Did something to my computer – Steam Link Review

I downloaded this app trying to see if I could play Windows-only games on my Macbook Pro. I opened the app and connected it with my computer, then while it was loading, my mouse started moving on its own and my screen started going up in contrast, like it was melting. After forcibly turning my computer off and then back on, I immediately deleted the application from my device. After signing back into my computer, everything seems normal (as of the time I am writing this), but I’m not sure if what happened then will happen again. I hope this app didn’t do anything that would damage my computer, because I’ve already had to replace the hard drive on it once.
