Thanks for your help.

2 Macs, with different macOS versions, but the same kernel extensions. No panic in Safe mode.


I think it is the kernel extensions.


If this is what your company is offering you for remote access, then you may have to live with it, or complain to your company IT department.


If there is another IPsec based VPN you could try, maybe you could still connect to your company, and not get kernel panics. Just a thought.


I must stress that reading kernel panics is a bit like reading "Tea Leaves", and is not perfect, so my opinion is just an educated guess, but it is not proof your VPN kernel extensions are the cause.

Oh yea. Do you have the software versions tested for your version of macOS. Again, sometimes kernel extension vendors need to have per macOS release versions because the inside of the kernel is a bit of the "Wild Wild West" with respect to interface stability and standards (namely the macOS kernel development group thinks they can do what they want, and if you the 3rd party kernel extension writer want to play in kernel space you have to keep up or get left behind).

Thanks for your reply.


USB Keyboard and mouse, Eizo monitor.


Boots fine.

The kernel panic occurs after using for a few hours. Didn’t get a panic in safe mode.


Did a clean install on Sunday but the problem continues.


Do you see anything in the panic report that suggests what is wrong? The iMac is new and has been happening since day one, trying to figure out if it’s hardware or software that’s the problem.


Thanks again.

Macbook is running High Sierra. iMac is running Catalina. It shipped with Mojave.


Kernel panics occurred in both Mojave and Catalina.


I seem to be the only one experiencing such a fault which makes me think the problem is hardware. The panic reports only show what is running and not what the problem is, is that correct?


I will try and contact their support again and try to get them to investigate.


Thanks again

I get that it’s the software causing the crash. Looks most likely to be Forticlient from working with it. I thought it was an issue with sleep at first because the panics occurred when I left and returned to the computer, but it has also happened when I quit the connection.

What I’m not understanding is why this conflict only happens on my iMac (ignore my macbook - others are using various macs to connect) and why I’m being told it’s most likely my machine.


I have opened a ticket with our IT and they’re chasing up the developer.


I appreciate your help and thanks for taking the time to reply.

#1 suspect is always 3rd party kernel extensions

com.teradici.usb-mediator	1
com.fortinet.fct.kext.ipsec	1

you have 2.


There are zero protections for kernel extensions. If the developer messed up, it is the equivalent of sticking your finger in an electrical socket. Oops!


Safe mode will Not load the 3rd party kernel extensions, so the fact that it did not panic during Safe mode is another indication that it might be your 3rd party kernel extensions.


#2 cause for a panic is 3rd party RAM. Do you have original Apple RAM or did you get 3rd party RAM? If you have 3rd party RAM, you might want to run Rember overnight.

.

Quit as many apps and background tasks as you can (such as menu bar items) so more RAM is available for testing.  Booting into Safe mode <http://support.apple.com/kb/ht1564> can also free up more RAM for testing, by not loading any 3rd party additions you may have installed.

Set Loops: [X] Maximum

and run overnight


#3 kernel panic cause is broken USB device. This can be a

  • broken USB cable
  • broken USB hub
  • broken USB mouse, keyboard, etc...
  • broken USB disk
  • etc...

If you suspect broken USB device, you just disconnect all such devices. If you depend on a USB keyboard/mouse, see if you can use another set (any generic keyboard/mouse will do for testing purposes).


After that it becomes much more rare.


In this case, I would strongly lean towards your 3rd party kernel extensions.
