How read-write disk images and those used in Apple silicon virtual machines use sparse file format to save space on disk.
Is it possible to update a VM running macOS Sequoia to version 15.4? Three attempts, three failures. And why are all those file creation dates wrong?
How to create and set up macOS VMs for virtualisers. The structure of a VM, creation and first run explained. How to enhance it, and how to run it in isolation.
