I currently have a 2010 iMac running the latest version of El Capitan. I'm thinking of buying a new 2018 Mac Mini and I would like to use Parallels 14 to run my current El Capitan system as a guest. My question is how do I prepare my current system to be used as a guest operating system in Parallels? Any advice would be appreciated. Thanks, John
You will need the OS install DVD or disk image Install parallels - when prompted by installation assistant to install windows - decline it. select the Install Windows or another OS from DVD or image file. Follow prompts till the guest OS is installed Fire up guest OS then use Applications/utilities/Migration Assistant to move your all your current 2010 imac content & apps to the new Guest computer. Good luck
ColinL3: Thanks for the feedback. Can I use an app like SuperDuper! to make an image file of my current iMac, and then use that file when I select "Install Windows or another OS from DVD or image file" as you suggested?
I'm not familiar w/ Superduper and I don't think that would work. The first install of the Guest OS (el Cap) has to be a generic version of the OS. Installation CDs that came with specific apple hardware will not work (these installs look for specific hardware combos - e.g. imac installation discs will not install on a macbook). If you are going to use a usb drive to it has to be a reformatted first to a bootable format. http://osxdaily.com/2015/09/30/create-os-x-el-capitan-boot-install-drive/
