The other option, admission of the sad fact that your Mac doesn’t connect to the internet, resulted in a dialog trying to persuade me that I really wanted to try again. Once that’s done, you start that VM up for macOS to complete installation with personalisation and configuration, just as you would when your Mac first starts up into a new macOS boot volume group.Įarly during that process, macOS 13.2 detected that no network was available, and offered to try connecting with Ethernet. First, the VM has to be installed from an IPSW image into a new VM bundle. Setting up a macOS VM in ViableS is a two-step process. This simply adds a checkbox so you can run a VM with or without its NAT network connection device. If you want to try this out yourself, ViableS 1.0.8 (beta 8) is available from here: viables1b8 This is an update to the sandboxed version of that app, ViableS. To investigate this, rather than trying to block network connections on a Mac, I built a new version of my lightweight virtualiser Viable with the option to run completely locked down in a sandbox, without any shared folders, and with no network device available. If network connections are now so important to Macs, what can a Mac running Ventura do without being connected to a network? Can it still run apps, and how does it cope with tasks like Gatekeeper checks? This article explains what does and doesn’t work when a Mac running Ventura has no network connection at all.
