Switching from Windows to Mac: The Complete Beginner's Guide (2026)

Your first days on a Mac after Windows are one long "wait, where's...". Where's the Start menu and the C: drive, why did the window close while the app kept running, how do you install something without an installer, and why doesn't Alt+Shift switch the language.

This guide covers everything worth knowing and setting up in your first week, in order: what replaces what, then apps, files, the keyboard and language switching. No "magic of the ecosystem" - just the practical parts.

What replaces what: Windows to Mac

Windows	Mac
Start menu	Spotlight (Cmd+Space) and the Applications folder
Taskbar	The Dock - the strip of icons at the bottom of the screen
System tray	The right side of the menu bar at the top of the screen
File Explorer	Finder
Control Panel, Settings	System Settings
Task Manager	Activity Monitor
Ctrl+Alt+Del	Cmd+Option+Esc - Force Quit
Snipping Tool, Win+Shift+S	Cmd+Shift+5 or Cmd+Shift+4
Notepad	TextEdit
Paint, Photos for quick edits	Preview - crop, resize, sign PDFs
.exe installer	A .dmg file or the App Store
C: drive	Your home folder and Macintosh HD
Windows Defender	macOS built-in protection
Alt+Shift, Win+Space	Ctrl+Space or the 🌐 Globe key

The fastest way to find anything on a Mac is Spotlight: Cmd+Space, a few letters, Return. It opens apps, files, and settings, and even does math. For a former Start-menu user, it's habit number one.

The big difference: the app menu lives at the top of the screen

On Windows, every window has its own menu. On a Mac there's one menu - in the menu bar at the top of the screen - and it belongs to whichever app is active. Click a Chrome window and the top menu is Chrome's. Click the desktop and it's Finder's.

Two items exist in almost every app's menu, under the app's name on the left:

• Settings (sometimes "Preferences") - open it with Cmd+, in any app.
• Quit - Cmd+Q.

Closing a window is not quitting the app

The red button in the corner of a window closes the window, not the app. The app keeps running - you'll see a dot under its icon in the Dock. That's normal on a Mac: keeping mail, chat, and the browser open with no windows is common, and the system manages memory on its own.

To quit an app completely, press Cmd+Q or right-click its Dock icon → Quit.

The window buttons are on the left, not the right, and there are three:

• Red - close the window.
• Yellow - minimize to the Dock (Cmd+M).
• Green - full screen. Hover over it and you get a menu to tile the window to the left or right half of the screen, or next to another window.

On macOS 15 and later, windows snap to screen edges like Windows Snap: drag a window to the edge, or press Fn+Ctrl+← or Fn+Ctrl+→. To fill the screen without going full screen, press Fn+Ctrl+F.

The Win+Tab equivalent is Mission Control: swipe up with three fingers on the trackpad or press Ctrl+↑ to see every open window at once.

How to install and uninstall apps

There are almost no "Next → Next → Finish" installers on a Mac. You get three options:

1. App Store - like the store on your phone: find it, click Get, done.
2. A .dmg file - the most common way for apps downloaded from websites. Open the .dmg, and you'll see the app's icon - drag it into the Applications folder. Then eject the disk image (right-click → Eject) and delete the .dmg.
3. A .pkg file - a regular step-by-step installer, like on Windows. Less common.

The first time you open an app from the web, macOS asks whether you're sure - that's normal. If it says it can't verify the developer, open System Settings → Privacy & Security, scroll down, and click Open Anyway for that app. The old right-click → Open trick no longer works on recent macOS versions.

Some utilities ask for extra permissions - keyboard access, screen recording, files. Those are switched on in the same place, Privacy & Security. Only grant them to apps you trust.

To uninstall an app, drag it from Applications to the Trash and empty the Trash. There's no "Add or Remove Programs". If an app ships its own uninstaller, use that instead.

How to move your files from Windows to Mac

Migration Assistant. Apple has a free tool for moving from Windows: install Windows Migration Assistant from Apple's website on the PC, and run Migration Assistant on the Mac (Applications → Utilities). Both computers need to be on the same Wi-Fi network. It moves your documents, photos, browser bookmarks, and some settings.

Cloud. OneDrive, Google Drive, Dropbox, and iCloud all have Mac apps. If your files are already in the cloud, install the client and sign in.

External drive or USB stick. Here's the trap: a Mac reads NTFS drives (the Windows standard) but can't write to them. You can copy files off such a drive, but not back onto it. For a drive you'll use with both systems, pick exFAT - both Windows and macOS read and write it. You can reformat it in Disk Utility, but that erases everything on the drive.

Apps: what works and what to replace

Most popular software has a Mac version: Chrome, Firefox, Edge, Zoom, Slack, Teams, Spotify, WhatsApp, Telegram, Microsoft Office, Adobe. They work the same - just with Cmd instead of Ctrl in shortcuts.

The Mac also comes with free built-in apps that cover a lot:

• Pages, Numbers, Keynote - the Word, Excel, and PowerPoint equivalents. They open and save .docx, .xlsx, and .pptx files.
• Preview - PDFs and images: sign a document, merge PDFs, crop or resize photos.
• Quick Look - select a file in Finder and press Space to view it without opening it.
• .zip archives open with a double-click. For .rar, get the free The Unarchiver from the App Store.

Windows-only software (some accounting, engineering, and industry-specific tools) won't run on a Mac directly. Your options are a web version if one exists, or Windows in a virtual machine - Parallels Desktop runs Windows 11 on Apple silicon Macs. Boot Camp, which used to install Windows as a second system, is only available on older Intel Macs.

Games are their own story: some come out on Mac, many don't. Check yours before you switch.

Keyboard: Ctrl becomes Cmd

The main rule: most Windows shortcuts with Ctrl work on a Mac with Cmd (⌘). The ones you'll need on day one:

Windows	Mac	What it does
Ctrl+C / Ctrl+V / Ctrl+Z	Cmd+C / Cmd+V / Cmd+Z	Copy / paste / undo
Alt+Tab	Cmd+Tab	Switch apps
Alt+F4	Cmd+Q (more)	Quit the app
Home / End	Cmd+← / Cmd+→	Start / end of line
Backspace	Delete	Delete to the left
Delete	Fn+Delete	Delete to the right
F2 in Explorer	Return in Finder	Rename a file
PrtSc	Cmd+Shift+3	Screenshot of the whole screen

The full tables - text and cursor, windows, Finder, browser, screenshots - are in Mac keyboard shortcuts for Windows users.

Two more things that trip everyone up. The top row on a Mac keyboard controls brightness and volume - for F1-F12, hold Fn. And if you plug in a Windows keyboard, its Alt key acts as Option and the Windows key as Cmd. To get Cmd next to the space bar like on a Mac, swap Option and Command in System Settings → Keyboard → Keyboard Shortcuts… → Modifier Keys.

Language and keyboard layout: where everyone stumbles

On Windows you switch input language with Alt+Shift or Win+Space. On a Mac the default is Ctrl+Space or the 🌐 Globe key on newer Apple keyboards. You can also switch with Caps Lock.

macOS won't let you set Alt+Shift itself - it doesn't accept a combination made only of modifier keys. But you can pick any other combination: here's how to change the keyboard layout shortcut, and all the ways to switch keyboard language on a Mac.

Which layout to add. Add a second language in System Settings → Keyboard → Input Sources → Edit → +. Many languages come in several variants on a Mac, and the one that matches your Windows layout is often labeled "– PC" - for example, British – PC or French – PC. Pick that one and your muscle memory moves with you. Then turn on "Show Input menu in menu bar" so you always see which language you're typing in.

The Mac switches language on its own. If your layout seems to jump when you move between windows, it's a setting that remembers the input source per document. Here's how to turn it off, plus four other causes: Mac keeps switching keyboard language.

The layout-switcher habit. If you used Punto Switcher or a similar tool on Windows, it's the first thing you'll look for on a Mac - and you won't find it: Punto Switcher for Mac is gone.

That's why we made Boomkey. When text comes out in the wrong layout, select it and double-tap Shift - it converts to the layout you meant, between any two layouts you have installed. It's a native menu bar app, everything runs locally on your Mac, one-time purchase with a 7-day trial - no card, no account.

Trackpad and mouse

• Right-click - click or tap with two fingers, or Ctrl+click.
• Tap to click. By default you have to press the trackpad down. To click with a light tap, like most Windows laptops, turn it on in System Settings → Trackpad.
• "Reversed" scrolling. On a Mac, content follows your fingers like on a phone, so a mouse wheel scrolls the opposite way from Windows. Turn off Natural scrolling in the Trackpad or Mouse settings. Note that macOS uses one setting for both devices.
• Gestures. Three fingers up for all windows, three fingers left or right to switch desktops, pinch to zoom. Every gesture has a video demo in the Trackpad settings.

Files and Finder: where's the C: drive

There are no drive letters on a Mac. Your files live in your home folder (Cmd+Shift+H in Finder): Desktop, Documents, Downloads, Pictures. The system drive is called Macintosh HD, and you rarely need to go in there.

What to set up in Finder right away:

• File extensions. macOS hides some extensions by default. Turn on Finder → Settings → Advanced → "Show all filename extensions".
• Path bar. To see which folder you're in, like the Explorer address bar, press Cmd+Option+P.
• Cut and paste. There's no Ctrl+X for files. Copy with Cmd+C, then move with Cmd+Option+V.
• Hidden files - Cmd+Shift+.

10 settings to change on day one

1. Add your second keyboard language and turn on "Show Input menu in menu bar".
2. Pick a comfortable language switch: Ctrl+Space, 🌐, Caps Lock, or your own combination.
3. F1-F12 as standard function keys, if you use them more than brightness: System Settings → Keyboard → Keyboard Shortcuts… → Function Keys.
4. Tap to click on the trackpad.
5. Scroll direction - if "natural" never starts feeling natural.
6. File extensions in Finder.
7. Path bar in Finder.
8. Default browser - in System Settings → Desktop & Dock.
9. Clean up the Dock: drag an icon you don't need up out of the Dock and let go.
10. Time Machine backups to an external drive - built in, set up once, then it runs on its own.

How long it takes to get used to a Mac

The first week is the hardest: your fingers press Ctrl, Alt+Shift, and Home, and windows close "wrong". After that it gets easier - Cmd instead of Ctrl sticks quickly, and within a few weeks most habits rewire themselves. The keyboard layout is what lingers longest, so set it up the way you like right away instead of putting up with it.

FAQ

Is it hard to switch from Windows to Mac? The first week is the hardest, while you get used to Cmd instead of Ctrl, the menu at the top of the screen, and a different language switch. Most apps are the same, and the basics on a Mac work the same way or simpler.

Can I run Windows programs on a Mac? .exe files don't run on a Mac directly. Most popular programs have a Mac version, and Windows-only software can run in a virtual machine such as Parallels Desktop.

Can I install Windows on a Mac? On Apple silicon Macs, only in a virtual machine: Parallels Desktop runs Windows 11. Boot Camp, which installs Windows as a second system, is only available on older Intel Macs.

How do I transfer files from Windows to Mac? The simplest way is Migration Assistant: install Windows Migration Assistant from Apple's website on the PC, run Migration Assistant on the Mac, with both on the same network. Other options are the cloud (OneDrive, Google Drive, iCloud) or an external drive.

Why can't my Mac write to my USB drive? Most likely the drive is formatted as NTFS: a Mac reads it but can't write to it. For a drive you use with both systems, use exFAT - both Windows and macOS support it.

How do I uninstall an app on a Mac? Drag it from the Applications folder to the Trash and empty the Trash. If the app has its own uninstaller, use that instead.

How do I switch keyboard language on a Mac, like Alt+Shift on Windows? By default it's Ctrl+Space or the 🌐 Globe key. macOS won't let you set Alt+Shift itself, but you can choose another combination or switch with Caps Lock.

Do I need antivirus on a Mac? For most people, no: macOS has built-in malware protection that updates automatically. Install apps from the App Store or developers' official websites, and keep the system up to date.
