VMs can't boot with Network Mode set to Bridged on Apple M5 Pro machines

Apple’s shiny new M5 Pro is leaving virtual machines stuck at the starting line

TLDR: Virtual machines on Apple’s new M5 Pro can freeze on startup when a certain network-sharing option is turned on, even though other settings work fine. In the comments, users argue over whether UTM is at fault or Apple broke something system-wide — with extra chaos because Parallels users say they’re seeing it too.

A fresh GitHub complaint says virtual computers in UTM won’t start at all on Apple M5 Pro machines if users pick the setting that lets the virtual machine connect more directly to the same network as the real computer. Switch that setting to safer alternatives like Host Only or Extended, and everything suddenly behaves. So yes, the machine runs — until one very specific option turns the whole thing into a frozen loading-screen horror show.

But the real spectacle is the comment section, where the mood swings from puzzled to full tech soap opera. One user summed up the first reaction with a dry, perfect: “That’s super weird.” Then came the veteran GitHub cynicism. Aurornis delivered the thread’s most dramatic read, basically saying this is the classic routine where someone insists it was never supposed to work, everyone else points out it works on other Macs, and then an Apple beta quietly fixes it anyway with zero changes from the app itself. In other words: is this a UTM bug, an Apple bug, or just another episode of “blame ping-pong”?

The speculation got juicier when one commenter pointed at the M5 Pro’s fancy new wireless chip via a Wikipedia page, hinting that Apple’s newest hardware may be the real diva here. Another dropped the spicy elitist grenade, “Don’t try to do professional work on consumer hardware ...” Meanwhile, a Parallels user chimed in to say they hit the same bridged-networking mess on M5 too — which only poured fuel on the theory that this problem is bigger than one app. The vibe? Equal parts bug hunt, finger-pointing, and “lol of course the expensive new Mac broke something weird.”

Key Points

  • An open GitHub issue reports that VMs on Apple M5 Pro machines fail to boot in UTM when network mode is set to Bridged.
  • The reporter tested `ubuntu-24.04.4-live-server-arm64.iso` and reproduced the problem.
  • The same VM reportedly boots successfully when network mode is set to Host Only or Extended.
  • The reported environment is UTM 4.7.5 (118) on macOS 26.3.1 (a) using an M5 Pro Mac.
  • The app does not crash; it remains stuck on the loading screen immediately after Run is pressed.
