Apple announced the next version of macOS at WWDC 2017 today. The new operating system, called macOS High Sierra, has several improvements over the previous iteration starting with an improved Safari browser.
While Safari is not as widely used as Chrome, it is a quick and efficient browser for Mac users that uses fewer resources and runs JavaScript up to 80% faster, according to Apple. New on the upcoming Safari revision is “autoplay blocking” for both audio and video, so you are not blasted with video that autoplays upon going to a website.
