VBoxManage: error: The installer failed with exit code 1: VBoxExtPackHelperApp: error: Failed to set directory permissions on '/Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks': VERR_FILE_NOT_FOUND

It looks like the terminal application you used doesn't have permissions to create folders.

Depends on what terminal app you use. To me, I am using iTerm 2. So you can checkout the official guideline to give full disk access to iTerm 2.

Afterward, I can install virtualbox-extension-pack without problem.
