I just did some cleaning out of my MacBookAir and the finder window will now not open - have I deleted something I shouldn't have? How do I re-install Finder?
Try double-clicking on your disk icon on the Desktop.
The Finder.app is located in the /System/Library/CoreServices/ folder. I hope you weren't trying to clean out things there.
If double clicking the icon as Kappy suggests doesn't work, or if its not on your desktop...
Click the apple >> force quit >> select finder >> click relaunch. Or try rebooting.
thanks - it seems I am all fixed - thanks again..
