Mac : There was an error while executing `VBoxManage`, a CLI used by Vagrant

For macos you can update privaciy and security permissions.

here is a link: https://medium.com/@Aenon/mac-virtualbox-kernel-driver-error-df39e7e10cd8

Proceeding with the following steps helped me out:

1. restart the virtual box using:

   sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart
   

2. Stop vagrant as follows:

   vagrant halt
   

3. start vagrant as follows:

   vagrant up
   

Go to settings => security & privacy => general

and allow permission.

Just had the same issue after latest OS update (Big Sur). Steps I had to get through in order to get it working again:

• Uninstall VirtulBox and reinstall it (it shouldn't delete your VMs)
• run homestead box update in Homestead directory
• run sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart
• Weirdly enough, followed @Alperen Tahta 's link and restarted laptop after I changed permissions.
• Vagrant up and tada!

It took me a few steps to get there but I now have my VMs up and ruinning as before.

Hope it helps 👍🏼
