Can you provide an example command using PlugInKit -a with _securityagent user and launchctl? your response to me doesn’t provide the closure that I’m looking for. currently the host app approach using _securityagent user ends with a Trap. I will try to find the reason why / error soon.

No iCloud support is an M1 VM was a terrible decision made by Apple. I cannot test my own software that has Sign on with Apple on an M1 VM. Can't use any iCloud storage that an app might use during testing on an M1 VM. I cannot build software with a Apple Developer account on an M1 VM. I am being redundant here to make this painfully clear. Please add in this feature and support iCloud 100% inside a VM. Please don't make it terribly hard for any VM author to support like forcing them to get an unobtainable highly restricted entitlement. This should have worked out of the box from day 1. It should just be a flag in the framework such as, iCloud supported YES or iCloud supported NO via an info.plist. Whoever chose not to allow iCloud within an M1 VM wasn't considering the implications this has on all Apple Developers. Because of this, I have to do all test directly on bare metal.

I added Feedback as well on this same issue: FB12024018 I've seen it on other macOS versions as well from 10.15 and up.

On Anka Developer VM with 12.6.3, my auth plugin using SFAuthorizationPluginView works fine without any issues with user select animations. If its not fixable on bare metal hardware, it would be nice to disable the select user animations when an SFAuthorizationPluginView is present. It does however, look very slick when the select user animations do work without delay. The issue is pre-existing with Apple's own sample code and that should have thrown a red flag internally.

I have seen this was well. Please post an update when one is available. Thank you!
