Has anyone been able to update their guest OS to the 2nd beta. The option for Beta updates doesn't show in my VM. Im using UTM.
Got a tip for us?

Update Sequoia VM to Beta 2

if it is, you won't be able to start by upgrading, you'll have to make a new VM using the IPSW, running on a Mac that's also running macOS 15.
I wish I had known about that earlier today! I updated my beta 1 by using the full installer for beta 2. This is with VMware Fusion on Intel (2019 iMac) host.
On Intel Macs you can sign in to enable the beta program just like on a physical Mac.
My clean install Sequoia VM is unable to sign in and is not offered updates. Maybe it is different with a Sonoma VM updated to Sequoia.
This worked for me, too on an M3 MBP! Thanks a ton! It saved me hours of work and disk space. I could simply upgrade my MacOS 15.0B1 VM under UTM to 15.0B2. Also, unless you are running a beta guest VM inside a Sequoia host (which kind of defeats the purpose of sandbox testing) you're not going to be able to log in with your Apple ID or use iCloud services.
No, it is not. And probably won't ever work without a Sequoia host. It's a security feature.
Hi. DO you have a similar script for upgrading from 15.0 beta 6 to 15.1 beta 2? we tried the script you shared but no luck.
What were your symptoms? I have a Fusion VM which started as macOS 14.5 and I have incremental updated with beta 3 to beta 7. Except for the most recent these updates just worked nice and cleanly. The beta 6 to 7 upgrade did a few reboots with video not working (jumbled up random lines), but I just left it alone and it came right in the end.
(I am using a VM which started as macOS 14, because that continues to allow iCloud connection.)
If you're using Fusion, you're on an Intel Mac, which does not have the iCloud limitations that happen when virtualizing macOS on Apple Silicon computers.
How do you know that? My experience is that there are similar limitations in the macOS 15 betas on Intel. I would like to know how to use iCloud on a VM built with macOS 15 installation media.
Fusion can't virtualize macOS on Apple Silicon. Virtualization solutions on Apple Silicon which support virtualizing macOS use Apple's hypervisor framework, which is what prevents the iCloud logins from working. Fusion on Intel uses its own virtualization software which does not have the limitations that Apple built into its framework.
Signing in to iCloud should work on Intel-based virtual machines.
Works with macOS 14, not (for me) with macOS 15. Do you have any examples about how to get it working?
As best as I can tell, the following change should enable updating to the 15.1 beta
diff enable-beta-updates.sh.old enable-beta-updates.sh

However, it didn't work when I just tested it in a macOS Sequoia VM. It may be necessary to build a new VM from scratch to get the 15.1 beta. (Use the Migration Assistant to get your data migrated from the 15.0 VM.)
I built a fresh Sequoia VM in UTM running under Sequoia. I was able to login to iCloud in the VM.
However, Software Update in System Settings doesn't offer the ability to enroll in Beta Updates in the VM even though I'm logged in. That's the only reason I rebuilt my Sequoia VM so I could enroll and update to 15.1 beta. (Sigh)
