Mac Dock をコントロール

システムを変更せずに Mac Dock がディスプレイ間を移動するのを防ぐ世界初のアプリです。

Dock を好みの画面に固定し、画面共有中も安定させ、スリープ解除、ディスプレイ変更、接続イベント後も賢く動作させます。

OS X Mavericks 10.9 以降に対応しています。この問題が長く放置されてきたことへの小さな抗議でもあります。DockLock は影響を受けるすべての macOS 世代で Dock の移動問題を解決します。

! 問題

ポインタを見失うと、見つけるまでマウスを動かすのが自然です。複数ディスプレイの Mac では、その動きが別の画面の下端に触れて、Dock が意図しないディスプレイへ移動することがあります。

  • 作業を止めて Dock を元に戻す必要があります。
  • macOS が Dock のために影響を受けた画面のウィンドウサイズを変更します。
  • 画面いっぱいの高さで配置したウィンドウを毎回手動で直すことがあります。

解決策

DockLock は Dock の位置を守るためにバックグラウンドで継続的に動作します。スリープ解除、ディスプレイ変更、接続イベントを検知し、Dock をワークフローが期待する画面へ自動的に戻します。

  • スリープ解除や画面変更後に Dock を自動で戻します。
  • システムファイルのパッチも SIP の変更もありません。
  • ローカル設定を使うプライバシー優先設計です。
  • アクセシビリティ権限は Dock 管理にのみ使用します。

Pro プロトタイプは固定を超えます。実行中の本物の macOS Dock を制御し、サイド位置に対応し、縦 Dock を任意のディスプレイへ移動し、ウィンドウのために Dock 周辺の空間を解放します。永続的なシステム設定を書き込まず、SIP を無効にする必要もありません。

DockLock Plus を自動化

DockLock Plus は Apple ショートカット、URL スキーム呼び出し、ターミナルスクリプト、Siri、Raycast と統合し、Dock が作業を妨げるのではなくワークフローに従うようにします。

なぜ存在するのか

Mac で複数モニターを使うと、カーソルが別の画面端に触れた瞬間に Dock が移動することがあります。DockLock は一度きりの小技ではありません。Dock の安定性をプロ品質の信頼性で継続的に守るバックグラウンドサービスです。

開発者、デザイナー、発表者、配信者、そして画面間を移動しても安定したデスクトップを望むすべての人に役立ちます。

独立開発者が制作

DockLock は、本当の代替手段がない問題を数か月調査したことから始まりました。必要な道具が存在しなかったために作られた、同種初のアプリです。

DockLock は Ihor July が一人で 900 時間以上かけてリバースエンジニアリング、開発、テストした成果です。すべての購入が、保守、将来の macOS 対応、Apple が作らなかった独創的なツールを支えます。

私の焦点はコピーではなく、独創的な macOS ユーティリティです。DockLock を支援すると、同種初のアプリがさらに生まれます。発明せずコピーする仕事を支援すると、増えるのはコピーだけです。

DockLock アプリは性能のためにネイティブ C++ で作られ、設定はローカルに保存され、Mac App Store 版ではバックグラウンドのネットワーク要求を行いません。

DockLock が購入されるのは、この問題が現実で、古く、現代のマルチディスプレイ Mac でもまだ作業を妨げるからです。

We need more indy developers like this

Hands down, one of the best utilities that I came across for MacOS. First thing I install on a new Mac.

2 screens and no hassle.

I run a MBP with an external screen and I was tired of constantly fighting with the dock settings… This app made it invisible !

This is game changer

I'm multi display user and that jumping dock was bothering me since begining of my mac journey. I was forced to use dock on the side which i'm not a fan of because it's far away to the left on my setup and can't fit that much icons as horizontal bottom dock. So thanks to this app I can finally use dock on the bottom, after 8 years of struggle and hoping for fix on every macos release each year. Thank you very much!

Great value considering how much time it saves. Highly recommended!

I've been using dual (and sometimes triple) monitors with macOS for years, and the Dock constantly jumping to whichever screen I brushed the bottom edge of was a real productivity killer. Since I installed DockLock Lite, that annoyance is gone: the Dock stays exactly where I set it on my preferred screen, even when I'm juggling full‑screen apps and screen sharing... The dev is quick to respond to feedback and has already fixed some stability bugs in recent updates.

Perfect while sharing a monitor

I like this app especially when using Teams and sharing my second monitor 1) People don't get to see the dock 2) They also don't see - while I Command-Tab - the apps I have open

Finally, a solution to one of the most annoying things on MacOS!

If you use a Mac with multiple monitors, DockLock Plus is the essential app you never knew you needed. For years, macOS users have struggled with the Dock unpredictably jumping between screens-a persistent annoyance that Apple never addressed. DockLock Plus finally delivers the seamless, frustration-free multi-monitor experience professionals have been waiting for.

Exceptional tool for an annoying problem

At first glance it might seem that the app pricing is a bit high for "just" keeping the dock locked until you realize that 1. Apple has not fixed this in years. 2. If you have multiple monitors your productivity exceeds the cost of the app. Fantastic tool, does what it advertises and the developer is super responsive and very very helpful.

Do you struggle with your Dock staying put?

Do you struggle with your Dock staying put? If the answer is no, this app isn't for you. But if you've contracted a case of multiple monitors, beware: You're at risk to experience Apple's most hateful "feature", how the Dock hurdles itself to another display the moment your mouse innocently brushes the bottom of another screen like an overeager golden retriever chasing a ball. It's annoying. It's disruptive. It's like macOS is personally attempting to sabotage your carefully arranged windows just to watch your productivity suffer. Thankfully, DockLock Plus has solved this. And for a not unreasonable amount of money, ether. Just buy it. Your windows stay arranged, your workflow stays intact, and you'll have a shred more sanity.

Works perfectly as described

I was searching for something like this for a long time hoping every year Apple would provide this feature out of the box in the new OS but I was disappointed. Until I found this. No more annoying unintended dock appearances on other screens. My favorite part is once you hide the menu bar icon and remove icon from dock, and enable at startup, you simply would never know if something like this exists. Works like a charm

Much Needed Solution to Nuisance Issue

This solves one of those "Why isn't this a native feature of MacOS?" issues. I use a 3 monitor setup...2 large monitors side by side, plus my MBP display below. My dock was having an identity crisis deciding where to live. I wanted it on a specific monitor and not be vertical. I tried various suggestions found online, but this app did what fiddling around with settings couldn't. An elegant solution with plenty of configuration options. I can now force the dock to stay on one specific monitor, or I can allow it to bounce between just the external monitors while avoiding the build in display, or various other combinations. Thank you!

Fantastic!

Works as advertised! I've been trying to fix this problem for so long. Just a note, this works for docking stations too. Not sure if that's clearly stated anywhere. My docking station uses a DisplayLink driver and it all still works. Bravo!

Finally the dock works as it should!

So many years waiting for Apple to fix this. Now I can finally rest the dock on the bottom of my laptop's screen without it moving to the external screen, which happens frequently when placing the dock at the bottom and using the external screen on top of the smaller one (which is the best way to use it, IMHO, when you want to use both a small one from the laptop and a big one). This paid version allows dockLock to work with the dock hidden, which is also my preferred way to use it - but so impractical when we couldn't prevent it to be moved to the external screen. Works like a charm.

Best quality of life app EVER!

It blows my mind that this is not something that is natively able to be done on via the Mac's internal interface. However, this app is the BEST! A lot of the software I am using requires my mouse to be almost at the bottom of the screen, which would always cause the Dock to jump in the way of what I was working on. I love that I can set it on the single screen that I want it on (out of the 4 monitors I am using) and it no longer gets in the way. My productivity has increased. Everyone who has a Mac needs this app!

Every single Mac should automatically come with this app pre-installed

The Mac Dock's random jumping between screens has been a persistent source of frustration for countless macOS users over the years. It occurs frequently, disrupting focus and productivity during work. Despite numerous complaints, Apple has consistently disregarded customer feedback. To address this issue, Apple should acquire DockLock, ensuring its pre-installation on every Mac. DockLock is not a luxury but a necessity, and its inclusion would significantly enhance the user experience.

Hurrah!

Working with two monitors just got so much better! No more accidentally moving the cursor to the bottom of the second screen and watching the Dock unexpectedly jump over. The bottom edge of my secondary screen is no longer a danger zone 😂. At the same time, if I do want to move the Dock, I can do it easily with a special key, or even lock it to the secondary monitor if that's what I prefer. Finally, I feel in control! 💪

Work very well

My setup is 2-monitor vertically stacked: main 5K monitor and an iPad Pro 13 just below it, with wired sidecar. The jumping dock has always been a nuisance. With this App, the dock stays on main monitor when sidecar is off, and stays on sidecar iPad as soon as I connect it. Perfect. Immediately bought the plus version. Well done!

Indispensable

This is a small and really nice utility. If you work with multiple monitors, you tend to keep your Dock at the bottom of the screen. MacOS has this unnerving feature that, once you hit the bottom part of any screen with the mouse, it will move the Dock to that screen. This utility will stop MacOS from doing that every time. I waited a long time for a utility like this! Thumbs up!!

Finally we have a solution!

After years of struggling with this issue specially during screen sharing where the dock would just pop up when hovering over screen bottom, I am happy to say we have a fix in the form of DockLock. I had written feedback to apple numerous times on how annoying this was & they should fix it.
