Bridged network interface doesn't work on macOS 26

[lfnpcsoft]

I've checked the Issues, haven't found anything similar.

Describe the issue
When I opened a VM that worked on a previous macOS version (15.5), it didn't boot successfully and showed error messages like this: "QEMU error: QEMU exited from an error: gemu-aarch64-softmmu: -netdev vmnet-shared,id=net1: cannot create vmnet interface: general failure (possibly not enough privileges)" and then it said "Internal error trying to connect to SPICE server." When I removed the bridged network interface and restarted the VM it worked fine, and there remained an interface connected through "Shared Network" and the internet connection inside the VM was available

Configuration

• UTM Version: 4.6.5
• macOS Version: macOS 26
• Mac Chip (Intel, M1, ...): M1 Pro

Crash log
The UTM app itself didn't seem to crash.

Debug log
debug.log

Upload VM
The problem seems to happen whatever the guest OS is and whatever architecture it runs on, so I don't think it's related to a specific VM.

The same problem, I hope to adapt to the new version as soon as possible.

It seems to work fine for me on beta 2 (25A5295e) can you confirm if it's still an issue?

Same. See here: https://github.com/utmapp/UTM/issues/6003#issuecomment-3508864232

Might be duplicate issue.
