Yesterday I bought my new Mac Book Air and downloaded some apps. I later upgraded to Mac OS High Sierra and when I open a dmg file and drag the icon to Application folder beside it or Desktop, an error pops up saying

"The operation can’t be completed because one or more required items can’t be found.

(Error code -43)"

Before upgrade everything worked fine but after upgrade to High Sierra (10.13.1) this started happening.
