Many users reported that updated macOS Sierra boot-up time increased a lot. How to speed up macOS Sierra? It's quite easy. Head to System Preferences > Startup Disk > primary disk and click "Restart" the Mac computer. If it doesn't fix slow Mac macOS Sierra after upgrading to macOS Sierra, reset PRAM.

Apple has instructions to reset PRAM:

Shut down your Mac.

Locate the following keys on the keyboard: Command (⌘), Option, P, and R. Turn on your Mac.

Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.

Hold these keys until the computer restarts and you hear the startup sound for a second time.

Release the keys.

After resetting NVRAM, you may need to reconfigure settings for speaker volume, screen resolution, startup disk selection, and time zone information.
