Mac Basics for Windows Users Switching Over

Switching from Windows to a Mac feels strange at first, but most tasks have a close equivalent. The layout is different, the Command key takes the place of Ctrl, and the menu bar sits at the top of the screen. This guide covers the differences that cause the most confusion in the first week.

The Command key

Where Windows uses Ctrl for copy, paste and save, macOS uses Command (⌘). Most shortcuts you know still work with Command in place of Ctrl. The Option key takes the role of Alt, and Control is used less often, mainly for right-clicking in some apps.

The menu bar and Dock

In macOS, the menu bar is at the top of the screen and always shows the menus for the active app. The Dock at the bottom holds favourite apps and running apps. Windows keeps each window's menu inside the window, so the first few days can feel untidy until you get used to it.

Finder instead of File Explorer

Finder is the file manager. Open it from the Dock. Press Command + Shift + G to type a folder path, and Command + Delete to move a file to the Trash. Empty the Trash to free space. Use Command + Space to open Spotlight, the search tool, and type the name of an app or file.

Closing windows and quitting apps

Clicking the red close button closes a window, but the app keeps running in the Dock. Press Command + Q to quit the app completely. This surprises many Windows users, because closing the last window does not always quit the program.

Installing apps

Most apps come as a disk image (.dmg). Open it and drag the app into the Applications folder.
Apps from the Mac App Store update themselves through the App Store.
Install only apps from official developer websites or the App Store.

Screenshots and the clipboard

Command + Shift + 4 captures a selected area, and Command + Shift + 3 captures the whole screen. Screenshots save to the desktop by default. Command + Shift + 5 opens the screenshot toolbar with recording options.

Keyboard and trackpad habits

The trackpad gestures are different. Swipe with two fingers to scroll, and use three fingers to swipe between full-screen apps or open Mission Control. Right-click with two fingers, or tap the trackpad with two fingers. You can change these gestures in System Settings under Trackpad.

Frequently asked questions

Does my Windows software run on a Mac?

Many Windows programs have Mac versions. Some do not. Check the developer's website before you buy. You can also use a virtual machine or a remote desktop for Windows-only programs.

Do Macs need antivirus software?

macOS includes protection, but keeping the system updated and installing software only from trusted sources matters just as much. See what malware is and how to remove it.

Use Spotlight and Launchpad

Spotlight is the fastest way to open apps and find files on a Mac. Press Command + Space, type the first few letters and press Enter. If you prefer a grid of icons, Launchpad shows every installed app. Many former Windows users keep a few apps in the Dock and rely on Spotlight for everything else, which keeps the desktop uncluttered.

Window management without a mouse

macOS has built-in tiling in recent versions. Drag a window to the edge of the screen to fill half, or hold the green button to choose a layout. Mission Control, opened with a three-finger swipe up or the F3 key, shows all open windows and desktops at once. Learning these shortcuts reduces the number of clicks needed to arrange your work.

Common problems in the first week

New Mac users often find that the Delete key does not delete forward and that the Home and End keys behave differently. Use Fn + Delete for forward delete, and Command + Left or Right to jump to the start or end of a line. If an app will not install, check System Settings under Privacy and Security, because macOS may need your approval for apps from outside the App Store.
