Size

When creating a new image, this is the size of the new image. You can toggle between “MB” (mebibyte) or “GB” (gibibyte).

Raw Image

If selected, a raw empty image will be created inside the .utm package. If the host file system containing the .utm is APFS, then a sparse file will be created (zeros will not take space).

If not selected, a QCOW2 disk image will be created inside the .utm package. The QCOW2 format will grow as the disk image grows.
