I’ve told you more than once that it’s a bad idea to upgrade your Mac’s (or any device’s) operating system immediately after its release. Sadly, that’s not an option for me because of my vocation. I had to disobey my own advice (yet again) and install macOS Sierra 10.12 on my main Mac the day it was released.
The major update to Apple’s Mac OS X, is no more OS X 10.12, instead, it’s named macOS Sierra. The brand-new desktop operating system macOS Sierra comes with Auto Unlock, Optimized Storage, Siri, Universal Clipboard and many more.
For most users, installing macOS Sierra has gone without a hitch and they’re left with a trouble-free Mac that works great with the latest macOS system software release. But, not everything goes smoothly for everyone, and sometimes updating to macOS Sierra can lead to a variety of problems.
