Kernel panic sleep Catalina 15.4

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

To be sure - this is a know issue with 15.4, it's a SOFTWARE issue and it's in Apple's bug tracker. Don't send your system back, simply disable Power Nap and you are fine. While 15.5 beta 1 doesn't fix it yet, I assume it may be addressed as soon as beta 2 (and then the GM).

Barney,
Essentially the point is other users are also facing this issue. and since I have been able to reproduce same in safe mode its to do with Apple kernel files. Plus 15.4 just came out 4 days back. so there might be other users facing same issue as well.

Till date there seems to be no solution other then reboot and save all work before every sleep

I'm not experiencing any problems and have been running .4 for several months on two very different Macs. I am currently running the .4 release without issues.

I haven't seen any other long-time posters report of problems, nor do I remember seeing anything noted by anyone else in the rumor mills (but, I don't pay much attention to them anymore).


The point is, if you want help with your specific problem, you have to create your own post to focus on your problems specifically.

Please understand:


You were asked to sign/accept a non-disclosure agreement when signing up for the beta program. Read the following to find out how you get help as a seed test participant:


     CUSTOMER SEED AND CONFIDENTIALITY AGREEMENT

   Apple Beta Software Program


The NDA prohibits you from discussing software beta issues here or anywhere else. The two documents above describe how to submit problem reports to Apple.


Do not use the Apple Support Community forums to discuss Apple's beta software nor to post bug reports.

Hi,

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
https://www.ibiblio.org/harris/500milemail.html

I have no idea what any of that has to do with this problem.
