Apple on Wednesday updated macOS Catalina, probably for the final time except for security-only fixes.
The update – the sixth since Catalina debuted in October 2019 – is also a sure signal that one of its forebears, macOS High Sierra, is now close enough to retirement that it may as well be shopping for loud shirts, ugly sandals and an enormous RV.
Catalina 10.15.6 sports a very short list of improvements to Apple News, fixes two bugs and adds an option to optimize video streaming on HDR-compatible Mac laptops. Apple said that the option would extend battery life for aggressive streamers.
