![]() Indeed, if anything, the first run of apps like Xcode was started with less delay than when an internet connection is available. I encountered no difficulties or delays performing any of these tasks. booted into Recovery mode and accessed Startup Security Utility and other tools.created a new project in Xcode, built and ran its Hello World demo app.ran Xcode for the first time, and completed its installation.ran one app with its quarantine flag set.ran several apps for the first time, without quarantine.Running the VM in a sandbox, without any network connection or shared folders, thus completely isolated from the host Mac except through input devices (keyboard and trackpad) and its display device, I then performed the following tasks: In other circumstances, that could easily be performed using a removable disk. I did that by running the VM briefly in Viable, using a shared folder, before returning to my networkless VM. To be able to assess what effects the absence of a network have on macOS and apps, I then needed to copy across additional software including Ulbow and other utilities, Pages, and the Xcode 14.2 xip file. ![]() Many of us pointed this out to Apple early in Big Sur’s release cycle, but Apple has chosen not to provide standalone macOS updaters any more. If you had no option to enable a network connection, the only solution now is to use the full installer app. There was a time when Apple provided standalone updater packages for macOS, but that came to an end with Big Sur, and its switch to this new update mechanism. ![]() Of course it had no Location Services, so didn’t have a clue which time zone it was in, so that and its clock had to be set manually. Once that was complete, I started the VM without the network, and it ran fine. Of course, without an internet connection, Software Update was unable to update the VM to 13.2.1, so for that I shut it down, enabled the network, opened that VM again and installed the macOS update. But I persevered through its warnings, and the remaining configuration completed successfully. 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. This time the fact that I was streaming was a bit more noticeable, but the game remained entirely playable.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. The iMac also stayed on the wireless connection, and I again tried out Cuphead with the Very High video quality setting. Using the same hardware I ran a second test, this time with my Xbox One using a wireless 5GHz connection rather than a wired connection. ![]() I felt like I was playing the game with the Xbox One connected to my TV, and I was just as good (bad) at the game here as I am with a regular setup. With Cuphead (opens in new tab), a game that requires precision movements and perfect timing, I noticed virtually no latency issues. Both the Xbox One and iMac were in my office, located about 30 feet away from the router, and I chose the Very High video quality option before launching. I initially tested OneCast using a regular Xbox One connected to my router with an Ethernet cable, and a late-2015 iMac (Intel Core i5, 16GB RAM, AMD Radeon R9) running macOS Sierra 10.12.6 and connected to my router on the 5GHz band.
