Install Windows 10 on your Mac with Boot Camp Assistant

With Boot Camp, you can install Microsoft Windows 10 on your Mac, then switch between macOS and Windows when restarting your Mac.

What you need to install Windows 10 on Mac

• MacBook introduced in 2015 or later
• MacBook Air introduced in 2012 or later
• MacBook Pro introduced in 2012 or later
• Mac mini introduced in 2012 or later

64GB or more free storage space on your Mac startup disk:

• Your Mac can have as little as 64GB of free storage space, but at least 128GB of free storage space provides the best experience. Automatic Windows updates require that much space or more.
• If you have an iMac Pro or Mac Pro with 128GB of memory (RAM) or more, your startup disk needs at least as much free storage space as your Mac has memory. 2

An external USB flash drive with a storage capacity of 16GB or more, unless you’re using a Mac that doesn’t need a flash drive to install Windows.

A 64-bit version of Windows 10 Home or Windows 10 Pro on a disk image (ISO) or other installation media. If installing Windows on your Mac for the first time, this must be a full version of Windows, not an upgrade.

• If your copy of Windows came on a USB flash drive, or you have a Windows product key and no installation disc, download a Windows 10 disk image from Microsoft.
• If your copy of Windows came on a DVD, you might need to create a disk image of that DVD.

How to install Windows 10 on Mac

To install Windows, use Boot Camp Assistant, which is included with your Mac.

1. Check your Secure Boot setting

Learn how to check your Secure Boot setting. The default Secure Boot setting is Full Security. If you changed it to No Security, change it back to Full Security before installing Windows. After installing Windows, you can use any Secure Boot setting without affecting your ability to start up from Windows.

2. Use Boot Camp Assistant to create a Windows partition

Open Boot Camp Assistant, which is in the Utilities folder of your Applications folder. Follow the onscreen instructions.

• If you’re asked to insert a USB drive, plug your USB flash drive into your Mac. Boot Camp Assistant will use it to create a bootable USB drive for Windows installation.
• When Boot Camp Assistant asks you to set the size of the Windows partition, remember the minimum storage-space requirements in the previous section. Set a partition size that meets your needs, because you can’t change its size later.

3. Format the Windows (BOOTCAMP) partition

When Boot Camp Assistant finishes, your Mac restarts to the Windows installer. If the installer asks where to install Windows, select the BOOTCAMP partition and click Format. In most cases, the installer selects and formats the BOOTCAMP partition automatically.

4. Install Windows

Unplug any external devices that aren’t necessary during installation. Then click Next and follow the onscreen instructions to begin installing Windows.

5. Use the Boot Camp installer in Windows

After Windows installation completes, your Mac starts up in Windows and opens a ”Welcome to the Boot Camp installer” window. Follow the onscreen instructions to install Boot Camp and Windows support software (drivers). You will be asked to restart when done.

• If the Boot Camp installer never opens, open the Boot Camp installer manually and use it to complete Boot Camp installation.
• If you have an external display connected to a Thunderbolt 3 port on your Mac, the display will be blank (black, gray, or blue) for up to 2 minutes during installation.

How to switch between Windows and macOS

Restart, then press and hold the Option (or Alt) ⌥ key during startup to switch between Windows and macOS.

Manage windows on Mac

When you open an app or the Finder on your Mac, a window opens on the desktop. Only one app at a time is active; the name of the app (in bold) and the app menus are shown in the menu bar.

Some apps, such as Safari or Mail, let you open multiple windows or different types of windows at the same time. macOS provides several ways to manage open apps and windows.

Move, align and merge windows

On your Mac, do any of the following:

Move a window: Drag the window by its title bar to where you want it. Some windows can’t be moved.

Align windows: Drag a window close to another one — as the window nears the other one, it aligns without overlapping. You can position multiple windows adjacent to each other.

To make adjacent windows the same size, drag the edge you want to resize — as it nears the edge of the adjacent window, it aligns with the edge and stops.

Merge an app’s windows into one tabbed window: In the app, choose Window > Merge All Windows.

To make a tab a separate window again, select the tab, then choose Window > Move Tab to New Window, or just drag the tab out of the window. See Use tabs in windows.

Maximise or minimise windows

On your Mac, do any of the following in a window:

Maximise a window: Press and hold the Option key while you click the green maximise button in the top-left corner of an app window. To return to the previous window size, Option-click the button again.

You can also double-click an app’s title bar to maximise the window (as long as the option to do so is set to “zoom” in Dock & Menu Bar preferences).

Minimise a window: Click the yellow minimise button in the top-left corner of the window or press Command-M.

You can set an option in Dock & Menu Bar preferences to have a window minimise when you double-click its title bar.

Most windows can be manually resized. Drag the window’s edge (top, bottom, or sides) or double-click an edge to expand that side of the window.

Quickly switch between app windows

On your Mac, do any of the following:

Switch to the previous app: Press Command-Tab.

Scroll through all open apps: Press and hold the Command key, press the Tab key, then press the Left or Right arrow key until you get to the app you want. Release the Command key.

If you change your mind while scrolling through the apps and don’t want to switch apps, press Esc (Escape) or the Full Stop key, then release the Command key.

Close windows

On your Mac, do any of the following:

Close a single window: In a window, click the red Close button in the top-left corner of the window, or press Command-W.

Close all open windows for an app: Press Option-Command-W.

Closing one or all windows for an app does not close or quit the app. To do so, press Command-Q, or click the app’s name in the menu bar, then choose Quit [App]. See Quit apps.

You can hide the active app by pressing Command-H.

Use Mission Control to quickly arrange open windows and spaces in a single layer to easily spot the one you need.

Easily Run Windows Applications on Mac OS X

If you are using Mac OS X and want to run Windows applications, the most popular option is to install Windows OS using Bootcamp, or run Windows in a virtual machine. Linux users will know that you can use Wine to install and run Windows applications natively. The good news is that Mac users can run Wine to install Windows applications as well. Wineskin is a Wine-tool ported over to the Mac platform. Check out how you can run Windows applications on Mac OS X.

Wineskin is simply an implementation of Wine at its core. For those who are not sure what Wine (an acronym for “Wine Is Not an Emulator”) is, it is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, including Linux and Mac OS X.

Installation

The installation is pretty straight-forward.

1. Download Wineskin. The latest version as of this post is 2.5.12.

2. Extract the file and move the Wineskin app to your Applications folder. Open it.

On the first run, there won’t be any engine showing up in the list. Click the “+” button to download and install the latest engine. The engine is required to make the Windows applications work.

Once the engine is installed, you are ready to install Windows applications.

Installing Windows applications

Before you start, make sure you have the executable file of the desired Windows application with you. Note that Wineskin doesn’t support all the Windows applications out there. Check out Wine’s AppDB to see if the application you want is supported.

1. Click the “Create New Blank Wrapper” button and enter a name for this wrapper. In this example, we will be installing Peazip on Mac.

While creating the wrapper, it will prompt you to install mono package for running .Net applications and Gecko package for running HTML-based apps.

2. Once the wrapper is created, open it in Finder; right click and select “Show Package Content.”

You should see two folders: “Contents” and “drive_c” and a Wineskin app. Run the Wineskin app.

3. Select “Choose Setup executable” and select the executable file of the Windows application.

The installation will proceed just like it does in Windows.

Running Windows applications

Run the Wineskin app (from the Wrapper folder) again. This time, click “Advanced.” Browse and select the installed application and click “Test Run.” This will run the Windows application.

This is what the application will look like:

Once you are happy with the test run, the next time you can just double click the Wrapper app to open this application.

Conclusion

If you need a Windows environment in Mac, your best bet would be either using Bootcamp or to run a virtual machine. However, if all you need is a particular Windows application, using Wineskin is a better option (provided that the application is supported). If you have a lot Windows game in your collection, you will be happy to know that plenty of those older games are supported by Wine, and you can now play them on your Mac machine. Enjoy!
