「このアプリケーションで開く」の中身が重複している場合。

More than 5 years have passed since last update.

ファイルを右クリックしてから「このアプリケーションで開く」で、すでに削除済みのアプリや同じアプリが重複して表示されている場合、下記の対応で解消可能。

ターミナルから

$ /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain user
$ killall Finder

自分の場合、最初のコマンドを実行してから長時間応答がなかったため、control+cでキャンセルして、Macを再起動してから再度実行したらうまくいった。
