How to Use Windows Apps and Services on a Mac

Running Windows software on a Mac used to mean rebooting into Boot Camp or keeping a second PC around. Today, you can open Windows apps side by side with your macOS apps, access Windows-only services, and even run legacy software without leaving your desktop. This guide covers the main methods—from free built-in tools to paid virtualization—and walks you through setting each one up, so you can pick the approach that fits your hardware and workflow.

What You’ll Need

• A Mac with an Intel processor or Apple silicon (M1/M2/M3/M4). The method you choose depends on the chip.
• Enough free storage space—Windows itself takes about 20–30 GB, plus room for your apps and files.
• At least 8 GB of RAM (16 GB recommended for smoother performance).
• A Windows license (product key) if you plan to install Windows via Boot Camp or a virtual machine. Some methods like CrossOver or Wine don’t require a Windows license.
• An internet connection to download the necessary software and Windows installation files.

Step-by-Step

Method 1: Use a Virtual Machine (Parallels Desktop, VMware Fusion, UTM)

Virtualization runs Windows as an app inside macOS. It’s the most flexible for running multiple Windows apps alongside Mac apps.

1. Choose a virtualization app. Parallels Desktop is the most user-friendly but paid. VMware Fusion is free for personal use. UTM is free and open-source, and works well on both Intel and Apple silicon.
2. Download the Windows ISO. Go to Microsoft’s official Windows 11 download page and download the ISO file. You’ll need a valid license key to activate, but you can install without one initially.
3. Install the virtualization app. Open the downloaded .dmg file and drag the app to your Applications folder. Launch it.
4. Create a new virtual machine. In the app, choose “New” or “Create a VM.” Select “Install Windows from an ISO” and point to the downloaded ISO.
5. Configure resources. Allocate at least 4 GB of RAM and 2 CPU cores (more if your Mac has spare capacity). Set the disk size to at least 60 GB (it will only use what Windows actually occupies).
6. Start the installation. The VM will boot from the ISO. Follow the Windows setup prompts. When asked for a product key, you can select “I don’t have a product key” to continue.
7. Install the integration tools. For Parallels, install “Parallels Tools”; for VMware, install “VMware Tools”; for UTM, install “SPICE Guest Tools.” These drivers make the mouse, graphics, and clipboard work smoothly.
8. Use your Windows apps. Once Windows is running, you can install any software just as you would on a PC. You can also set the VM to run in “Coherence” (Parallels) or “Unity” (VMware) so Windows apps appear without the Windows desktop.

Method 2: Use Boot Camp (Intel Macs Only)

Boot Camp lets you install Windows natively on a separate partition. It gives full performance but requires a restart to switch between macOS and Windows.

1. Check your Mac. Boot Camp Assistant is only available on Intel Macs. Apple silicon Macs do not support Boot Camp.
2. Back up your data. Partitioning your drive carries a small risk. Use Time Machine to back up before proceeding.
3. Open Boot Camp Assistant. Find it in Applications > Utilities. Click Continue.
4. Select the Windows ISO. You’ll need to download the Windows 10 or Windows 11 ISO from Microsoft first.
5. Partition your drive. Drag the divider to set the Windows partition size. Microsoft recommends at least 64 GB. Click Install.
6. Follow Windows setup. Your Mac will restart into the Windows installer. Choose the partition labeled “BOOTCAMP” and format it (if prompted).
7. Install Boot Camp drivers. After Windows finishes installing, a window will appear to install Apple’s drivers for Wi-Fi, graphics, and trackpad. Follow the prompts and restart.
8. Switch between operating systems. Hold the Option key at startup to choose macOS or Windows, or set the default in System Preferences > Startup Disk (macOS) or Boot Camp Control Panel (Windows).

Method 3: Use a Compatibility Layer (CrossOver, Wine, Whisky)

These tools translate Windows API calls to macOS, so you can run many Windows apps without installing Windows at all. They work on both Intel and Apple silicon, but not all apps are compatible.

1. Install CrossOver (paid) or Whisky (free). CrossOver has a free trial; Whisky is free and uses Apple’s Game Porting Toolkit.
2. Open the app. For CrossOver, click “Install a Windows Application.” For Whisky, create a new “bottle” (a virtual Windows environment).
3. Search for your app. The app will show a list of supported software. If your app isn’t listed, you can try installing it manually by selecting “Unlisted Application.”
4. Install the app. Follow the prompts. You may need to provide the installer file (.exe) if it’s not downloaded automatically.
5. Launch the app. Once installed, it will appear in the CrossOver or Whisky interface. Double-click to run it. Some apps may require additional configuration, like setting a specific Windows version.

Method 4: Use Remote Desktop (Windows PC Required)

If you already have a Windows PC on your network, you can access its apps and services from your Mac without installing anything locally.

1. Enable Remote Desktop on your Windows PC. Go to Settings > System > Remote Desktop and turn it on. Note the PC name.
2. Download the Microsoft Remote Desktop app from the Mac App Store.
3. Add a PC. Open the app, click “Add PC,” and enter the PC’s name or IP address. You can also add a user account.
4. Connect. Double-click the PC to connect. You’ll see the Windows desktop. You can run any app installed on that PC. The performance depends on your network speed.

Common Mistakes

• Choosing the wrong method for your Mac. Trying to use Boot Camp on Apple silicon won’t work. Always check compatibility first.
• Not allocating enough RAM or disk space. Windows 11 needs at least 4 GB RAM and 64 GB disk. If you allocate less, the VM will be painfully slow or fail to install.
• Skipping the integration tools. Without Parallels Tools or VMware Tools, the VM will have poor graphics, no clipboard sharing, and slow mouse response.
• Forgetting to activate Windows. You can install without a key, but you’ll get a watermark and limited personalization. Use a legitimate key to avoid issues.
• Assuming all apps work in compatibility layers. CrossOver and Whisky support a large catalog, but many apps (especially those with complex DRM) will fail. Check the compatibility database before relying on it.

Tips

• Use a VM for occasional apps. If you only need one or two Windows programs, a VM is simpler than dual-booting.
• Enable “Coherence” or “Unity” mode. This makes Windows apps appear in the Mac dock, so you can use them like native Mac apps.
• Share folders. In virtualization apps, set up shared folders so you can access files from both macOS and Windows without copying.
• Keep Windows updated. Regular updates improve security and compatibility with your Mac’s hardware.
• For gaming, use CrossOver or a VM with GPU passthrough. Boot Camp gives the best performance on Intel Macs, but on Apple silicon, CrossOver or a VM like Parallels with DirectX 11 support is the way to go.

Troubleshooting

• Windows won’t install in a VM. Make sure your Mac meets the minimum requirements and that you’ve allocated enough RAM and disk. Also, check that virtualization is enabled in your Mac’s settings (it is by default).
• Poor performance. Close other apps to free up RAM. Increase the VM’s RAM and CPU allocation. In Parallels, go to the VM’s settings and adjust. For Boot Camp, make sure you installed the Boot Camp drivers.
• No internet in the VM. In the VM settings, check that the network adapter is set to “Shared” or “NAT.” For Boot Camp, reinstall the Boot Camp drivers, especially the Wi-Fi driver.
• Mouse or keyboard not working in VM. Install the integration tools (Parallels Tools, VMware Tools, SPICE Guest Tools). If they’re already installed, restart the VM.
• App crashes in CrossOver. Try a different Windows version in the bottle settings (e.g., Windows 10 instead of Windows 11). Check the CrossOver compatibility database for known workarounds.
• Boot Camp partition not showing in Windows. Open Disk Management (right-click Start > Disk Management) and assign a drive letter to the BOOTCAMP partition.

Frequently Asked Questions

Can I run Windows on an Apple silicon Mac (M1/M2/M3)?

Yes, but not via Boot Camp. Use a virtual machine like Parallels Desktop, VMware Fusion, or UTM, or a compatibility layer like CrossOver or Whisky. These run Windows for ARM, which can emulate x86 apps.

Is it legal to run Windows on a Mac?

Yes, as long as you have a valid Windows license. Microsoft allows running Windows on Macs via virtualization and Boot Camp.

Do I need to buy Windows separately?

Yes, you’ll need a Windows license. You can download the ISO from Microsoft for free, but you’ll need a product key to activate. Some methods like CrossOver don’t require a Windows license because they don’t install Windows itself.

Which method is fastest?

Boot Camp gives the best performance on Intel Macs because Windows runs natively. On Apple silicon, a VM like Parallels is faster than a compatibility layer, but CrossOver can be faster for some games.

Can I access Windows files from macOS?

Yes. In a VM, set up shared folders. In Boot Camp, macOS can read (but not write) NTFS drives by default. You can install third-party tools like Paragon NTFS to enable writing.

Will my Windows apps work with a Mac’s trackpad and keyboard?

Yes, with the integration tools installed. They provide drivers for the trackpad, keyboard, and screen resolution. In Boot Camp, the Boot Camp drivers do the same.
