Is the problem dependent solely on the version of the guest? For example, if you try macOS 26.4 host with macOS 26.5 beta guest, do you still see the problem? Correct, we test al versions back to 12.x and we only see this with 26.5 so far. Does this only affect your VM product? Or can you reproduce it with other common Virtualization-based apps? I just tried another tool and the same thing happens.

Oh, I closed out that suggestion I opened soon after opening it. Thanks for opening your own for the docs thing! I want to first thank you for helping us multiple times now. You're wonderful to work with. So thanks! Second, I didn't ignore what you wrote, I simply just don't ultimately need documentation. I wanted this to work without an active logged in user. There are hundreds of things over the years that aren't documented in the official docs so I've learned to just not expect much from Apple's docs and collect them through experimentation or the mac admin community postings. Worse, even if you added these docs, I couldn't trust that it would be updated or current. This is not to offend or anything, and maybe I'm wrong here and things have changed, for sure, but I just wanted to express the general mindset I and many others in the macOS space have towards documentation. Thanks again!!

AHA, fixed. I had to do these on the host. Something was wrong with the host's password I guess :shrug: sysadminctl -oldPassword "${PW}" -newPassword "${PW}" security unlock-keychain -p "${PW}" ~/Library/Keychains/login.keychain-db

Opened FB22523292 as suggestion

Ok, sorry about this. I just tried manually and it looks like the error message on a 15.x host is different and wasn't being caught on our end. Does not look like a regression anymore. And this is using unlock-keychain too. I need to dig a bit more on my end. It's unclear to me how this has been working on AWS EC2 Mac since they don't have a logged in user to the GUI.

Hmm, yeah, I tried the unlock method already. That was a solution at some point according to google, but honestly I've never had to use it. I tried and the error is still: Thu Apr 16 10:07:11 40 5a27c75d-0a35-4aeb-9ec1-e77e77f66210.log (ankahv) 578: 5a27c75d-0a35-4aeb-9ec1-e77e77f66210: failed to start: Error Domain=VZErrorDomain Code=-9 "The virtual machine encountered a security error."

We only started seeing this fail when we upgraded to 26.4.1 host OS. Are there any other logs or tests I can run to help clarify this for the team?

To further clarify: Unless autologin is enabled or we sign in to the GUI/VNC with a user, we can't do much of anything with macOS VMs.

No log in to the GUI at all, then run the tests.

Weirdly I had to install it twice on one older M1. I did it first with sudo installer -pkg MobileDevice-26.4.pkg -tgt / and then had to use the GUI to install. Just FYI for anyone who has the same issue

Little request for the devs at apple: Please make these MobileDevice pkgs available on the downloads site for every release. I shouldn't need to download the whole Xcode.app and extract it manually each time I need this pkg. <3

I extracted the MobileDevice.pkg from 26.4 Xcode and installed it on 15.x. I can now create a VM for the 26.4 release.
