How to Set up VirtualBox
Install Virtual Box
Open your web browser and visit virtualbox.org to download the software. After installing the app, return to its site, click “All supported platforms” next to “VirtualBox Extension Pack” and install that, too.
Configure storage
Leave the default “Hard disk file type” selected and click Continue. Do the same for “Storage on physical hard disk” by clicking Continue again. Choose the size and location for your virtual disk, then click Create.
Set up Windows
When the virtual machine opens, dismiss alerts about mouse and keyboard integration. At “Where do you want to install Windows,” pick your virtual disk and click Next. Continue setup as you would on a regular PC.
Get Windows
To proceed, you need a DVD or ISO image of Windows 10. ISO images are available at bit.ly/mf320virtualbox. You must enter a valid product key within 90 days of installing Windows 10 in order to keep using it.
Add media
Choose Machine > Settings, then click Storage. Select the CD in the Storage Devices tree, then click the CD icon, and then either your DVD drive or Virtual Optical Disk File and your Windows 10 ISO file.
Guest additions
Once Windows’ desktop appears, choose Devices > Insert Guest Additions CD image. Go to that CD in File Explorer and run VBoxWindows Additions.exe to install extra features. Select Reboot Now and click Finish.
Set virtual machine
Click New at the top left of the app. Next to Name, enter “Windows 10,” and click Continue. Adjust the slider on the Memory Size page to allocate at least 2048MB of memory to your virtual machine.
Add USB support
Click Ports and then the USB tab. Click the blue icon at the top right of the device filters box to add one or two empty filters; this enables you to connect USB devices to Windows. Click OK to save settings, and then Start.
Attach USB devices
Connect a USB device to your Mac, but ensure you eject it in Finder before proceeding. While your virtual machine is running, go to Devices > USB and select your device there to make it available to Windows.
