I have s couple of Mac applications I want to use that will only run on MacOS High Sierra. I own Parallels 19 Pro and I have both an M1 Pro MacBook Pro and a Intel Xeon iMac Pro 27" that could be used as the host computer. Will Parallels 19 Pro support MacOS High Sierra as a guest OS? If not, what is the most recent version of Parallels that can support MacOS High Sierra as a guest OS? I searched the Parallels Forums and did not find a thread that answers this question. Thanks in advance to anyone who can help answer this.
