Spotlight bug / Mac App Store When I search for the Keynote app using spotlight there is a reference of a previous version on the Mac App Store. 

 

However, when I press on it, I get the following error message:



Does anyone know how to solve this?
It is likely it is a previous version on your Time Machine drive.

Open system preferences > spotlight > privacy

Drag the Time machine drive into that window so it won't show results from that drive.
