Troubleshooting macOS Sierra Problems

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.
We’re compiling a list of common problems in this troubleshooting guide to remedy issues with the macOS Sierra download, installation, update, and post-install process. Unfortunately for me (but fortunately for you readers), I personally have had the joy of encountering many of these problems during and after updating one particular MacBook Pro to Mac OS Sierra 10.12, so I have very recent extensive firsthand experience with troubleshooting much of what is covered here.
