"Run without saving changes" has only been available for QEMU, where it maps to `-snapshot`. Apple Virtualization has no such option, but DiskImageKit on macOS 27 can stack a copy-on-write layer on top of an image and Virtualization accepts the stacked image as a storage attachment. When started with the disposable option, the Apple backend now creates a temporary directory in the sandbox and gives every writable drive an ephemeral ASIF overlay there. The base image is opened read-only and is never touched. The EFI variable store and the macOS auxiliary storage are cloned into the same directory so firmware settings are not persisted either. The directory is deleted when the guest stops or when start fails, any leftover from a previous start is discarded before the next start, and directories orphaned by a crash are swept at app launch. Removable drives attached at start or hot-plugged during the run are covered as well. A disposable run boots fresh and leaves any saved suspend state and the modification date alone, and reports the save/restore path as unsupported so closing the window offers to kill the VM instead of suspending it, matching the QEMU behaviour. The stop paths that delete a saved suspend state skip that while running disposably. The context menu, the Start intent and the menu bar extra now check the backend capability instead of assuming QEMU, and the Apple display window shows the same "Disposable Mode" subtitle as QEMU.
