Can’t Upgrade a Sonoma VM to MacOS Sequoia Beta? Try This
If you already have a MacOS Sonoma virtual machine setup in UTM, Parallels, VMWare, VirtualBuddy, or otherwise, you may be interested in upgrading the MacOS Sonoma VM to a MacOS Sequoia Beta VM.
One simple way to accomplish this, one might think, is to use a developer Apple ID within your Virtual Machine, and install directly from there. However, using an Apple ID within a MacOS virtual machine is not supported, and therefore MacOS VM’s are typically used in such a way that no Apple ID is associated with them or used within them, so in those situations you will need to rely on another method. While one option is to download a MacOS Sequoia installer and then copy it to the VM, another approach is available that relies on defaults commands to change the software update catalog on the virtualized Mac. This will allow the macOS Sequoia beta to appear as an available upgrade, even if no developer Apple ID is associated with the virtual machine.
