As you know, macOS has a .app extension when you download, and this package is directly not usable for virtualization. The latest version of Parallels accepts the Mac OS app installer for a new guest OS. Parallels has an inbuilt facility to convert the macOS installer app to HDD, a propriety disk image format. However, freeware and paid virtualization apps like Virtualbox needs the OS in .ISO or a compatible disk format. Let’s see how we can make an ISO disk from the Mac OS installer.
