As we get to the final release and benchmarks come out, we’ll have a clearer picture. At what exact tasks? We don’t know yet but Apple made a big splash at the WWDC keynote, making sure to highlight just how much faster Safari was than Chrome. Faster SafariĪccording to Apple, Safari in High Sierra is 80% faster when it comes to JavaScript performance than Chrome. It has built-in encryption, crash-safe protection, and simpler backups thanks to the Snapshot feature. APFS runs on a 64-bit architecture, is much faster and far more stable than the outgoing file system. High Sierra brings Apple’s APFS file system to the Mac ( iOS got it with 10.3 update). Still, there’s a lot of new exciting stuff and surely a lot of small changes and improvements! macOS High Sierra Features and Changes 1. The Mac is a professional tool and more stable the OS, the better it is for the pro users. And right now, that actually sounds like a great thing. While there are new features and newer technologies, the main focus in on improving performance, fixing bugs and refining features. It’s on the same lines as Snow Leopard and Mountain Lion. As the name suggests, macOS High Sierra is a refinement update.
