Converting an existing OS X Mojave installation into a virtual machine in Parallels. Tentative success! [WARNING - IT'S

How about continuing to use Mojave on your old Mac and buying a new M1 Mac to run the newer OS and apps?

I’m going to do that when my Studio arrives, but Snow Leopard instead of Mojave. Have an old app that won’t run past 10.7. I have my son’s old mini which I’ll run it on.

Rich,

This is the project in its entirety:

Stage 1

Find an virtualization system that runs well under Mojave and newer OSs and create a Mojave virtual machine.

- Complete. Parallels got the job done.

Stage 2

Create a virtual Mojave machine that can run a few 32-bit apps and sync the data to a non-virtual machine without issues.

- Complete. Used Parallels to create the above machine, copied Quicken 2007 to it, copied a data file to it via iCloud. Used iCloud Drive to share the file between the viortual machine and the physical machine.

Stage 3

- Complete. Create a virtual machine and use Carbon Copy Cloner via the instructions I found to virtualize a scaled down version of an active machine.

Stage 4

- Not complete. Create a virtual machine and use Carbon Copy Cloner via the instructions I found to virtualize an optimized version of a scaled down active machine. That means removing unnecessary data and apps like Scansnap, Screens, AnyDesk and several other items that don't need to be on the virtual machine.

Stage 5

- Not complete. Switch to Catalina or newer based OS on the existing machine for day to day work and use the virtual machine for the few tasks that require 32-bit apps.

Stage 6

- Not complete. Replace the existing Mojave capable Intel machine with a non-intel Mac. Use the new machine for day to day tasks and the virtual machine for the few tasks that require 32-bit apps.

Now that I've proven the concept, I am going to start to work on Stage 4.
