- MacOS Sierra (version 10.12) is the thirteenth major release of macOS (formerly known as OS X and Mac OS X), Apple Inc.' S desktop and server operating system for Macintosh computers. The name 'macOS' stems from the intention to uniform the operating system's name with that of iOS, watchOS and tvOS.
- Adobe has finally ended support for Flash Player from 1 January 2021, and it will altogether disable the plug-in from 12 January. However, the software will continue to remain on your system. It is wiser to uninstall Adobe Flash Player from your Mac.
- Apple is stepping up its fight to rid the world of Adobe Flash. Apple's Safari 10 browser, which will ship with MacOS Sierra later this year, will deactivate Flash by default.
