I was curious if it would work. To my surprise, I was able to get Mac OS X High Sierra running on my HP laptop over the weekend. I had attempted this a few years ago, unsuccessfully, so expected a similar outcome this time. Although I don’t actually plan on using it, the Oracle VirtualBox instance seems to run well. I did have to troubleshoot an issue with the OS loading due to a hard drive configuration problem. All in all, took an hour or so to achieve a running OS X instance on my 2018 HP laptop. Pretty cool. If you are interested in trying for yourself, I suggest you google it. There are several tutorials available on line. Goes without saying – make sure you consider the legality of any actions you take (use legitimate, licensed software, etc.).
