Is it safe to download this video converter?
My iMac has 5k retina display. Since we want to download movies and many are not 5k at all, can we use this MacX Video Converter Pro that will convert any downloaded movie to 5k? Here's the link to the free download https://www.macxdvd.com/mac-dvd-video-converter-how-to/play-hd-mkv-mts-avhcd-vid eo-on-imac-5k-retina-display.htm
Would appreciate some advice. Thank you.
iMac (Retina 5K, 27-inch, Late 2015), OSX El Capitan 10.11.4
