Kernel Panic after upgrade to 10.15.1

I have not tried yet but will do.

From my side I deactivated the Norton 360 firewall functions and I had no kernel panic anymore for few days now. I will try the powerNap with the firewall and be back

Regards

So I tried the PowerNap OFF/HD Sleep OFF while reactivating my firewall functions. I had again a kernel panic after about 30 minutes. Much later than before but the problem is still there. So I deactivated again the firewall.

Looking forward 10.15.2....or a new build of Norton

Regards

Just to reiterate, updating to the beta 2 of 10.15.2 solved my problem completely, am now into the 3rd day without a panic. iMac 27" with OWC Thunderbay 4 with 4 hard drives and a display attached to it.

Norton released a new build today. The problem of kernel panic disappeared for me having of functions of Norton active and PowerNap ON/HD Sleep ON.

No spinning wheel anymore that was appearing sometimes

My 2015 27" iMac routinely has the Kernal panic in the morning after doing "whatever it does" at night. No (obvious) crashes or restarts during regular use. The only thing I have connected to it is a USB 3 Time Machine drive. I'm not running any Thunderbolt devices or any Norton products--that I'm aware of. I do not nave power nap enabled--only Put Hard Disks to Sleep When Possible.

Same here, since upgrade to Catalina just a few weeks ago my MBP is crashing at least once a day. I have no external devices or any peripherals attached, just the Mac itself.

On Mojave I had no issues.

I suffered through this for several days. Catalina is just not ready for prime time and is a mess. Called apple support and after the usual stuff , start in safe mode, reset stuff.. the bottom line was to uninstall catalina. Very annoying.

While I was at it I ended up doing a dual boot and reinstalled mojave on one partition and windows 10 on another. Windows 10 is a far more superior OS and I never had crash problem like I had with Catalina. Will use mojave when I need to use facetime etc for apple ecosystem of apps and know that can bank on windows then macOS crashes.

:). well you read most of it. Anyways my intent was not to kickoff a Mac vs windows conversation, I use both OS. It is just that catalina has been a horrible operating system and windows latest is rock solid. I wanted folks to have the guidance for alternatives. Nothing against any of the companies, I don't own either of them, just need a stable OS.

Just upgraded to 10.15.2 and see they failed to fix the problem.

Can't let my Mac Mini go to sleep anymore, have to turn sleep off else it reboots EVERY SINGLE TIME, even after a few minutes of sleep.

Tried everything: Power Nap off, HDD sleep off, Network Access off, disable hibernation, deleted hibernation file, turned hibernation back on, SMC reset ... as long as sleep or hibernation is enabled it reboots when going to sleep/into hibernation.

And can't do an NVRAM reset by the way, not even by connecting the Apple keyboard with a cable.

Only thing that seems to help is unplugging everything Thunderbolt but that leaves me with no external data disk, no backup disks and no display-port, only HDMI possible but then I have no HDMI to the TV. I can't remember to read in their marketing you have Thuunderbolt 3 but shouldn't use it.

Calling support is useless as well, you get a genius that only knows two words: "clean install". I fixed five problems myself they recommended clean install for and don't have time to reinstall my computer on a weekly basis.

MacOS Vista is what they should have called it.

No luck here - with 10.15.2. iMac 27" late 2015 still crashes. The only workaround: Disable bluetooth and don't go to sleep mode.

By the way: I've installed macOS Mojave on an external disk - it runs without any problems. I think I manually transfer all data and programs to Mojave and then stay with 10.14.

Sleep panic is still happening for me with 10.15.2.

Since this thread started, I’ve bought a 16-inch MacBook Pro, and it also panics on sleep with my Thunderbolt 2 drive enclosure connected via a Thunderbolt 3 to Thunderbolt 2 adapter.

It’s a Mobius Pro 5C five drive enclosure, with five 4TB Toshiba drives concatenated into a single volume via JBOD. I’ve tried both APFS and macOS extended journaled formatting with sleep panics in either case.

So no Magic trackpad, Magic Keypad or Apple Airbuds can be used with Catalina in your case.

Here it's only disabling sleep (hibernate or not, doesn't matter) that needs to be turned off.

By the way, in pmset, does anybody know what "highstandbythreshold" is for? Mine is set to 50.

And whats the difference between sleep, standby and autopoweroff in pmset?

Experimenting a little further:

sudo pmset -a autopoweroff 0 (autopoweroff disabled for AC, battery and UPS)

sudo pmset -u autopoweroff 1 (re-enabled for UPS)

Now I can leave sleep on (prevent computer for going to sleep = off) but I do have to turn off bluetooth.

Or I can enable bluetooth but prevent sleep on.

I have the same problem. Mojave without problem and catalina ... !! Both versions 10.15.1 and 10.15.2 are still "kernel panic". really terrible as windows ... i don't have any ext. device in thunderbolt connector, installed only FCPX and only problems with device restart .... DO NOT UPDATE until Apple wakes up ..!

I do not understand, but I am currently calm ... I uninstalled FCPX (many times before) about twice I made a safe boot .... I used a computer without FCPX for a while and everything was fine. Then I installed a clean FCPX installation and so far I have no kernel panic. It's definitely been 5 days right now ... maybe it will help someone.
