros. The other was a 2012 from new from apple. Constantly firing up fan running a max. Took to genius plenty times. Even amazed that one time it wore the bearings on the fan to create a rather unique noise. Was like a set of star wars jawas in owe gathering around it as they had never known anything like it. They never resolved it and eventually died on me. I give Apple plenty chances but their hit rate at faults is pretty poor from my pov. Can only go from my experience.
Some replies from “Gurus” with 10,000 points+ are exactly why I haven't been here in two years until i read about this issue on Cult Of Mac... My system is working fine currently.. but in the past when it hasn't, I asked for help here. All I got in return were sarcastic, snide remarks & condescending replies from Top Points Members. Some were like, “Well no one forced you to upgrade, or nothing is perfect, or you need to retire that Mid-2012 MacBook Pro and purchase new hardware. I got sick of it and all of the Omnipotent Old curmudgeons here who wouldn't dare talk like that to a younger man's face. So good luck I'm sure this problem will be addressed soon enough by the truly good Apple Professionals in Cupertino. Save your time and aggravation and stay away from these so-called community support forums.. they're almost as bad as some Facebook Groups. Perhaps I'll be back in another two years and see if anything's changed. ~RpH
Simple thing is you buy a machine for it to work. You need it for work. You buy the best. This clearly is a bigger problem than an odd case.
I've formatted the machine multiple times. Done tests. Done changes to settings. I've given it plenty chance and not thrown my toys out pram. As nice and sorry as they were, customer support didn't really have any idea what to say but in the end return it. Really nice about it mind and no ones fault. But apple are now releasing things to meet sales dates for shareholders than what it's right by their core user base. These OS updates are too often that they can't check QA properly.
This is constructive feedback not yours throwing out the pram. I rarely moan thank you very much and deal with customer services daily with my business.
@ Barney,
Do you see why you should not take these issues as rumors. I was among some of the first people to report it. However its all over now.
I read a very interesting article on "unable to send emails over distance over 500 miles" Should read
I have a user who is experiencing this same issue.
Macbook Pro 16", i9, 32 GB RAM, connected to external HDMI display using Apple HDMI/USB/Thunderbolt adapter, macOS 10.15.4
When the computer resumes from sleep, we encounter the kernel panic error.
Sleeping duration could be a short time (~45 min), or overnight.
Examining the system.log for the overnight crash, the last entries before the crash pertain to
adobe_licensing_helper[5592]
com.apple.xpc.launchd[1] (com.apple.DumpGPURestart)
I see some suggestions here:
Disable Power Nap (System Preferences)
Disabling the Intel Graphics Kernel (Is there a safe and easy way to do this? Would it cause issues with future macOS updates?)
Does disabling system sleep mode help? Or is the issue when the display enters sleep mode?
Thank you for any advice or guidance.

I have no idea what any of that has to do with this problem.
I have only faced the issue after long duration of sleep (Mainly overnight) almost never with short duration of sleep.
Disabling Power nap is definetely working, Intel graphics is a third party graphics energy kernel. just make a backup and delete it from library/extensions. and flush saved status.
Disabling deep sleep also helps, but your getting same result by disabling power nap. Does not happen when display enters sleep mode. System should go in deep sleep.
I am having the same issue on my two-week old 16" MacBook Pro. The machine is crashing after waking up, creating a crash report just like yours. After reading dozens of articles on this issue, I have come to the conclusion that the machine is crashing when switching from graphics card to the other; thus, the issue is caused by the current firmware, Catalina v. 10.15.4. My old 13 inch MacBook Pro with a single GPU is running the same firmware and it is not having any issues.
I have tried everything to try to solve the issue including erasing hard drive and installing MacOS from scratch, nothing has solved the issue. Apple needs to release a fix ASAP.
I had the exact same issue, brand new MBP 16 inch with upgraded graphics card. Sent it back for a full replacement and after it going to sleep for a few hours (plugged in) SAME EXACT PROBLEM again!
This is ridiculous, sorry I don't have an answer, but I feel your pain. I totally disagree this is an issue with 3rd party apps or extensions because with the original machine I had, I wiped it clean and still had the problems.
