macOS Sidebar vs Dock: When to Use Each

If you’re deep in the Apple ecosystem, you’ve probably seen both the Dock and Sidebar in macOS — but what’s the difference? And when should you use one over the other?
In this post, we’ll break down the Sidebar vs Dock debate and introduce a third, more flexible option for power users: the ExtraDock.
🧭 What is the macOS Dock?
The Dock is Apple’s launcher that sits at the bottom (or side) of your screen. It’s used for:
- Launching frequently used apps
- Switching between open applications
- Accessing folders like Downloads or the Trash
It’s fixed in position, only appears on one monitor at a time, and can’t be duplicated.
Pros:
✅ Fast access to pinned apps ✅ Supports drag-and-drop to open files ✅ Always visible (if you want it)
Cons:
❌ Only one Dock at a time ❌ Moves between monitors ❌ Limited customization
📁 What is the Sidebar in macOS?
The Sidebar appears in Finder windows and certain apps. It helps you:
- Navigate folders, drives, or cloud storage
- Quickly access recent files
- Bookmark frequently-used locations
Think of it as a file-focused navigator, not a launcher.
Pros:
✅ Great for file management ✅ Works well with Finder workflows ✅ Fully customizable folder list
Cons:
❌ Not global — only inside apps like Finder ❌ No app launching or multitasking help ❌ Can’t be placed freely
🧠 Sidebar vs Dock: Which Should You Use?
Feature | Dock | Sidebar |
---|---|---|
App launching | ✅ Yes | ❌ No |
File/folder navigation | ❌ Limited | ✅ Yes |
Floating / free placement | ❌ No | ❌ No |
Multi-monitor support | ❌ Limited | ❌ No |
Custom layouts | ❌ Limited | ✅ Kinda |
They both serve a purpose — but if you want ultimate control over how your tools are laid out across screens…
