Clear VirtualBox Cache on Mac

VirtualBox does not have a single dedicated cache folder; its data resides in specific directories. To reclaim space, you must target the VirtualBox VMs directory, which holds your personal virtual machines and can range from 10 GB – 500 GB. Clearing this area only helps if you intentionally remove unused machines, as it deletes the user's own data.

VirtualBox cache folders you can clear

VirtualBox has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.

VirtualBox cache and when clearing helps

Specific to VirtualBox

The app stores virtual machine folders, including disks and logs, in a specific user directory. This location contains your own data, so clearing it is not a routine maintenance step. You should only remove content here if you intend to permanently delete specific virtual machines. The app keeps global settings and registered machine lists in a separate library folder. Deleting the application itself does not remove these data folders, leaving them on your disk.

VirtualBox state after clearing cache

If you remove the preferences file, the app will rebuild it automatically upon next launch. You may need to re-enter global settings, but your virtual machines remain intact if you did not delete their folders. Deleting the VMs folder removes the actual disk images, so ensure you have backups. The command-line links and kernel extensions remain on your system until you run the official uninstaller. The app will not automatically delete these background helpers when you clear data folders.

Frequently asked questions

Yes.
Will clearing preferences delete my virtual machines?
No, deleting the preferences file only resets global settings. Your virtual machines are stored in a separate folder and remain untouched.
Do I need to remove kernel extensions to save space?
No, kernel extensions take up minimal space. They remain on your system until you use the official uninstaller tool.
