I have just created a macOS 10.12 VM as offered in the Control Center. It starts up and shows me my usual user icon along with a Guest User. However, when I specify the usual password for accessing my user account it is rejected with only, after a few attempts, a message saying I can '...reset it useng your Apple ID'. I haven' progressed any further - what should I be doing? Really I wanted to create a VM running my current macOS 10.14.6 (to run parallel to Catalina). Any suggestions how I can achieve that would also be gratefully accepted! Or directions to further hints.
