yosemite no finder preferences
I have just installed the Yosemite upgrade on both my iMacs. One is working fine. However the Finder preferences box on the iMac 3.5 GHy Intel Core 7 is now blank. The General. Tags, Sidebar and advanced are all missing. Have I deleted something by mistake? I tried reloading the upgrade but the same thing happens.
I don't think I need the functionality immediately, but it would be good to get it fixed.
However I also have lost the small window that shows the status of finder copying files. It does copy the file and there is a sound when the action is complete. But there is no widow showing progress or showing when there is a duplicate file etc...
Any help would be appreciated.
iMac, OS X Yosemite (10.10)
