Hello. I have an iMac running on High Sierra (2009) and would like to install the home version of Parallels in order to run a couple of programs on Windows 10 occasionally. I am just a little concerned about the ease of installation, as I can't find any information on this aspect of it. I am in my eighty-sixth year, and wonder if I should take it somewhere to have it installed. I don't want to spend money on something that might prove to be a problem. Any advice appreciated.
