I have two identical Mac Minis (Mid 2010), 2.4 GHz runing 10.12.6. The one I use for work is fine. The one I use at home is running very slow.
In ran EtreCheck, and discovered some strange results, including these:
The following internal tasks failed to complete:

/usr/bin/codesign -vv -R=anchor apple generic /Applications/Preview.app/Contents/MacOS/Preview
and:
