Sierra Finder aliases appearing as generic icons
Since updating to macOS Sierra, many Finder aliases appear as generic document icons rather than as the informative icons that were available in previous versions of OS X.
Is there something I can do to fix this?
It is a bug in 10.12.1, there is no current permanent fix.
It seems to be a Finder refresh issue. If you kill the Finder.app and relaunch it, the normal icon will show up.
