Apple updated both major operating systems, eliminating a very annoying bug, too.
Users of an iPhone 8 or X could experience the problem that the touch function or the ambiance light sensor was not working properly after a display repair (third party), which is now fixed. Apple warns in the upate notes though, that a non-Apple part may be of less quality and cause problems. Apple, however, is not actively keeping these parts from working.
Both systems got huge security updates. For macOS that resulted in an update size of 1 GB. This is why we love Apple: Security updates are always around the corner, no matter what it takes. For iOS, Apple tried to make the encryption safe again. Currently, it is possible to crack it with an device called “GrayKey”. Apple is working hard to make iOS bulletproof again.
