[RESOLVED] Is it not possible to make a Sequoia beta VM

I tried setting up a Sequoia beta VM, but it starts up and immediately shuts down. I downloaded the IPSW for Build 24A5264n from Apple and began the installation. The VM was created very quickly but then failed to stay running.

What is missing from Parallels that makes that fail, or is it simply that the beta itself is having difficulties with the VM?

 

I have download on ventura the macos 15 installer and ran the pkg.
https://swcdn.apple.com/content/dow...zcxnr1u85utqhl124vmsph1c/InstallAssistant.pkg
After that i have under apps the MACOS 15 install and run but do nothing in the app.
After they run i make a usb boot stick with the terminal.
Insert a usb stick and rename to Untitled
Start terminal en copy the command.

sudo /Applications/Install\ macOS\ 15\ beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

After so 15 minutes the stick is ready for use.
Under parallels i choose a new VM en choose usb stick and start the VM.
He install the USB stick on the VM.
after 40 minutes the VM work.
Turn off the VM and make a snapshot.
After that you can test the VM.
On my VM parallels tools don't work, i result in a frozen screen with apple logo.
On the VM you can't login apple/icloud it gives a error and apple say it in the beta 1 changelog this problem.

 

I found elsewhere (discussion of a post on the Eclectic Light Company) that I can install it from the IPSW, if I install the beta of Xcode 16. I did, and the installation proceeded without incident.

 

I created a VM with macOS Sonoma and ran the MacOS 15 beta update. This worked.

 

Oh, now at least I'll know. Thank you

 

I'm running both the Insider Dev and Canary as VM's on Sonoma. I have had no problem with the VMs with the Mac beta updates or with the Mac with the Insider updates.

 

Ooops! That should be Sequoia. I'm running Version 15.0 Beta (24A5279h).
