Today Apple released iOS 11.1, watchOS 4.1, tvOS 11.1, and macOS High Sierra 10.13.1. These updates bring some anxiously awaited fixes for the big updates that Apple released in September, and I can finally say that these upgrades are, in my opinion, finally ready for the masses. If you have compatibility concerns such as Microsoft Office 2011 or custom software that has not yet been fully tested you may need to address that first, but by and large I feel I can confidently recommend that nearly everyone install these upgrades, especially because this is the only way to get the Wi-Fi KRACK security hole patched on iOS (macOS 10.11 and 10.12 got security patches today to fix that security hole).
Problems with speed on older devices and battery drain seem to have been addressed. Apple also returned the feature that allows 3D-Touch for switching apps.
As always with any upgrade you should be sure that you have a full backup before installing. No software is perfect and issues are rare during upgrades but it’s no comfort how rare a problem is when it happens to you. So please check to make sure you are backed up before installing the update.
