My virtual copy of MacOS doesn't have mount_virtiofs or /Library/Filesystems/virtiofs.fs What is the proper way to get these installed?
Trying to mount a shared folder with mount -t virtiofs on virtual MacOS
Try in /System/Library/Filesystems/virtiofs.fs (and /System/Library/Filesystems/virtiofs.fs/Contents/Resources/mount_virtiofs)
Support for filesystem sharing was introduced in macOS Ventura. Ensure that both the host machine and your virtual Mac has this version of macOS installed to use this feature.
If you are a registered developer, you can download the macOS Ventura beta restore image on the Apple Developer site.
