Not sure if anybody else has this, but all of a sudden my icon changed on my mac xls files. xlsx file still have the same icon so not sure what happened.
How do I change the old icon back, which looks more like an xlsx file.
The default application is Microsoft Excel. Just the icons changed....I did get an update yesterday from Apple with the updated security patch. Wonder if that caused problems.
There's a post in that thread with a LaunchServices terminal command, which is the approximate equivalent of the old classic MacOS "rebuilding the desktop database".
