Mac OS High Sierra で Launchpad をリセットする

アプリのインストール・アンインストールを繰り返していると、次第に Launchpad との間にずれができてくる。ちなみに Launchpad はこのアイコンで、インストールされているアプリの一覧が見られるものだ。

消したはずのアプリがいつまでも残っていたので、まずは Finder から修正を試みた。まずはこの Apple Support を参考に、Home/Library/Application Support/Dock/ の中を覗いてみる。

desktoppicture.db と、長い数字.db という二つのデータベースファイルがある。長い数字の方を削除(一応デスクトップにバックアップ)して再起動するが、Launchpad に変化はない。サポートページにあるように 8x-4x-4x-4x-12x.db というファイル名ではないので、たぶん OS による違いだろう。

Terminal で Application Support 内を見てみたが、あまり意味はなかった。ターミナルでは、Application Support のスペースはバックスラッシュで記載する。

そこで、このページ に載っていた以下のコマンドをターミナルで実行。

defaults write com.apple.dock ResetLaunchPad -bool true; killall Dock

これがうまく動いた。なんだか Mac の動きも軽快になった気がする。定期的にリセットしたほうがいいのかもしれない。

I think what you composed made a ton of sense. But, think on this, suppose you were to write a awesome headline?
I ain't saying your content is not solid, but what if you added a headline
that makes people desire more? I mean Mac OS High Sierra で Launchpad をリセットする -
UB's tweets is a little vanilla. You could peek at Yahoo's
front page and see how they write article titles to get viewers interested.
You might add a video or a picture or two to grab people excited about everything've
written. In my opinion, it might bring your blog a little bit more interesting.
