But if you are doing a clean installation, prefer the Create a virtual hard disk now option and click the Create button to resume. If the virtual machine disk is ready in the Virtual Hard Disk window, you can add it and run your macOS system directly.

Under normal conditions, a macOS virtual computer runs smoothly with a memory size 4096 (4 GB).Īlso, set the number of 2 or 4 vCPUs for the macOS system to work more efficiently on the virtual computer. If your host RAM has a capacity of 16 GB, assign a RAM size of 4 GB or 8 GB in the Memory Size window. You should allocate RAM size and virtual processor to the virtual machine according to the hardware performance of your host computer.
