Parallels is great - this in terms of performance and usability. I use it to have dedicated Windows 10 guests for each of my clients (I am in IT/business consulting services) on my laptop. My issue: I use a Lenovo Thinkpad Yoga (as Apple has no touch screen Macbook) - but on Ubuntu/Debian only VMware Workstation is available. (to be honest - many performance related issues like network performance between host an guest). None of them were on Parallels on OS X Catalina... Request: Have a product "Parallels on Debian/Ubuntu"
