Catalina 10.15.6 keeps crashing

After nothing else worked for me, Gravis (a German Apple retailer) replaced the main board of my 2020 MacBook Air.

The computer runs without and issue for two weeks now. No kernel panics / crashes / unexpected reboots.

They gave it back to me with 10.15.3 installed, and I don't dare to update the macOS because I'm afraid a newer version will break it again. I know, we're on 10.15.7 now, but I don't trust the peace (yet).

BTW: The MacBook also had cooling issues before the repair, causing the fan to run at high speed a lot. After they replaced the main board, this issue is solved as well. Maybe there was a connection…?

EtreCheck is on the Apple App Store. There is a charge to unlock its full capabilities but it's a legitimate and very helpful tool.

Maybe you are using VMware?

On my Mac mini, the situation is exactly the same.

I am waiting for VMware Fusion updates :-)

This is another Sleep/Crash pandemic going on around Catalina. You should contact Apple Support

I applied the supplemental update. Seems to be stable, no memory leaks. Running Virtualbox, Docker for Desktop.

I am also receiving dialog boxes asking me to re-enter/re-confirm my Apple ID. When this happens I usually have to force restart the iMac. The VMWare Fusion Community Forum has activity regarding MacOS 10.15.6 and VMWare Fusion. https://communities.vmware.com/thread/640143

MacRumors is posting information regarding VMWare Fusion and MacOS 10.15.6 as well: https://www.macrumors.com/2020/07/27/vmware-confirms-macos-virtualization-bug-causes-crashes/

Same here. Since the downgrade, a week ago, no problem. TimeMachine is great.

When I update the machine I usually take the chance and remove some used software. So first I though that was the reason. Some incomplete removed driver or so. Nope, removed them on 10.15.5, all fine.

Keep my fingers crossed that Apple will find the reason soon. That can be hard sometimes.

Until then I wait for 10.15.7. And, sad to say, start with what I do with these windows machines all the time: Wait a while before installing an update.

Curious @akashthomas43, I've been running the update on 2 systems for > 6 hours and neither have leaked any kernel memory that I can determine from watching the wired memory counter.

Perhaps you have a different problem. Watch the "wired memory" number in the memory tab of "Activity Monitor" to check whether it gradually grows over the space of an hour.

[edit: I'm running VirtualBox on both with different uses in the VM's, different disk & network configs. My MBP panicked during the install phase of the update but recovered and completed ok - it was a watchdog timeout in the SMC driver. Another person at work reported a panic during install.]

"macOS Catalina 10.15.6 Supplemental Update" released this afternoon. Hopefully it will fix at least some of the issues reported in this thread.

A bit offtopic (sorry!), but the size of that „supplemental update“ really surprised me: 2.82 GB for a mere bug fix. I remember when Mac OS X required 1.5 GB of disk space -- for the whole OS.

That aside, I guess we are all hoping for Catalina's different kernel panic issues to be resolved with that update. It seems to have successfully fixed the memory leak which affected VMWare users. But there is no evidence yet for the random panics that usually come late at night, and for the panic-on-wakeup issue.

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!

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.

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.

Malwarebytes is one app that is OK to have. I use it but don't have it running in the background. I run it only when I think I might have encountered some malware or adware.

To remove that file boot into Safe Mode (How to use safe mode on your Mac - Apple Support) by booting with the Shift key held down. This prevents any 3rd party software for activating.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing some system cache cleaning, volume verifying and directory repairing. 

Then run Find Any File to search for any files with the application's name  and the developer's name in the file name.  For example for the one file you want to remove you'd do the following search: 

1 - Name contains MB_MBAM_Protection

Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion.

FAF can search areas that Spotlight can't like invisible folders, system folders and packages.  

Have had no problems with it on my iMac. Post an Etrecheck report.
