What You Can Change on Your Mac Home Screen

Your Mac home screen is the desktop you see when you start up or minimize all windows. You can change the background image, add or remove icons from the dock, rearrange your desktop layout, and customize how your Mac displays notifications and widgets. The steps differ slightly depending on whether you're using a recent version of macOS (Ventura, Sonoma, or later) or an older one, but the core process is straightforward and doesn't require any special tools.

Most changes happen through System Settings, which is the control center for your Mac's appearance and behavior. You don't need to restart your Mac or install anything—changes take effect when ready.

Key Takeaways

  • Open System Settings, click Wallpaper, and select a new background image from Apple's library or upload your own photo.
  • The dock—the row of icons at the bottom of your screen—can be customized by dragging icons out to remove them or dragging new ones in from your Applications folder.
  • Desktop icons (files and folders on your background) can be moved by clicking and dragging them, or hidden entirely through View options.
  • Notification Center and widgets appear on the right side of your screen in recent macOS versions and can be toggled on or off in System Settings.

How to Change Your Desktop Background Image

Open System Settings by clicking the Apple menu in the top-left corner, then selecting System Settings. Click the Wallpaper option in the left sidebar. You'll see a grid of built-in images organized by category—Dynamic, Light, Dark, Collections, and more. Click any image to preview it, then click Set Desktop to explore it.

To use your own photo, click the plus button at the bottom of the Wallpaper window, navigate to the image file on your Mac, and click Open. The image will be added to your custom wallpapers and applied when ready. If the image doesn't fill your screen properly, right-click it in the Wallpaper window and choose a scaling option like "Fit" or "Fill" to adjust how it displays.

Customizing Your Dock

The dock is the row of process icons that appears at the bottom of your screen by default. To remove an icon from the dock, right-click it and select Remove from Dock. To add an icon, open Finder, click Applications in the sidebar, find the app you want, and drag it directly onto the dock. You can also drag dock icons left or right to reorder them.

To hide the dock when you're not using it, open System Settings, click General in the left sidebar, scroll down to Dock, and toggle on "Automatically hide and show the Dock." The dock will slide out of view and reappear when you move your cursor to the bottom of the screen. You can also change the dock's size by going to System Settings > General > Dock and adjusting the Size slider.

Managing Desktop Icons and Files

Files and folders you save to your desktop appear as icons on your home screen. To move them, click and drag them to a new position. To delete them, right-click and select Move to Trash. If your desktop feels cluttered, you can hide all desktop icons by opening Finder, clicking the desktop to make sure it's active, then pressing Command+J to open View Options. Uncheck "Show icons" and click the close button.

You can also organize desktop icons into groups by right-clicking the desktop, hovering over Sort By, and selecting a sorting method like Name, Kind, or Date Modified. This automatically arranges your icons without you having to move them manually.

Adding and Removing Widgets and Notification Center

In macOS Ventura and later, the Notification Center and widgets appear on the right side of your screen. To add a widget, click the plus button at the top of the Notification Center panel, search for the app you want a widget for, and click Add Widget. Common widgets include Weather, Calendar, Stocks, and Reminders. You can remove a widget by clicking and holding it, then selecting Remove Widget.

To hide the Notification Center entirely, open System Settings, click Control Center in the left sidebar, and toggle off "Show in menu bar." The panel will no longer appear on the right side of your screen, though you can still access notifications through other means.

Changing Display and Appearance Settings

Beyond the background image, you can change how your Mac looks overall. Open System Settings and click Appearance in the left sidebar. Choose between Light, Dark, or Auto (which switches based on time of day). You can also select an accent color that appears in buttons, highlights, and other interface elements throughout macOS.

If you want to change the size of text and icons across your entire Mac, go to System Settings > Displays and look for the Resolution or Scaled option. Choosing a lower resolution makes everything larger; choosing a higher resolution makes everything smaller. Changes take effect when ready, though some apps may need to be restarted to display correctly.

Organizing with Spaces and Mission Control

If you work with many windows at once, you can create separate virtual desktops called Spaces. Swipe up with four fingers on your trackpad to open Mission Control, which shows all your open windows and Spaces. Click the plus button in the top-right corner to add a new Space. You can then drag windows between Spaces or use Control+Arrow keys to switch between them.

This feature is useful if you want to keep work-related windows on one Space and personal windows on another, keeping your home screen less cluttered. You can also set up Hot Corners—areas of your screen that trigger actions when you move your cursor to them—by going to System Settings > General > Desktop & Dock and scrolling down to Hot Corners.

Frequently Asked Questions

Can I use a photo from the internet as my desktop background?

Yes. Right-click the image in your web browser, select Save Image As, choose a location on your Mac, and click Save. Then open System Settings > Wallpaper, click the plus button, and select the image file you just saved.

Why does my desktop background look blurry or stretched?

The image size doesn't match your screen resolution. Right-click the wallpaper in System Settings, select a different scaling option like "Fit" or "Fill," and see which one looks best. "Fill" crops the image to fit; "Fit" shrinks it to show the whole image.

How do I get the dock back if I accidentally hid it?

Move your cursor to the bottom edge of your screen where the dock normally appears, and it will slide out. Then open System Settings > General > Dock and toggle off "Automatically hide and show the Dock" to make it stay visible.

Can I have different backgrounds on each Space?

Yes. Open Mission Control, right-click the Space you want to customize, and select Manage Spaces. Then set a different wallpaper for each Space through System Settings > Wallpaper.

What's the difference between the dock and the Applications folder?

The dock is a shortcut bar for apps you use frequently. The Applications folder contains every app installed on your Mac. You don't need to put every app in the dock—only the ones you use regularly.
