iMac 27" 5K 2020 shuts down randomly, Lightburn in error message

BenceBokor · December 16, 2020, 2:47pm

Hi there,

As we’ve started to use macOS, we switched to Lightburn from another software.
Since that, the computer shuts down randomly, the error message shows LightBurn as the corresponding process.

We’d like to know if the issue is software (LightBurn for Mac) or hardware (iMac) specific.

Here the complete error:

Any help is appreciated.

Best Regards,
Ben

If you can send me the entire content of the crash dump that would help (attach it here if you can). Which version of MacOS are you running? It looks like it says “October 2020” which could mean Big Sur. Some of our users have been successful with that, but others have had a few issues - I haven’t tested LightBurn with that version yet.

BenceBokor · December 17, 2020, 8:38am

Thank you, Oz. Yes, it is indeed Big Sur.

I’ll try to get the full crash dump next time it occurs, and will check, if old dumps are still available on the disk.

Important to tell, that LightBurn works, but there’s like one crash every 1-2 days.

Kernel Panic reports can be found at /Library/Logs/DiagnosticReports

From the Finder>Go>Go To Folder : /Library/Logs/DiagnosticReports

Three reports are handy for debugging as they give you more situations to filter on.

While we’re at it, can you describe your machine? What is it, more specifically what accessories are connected, and have you tried setting your language to English and running a few days?

Kernel panics can be (mostly) broken down into two areas: third-party hardware misbehaving; third-party kext (kernel extensions) misbehaving.

Almost never a Mac hardware issue, as they test the heck out of Apple hardware.

If you have loaded any non-apple-store software, it would be handy to know.

BenceBokor · January 6, 2021, 12:48pm

Pretty vanilla iMac 27” 5K 2020, no attached hardware (maybe a flashdrive every now and then).

We’re having another issue, sound daemon dies every few days, no audio to be heard.

Meaning, it will most definitely be sent back for checkup & service, but the lightburn mention in the crash made me to check with you guys.

kerrylaw · January 10, 2021, 12:32am

Why are you running “virtualbox”? You have the system partitioned with windows OS also? I believe this is the issue.

BenceBokor · January 14, 2021, 2:17pm

No sep. partition, The VirtualBox is running to export project files from an old software.
Most of the times it’s not even running when the crashes happen.

Check these things out: 1) Uninstall the Symantec software by following the developer’s instructions if it is installed. 2) Uncheck Power Nap option in the Energy savings preference. 3) Uncheck “Automatic graphics switching” option in the Energy savings preference. Let us know.

BenceBokor · January 19, 2021, 6:22pm

Hi @kerrylaw,

thanks for your feedback.

there’s no Symantec software installed on the device
powernap was never enabled
there’s no graphics switching option on my iMac (none of them has this)

Bonjour · January 21, 2021, 9:37am

I suspect virtual box has associated itself with a real device and is holding on to it via a plist or similar configurator. The configuration is unable to be resolved with the kext in use.

I run VB and use hardware directly, but only per-session. I would check your virtualiser for hardware tie-ins.

These are the kexts in use, which lends themselves further to being suspect.

org.virtualbox.kext.VBoxNetAdp 6.1.16

org.virtualbox.kext.VBoxNetFlt 6.1.16

org.virtualbox.kext.VBoxUSB 6.1.16

org.virtualbox.kext.VBoxDrv 6.1.16

Network adapters and USB.

Have you run an update of the VB driver and UI support suite? (can’t remember their terminology). It mounts as a device on your VBs and has Mac OS integration utilities.

i5 on Mojave 10.14.6

BenceBokor · January 25, 2021, 1:04pm

Thank you, @Bonjour!

I’ve removed VB completely, will see. If the problem is gone, I’ll try Parallels or something else.

Bonjour · January 27, 2021, 1:25am

I’m running VB on the machine I use for LB. Never had any issues.

It’s probably not VB, it’s the way it’s configured that’s the problem.

Uninstalling may not remove all the problems - you need to look at something that cleans up after itself, like CleanMyDrive.

Hi there,

since we’ve removed VB the issues went away.
There was no extra setting in its configuration, so I can’t think of a reason it could possibly affect its run.

Anyways, sorry for stealing your time, thanks for the tips.
