I'm using VirtualBox 6.1.4 r136177 (Qt5.6.3) on the Mac OS Catalina 10.15.4 beta 3.

As soon as I try to start a VM (all Linux guest machines, old and new ones) I'm getting an error as below:

Effective UID is not root (euid=502 egid=20 uid=502 gid=20) (rc=-10)

Please try reinstalling VirtualBox.

where: SUPR3HardenedMain what: 2 VERR_PERMISSION_DENIED (-10) - Permission denied.

While changes in particular have been carried out for the permissions, no sure if its due to the latest Mac OS beta install.

Please help.

The suggested change to modify the setuid bit for a number of binaries worked for me.

Code: Select all

sudo chmod u+s /Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents/MacOS/VirtualBoxVM
sudo chmod u+s /Applications/VirtualBox.app/Contents/MacOS/VBoxHeadless
sudo chmod u+s /Applications/VirtualBox.app/Contents/MacOS/VBoxNetAdpCtl
sudo chmod u+s /Applications/VirtualBox.app/Contents/MacOS/VBoxNetDHCP
sudo chmod u+s /Applications/VirtualBox.app/Contents/MacOS/VBoxNetNAT

Thanks for sharing the commands.

I noticed that after the uninstall/reinstall... my VMs (stored in external drive) are not listed in Virtualbox anymore. I'm not able to add the vbox files to Virtualbox as well.

Any idea's how can this be resolved.

Thanks
