Catalina 10.15.6 keeps crashing

I have a problem. I updated to macOS 10.15.6 and now my system keeps crashing when I leave my computer for some time. Here is the crash report (some data removed for privacy concerns)

panic(cpu 2 caller ): userspace watchdog timeout: remoted connection watchdog expired, no updates from remoted monitoring thread in 69 seconds, 2219 checkins from thread since monitoring enabled 44430 seconds ago after loadservice: com.apple.logd, total successful checkins since load (44430 seconds ago): 4443, last successful checkin: 10 seconds ago

Any idea what I can do? Please help, my system is unusable. I cannot restore my workspace every few hours when I leave my computer unattended.

As I said in my previous post, Windows 10 is the answer. I have a brand new Macbook Pro, the most expensive laptop I've ever owned. But I also own a couple of other laptops that run Windows 10 which are several years old and none of them ever crashed, not even once in all those years. What I'm doing now is completely wiping my MacBook Pro and installing Windows 10 on it. I have been running Windows 10 on one partition with bootcamp and that never had a problem. The crashes only occur on the Mac side, which proves it's not a hardware issue but has something to do with the utter incapability of the Apple developers to produce a flawless operating system. While I still like the Apple Hardware, the software is an absolutely catastrophe. My recommendation to the Apple developers: go and take an internship at Microsoft and learn how to do stuff right!

People in this discussion are looking for help to solve a specific technical issue in macOS.

“Get Windows” is no solution, your comment is far from helpful, and it might easily be considered as trolling.

This is a macOS forum. People here are looking for macOS specific help and information. Your ranting on and on and on about Windows 10 is of no help whatsoever. You are in the wrong forum. Continuing your rants is simply trolling.

Updated to 10.15.6 Supplemental and my kernel panics have stopped. I have some other somewhat unusual behavior such as a lot of fan activity and the fact that my iMac monitor will not go into “off” mode no matter what the power saving settings are. Other than that the supplemental has handled the major issue and I am hoping that Big Sur will take care of the other odd behaviors. I am running both VMWare Fusion and Parallels 16.

Regarding your Mac not going "off", which I assume you mean sleeping. Try running Activity Monitor, then in the CPU tab enable the column "Preventing Sleep" and sort on that column. That might give you some clues.

Actually the monitor of my iMac no longer shuts off after the elapsed time. I have unchecked the wake on LAN setting. The screen saver kicks in as expected it is just the monitor that does not time out and turn off. I will check out the “Preventing Sleep” section of Activity Monitor as you suggested. Thank you for your response.

Okay, I agree to what you and others have said and I will stop ranting. But I am just extremely frustrated that I can't find a solution to my Kernel Panic issues. I even spent a long time with Apple support on the phone and they had me reinstall my entire operating system. But the issues just came back. But I agree with what you say, that just letting off steam doesn't help anyone. So no worries, I'll keep my mouth shut for now and just hope the OS issues get fixed some time soon.

As there are at least three different kinds of kernel-panic related problems discussed in this thread, it might me a good idea to always specify which of these problems you have or had:

1. A memory leak that leads to reproducible freezes/crashes/kernel panics especially when certain VM software is used.

--> The Supplemental Update should have fixed this.

2. An issue that causes random kernel panics, even when no apps are running and the Mac is on idle (often late at night).

--> The Supplemental Update seems not to have fixed this.

3. Crashes on wake up after system sleep.

-->The Supplemental Update seems not to have fixed this.

Very helpful summary. I am going to apple’s flagship store this week with my macbook. I’ll update anything that they have to say. Hopefully since it’s Apple’s main store, they’ll be able to provide some help to this.

After installing the supplemental update 13.15.6 no problems until now: in mail no text of the e-mails, closed mail and tried to open Firefox and the system crashed. My iMac (late 2012) would not restart and a hard restart was the only option. So instead of a crash every three or four days, it is now a crash after 7 days. :-(

I have Microsoft Office... however, I think the culprit is more likely to be my external disk drives - 5 in a caddy. When they were disconnected my iMac did not crash at all. Initially I thought it was a thunderbolt connection issue, and moving to a USB connection seemed to make the crashes less frequent, but they still happened. The exception was for the 24 hours or so that I left one disk connected and copied the data to a NAS - no crash while the disk was active.

I do not have Microsoft Office or Adobe Creative Cloud but am experiencing the kernel panic/ crash and reboot when using sleep mode. I have had this problem on 2 different brand new iMacs with very little software installed.

I upgraded to catalina 10.5.6 last week and my MacBook Air crashed this morning. I restarted it and was prompted to do a macOS Catalina 10.5.6 Supplemental Update, which I am currently in the process of downloading. I will not be happy if my Mac crashes after this update.

updated my MacBook 16 pro - got this in June. updated to this maybe earlier this week. now when unattended for perhaps 30 mins or so, it restarts due to an issue but no app would be running. Now my TouchBar is completely off - it does not even recognize i have a touchbar in my system preferences.

so i factory reset the Mac and boom issue fixed.

but same thing happened - Crashed - Restarted due to an issue - and TouchBar once again OFF - no way around it. this update really caused it.

excuse the bad grammar - i am just frustrated. got an appointment for service nearby and at authorized dealer since apple stores are closed right now in LA Area. i really just think its this Update. really did a number here.

I had the same exact word for word issue. I brought it into apple, and my laptop, the 13 inch 2017 model is still under the keyboard replacement program, so they replaced my Touch Bar for me under that warranty, and it just came back, in perfect condition. So far the Touch Bar is working and my sleep is functioning as well. So I genuinely believe that the issue is a Touch Bar/Keyboard issue if everyone else is having this occur with their Touch Bar MacBook. It makes sense because the Touch Bar is always functioning, so it could have something to do with the kernel and that maybe.
