Managed Apple ID works for iMessage on bare metal, but fails in macOS VM (same hardware)

Hi all,

I'm running 2 macOS VMs on a bare-metal Mac (host is also macOS). I'm seeing inconsistent iMessage sign-in behavior depending on the Apple ID type and whether it's bare metal or virtualized:

Managed Apple ID (ABM-issued): signs into iMessage fine on the bare-metal host.

Same Managed Apple ID: fails to sign into iMessage inside the VM on the same physical machine.

Personal/basic Apple ID: signs in fine in the VM without issue.

Has anyone run into this specific combination — MAID working on bare metal but not inside a VM, while a personal ID works fine in both?

    Apple is pretty open about not all of their services working on virtual instances of macOS, a lot of their features are bound to the UUID of the hardware which the VM does not have or inherits from the host device.

     

    Generally speaking macOS VM’s are not really useful beyond testing and validating, and even then there are a lot of gaps.

    Thanks, that makes sense.
    Do you know if there's a difference in how Apple validates a Managed Apple ID vs a personal/basic Apple ID during iMessage sign-in? In my case the personal ID signs into iMessage fine inside the same VM where the Managed ID fails — so it seems like MAID triggers some additional device-trust check.
