Hello, I am getting the following error while trying to start my virtual machine
Failed to open a session for the virtual machine sparkvm.
Failed to load R0 module /Applications/VirtualBox.app/Contents/MacOS/VMMR0.r0: An unknown (and thus untrusted) group has write access to '/Applications' and we therefore cannot trust the directory content or that of any subdirectory (VERR_SUPLIB_WRITE_NON_SYS_GROUP).
Failed to load VMMR0.r0 (VERR_SUPLIB_WRITE_NON_SYS_GROUP).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Any help? couldn't find anyone else with the same error. Mac OS X 10.10.5
thanks
Failed to Open Session due to "unknown group..."
Re: Failed to Open Session due to "unknown group..."
Solved it myself.
Went to the folder Applications > get info> then on the groups with access I put all of them except System to Read Only. Problem solved.

Re: Failed to Open Session due to "unknown group..."
May I suggest that you don't do this sort of thing manually, but instead go in the "Disk Utility" and "Repair Permissions".
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

Man, sometimes I really hate how Apple tones down things and thinks that we're children!
But, there is hope, even if the standard 'diskutil' command line has removed the 'repairPermissions' option. From http://osxdaily.com/2015/11/04/verify-r ... -mac-os-x/ :
Run that in the Terminal and see what the output is.

Re: Failed to Open Session due to "unknown group..."
Hi, I know I'm late to this, but I just had this same issue with macOS 12.5.1 and found the solution by myself. I'll add it here in case anyone needs it.
The permissions of the /Applications folder need to be the following:
drwxr-xr-x (permissions) root (owner) admin (group)
You can set them using the Terminal. Use these two websites to help you:
controlc. com/1cd622451 (remove the blank space to open the link)

Re: Failed to Open Session due to "unknown group..."
Well thanks for trying to help, but "late" is putting it mildly. The original question was asked over 7 years ago, which is 6 years before MacOS 12.5 existed.
Time to lock this I think.
