This is where the other option, known as 'virtualisation', can come in handy.
Instead of splitting your hard drive into separate partitions for macOS and Windows, you use a virtualisation program such as Parallels Desktop or VMware Fusion ; for more options see best virtual machine software for Mac to create a 'virtual machine' that runs within macOS itself. The virtual machine VM is simply an app that runs on the Mac just like any other Mac app. However, the virtual machine mimics the workings of a PC, allowing you to install Windows on the virtual machine, and then install any Windows apps that you need to run as well. This is definitely the most convenient option, as it means that you can run your Windows apps on the Mac desktop right alongside all your normal Mac apps, so there's no need to dual-boot back and forth between the macOS and Windows as you do when running Boot Camp.
But virtualisation has disadvantages too.
Running Windows within a virtual machine means that you're effectively running two operating systems at the same time, so you're going to need plenty of processor power and memory to get decent performance when running your Windows apps. Even so, most recent Macs can still provide good performance when running Windows in a virtual machine, and it's only 3D games and high-end graphics apps that need the extra power you can get from dual-booting with Boot Camp.
If you want to run Windows 10 on your Mac you can download it as a 'disk image' file - sometimes also called an 'ISO file' - from Microsoft's website. However, these versions of Windows were originally sold on disk, so if you still have the original disk then it's probably quicker to create the ISO file using the installer program on the disk. This is actually quite straightforward, and Apple covers this option on its website too.
Install Windows Mac Without Boot Camp software . a bootcamp partition on an old mac pro (without problem). just bought an external dvd. In macOS High Sierra and earlier, you can install Windows 10, Windows , and Windows 7 using Boot Camp Assistant on supported Mac.
Now you have Windows install files you just need to get Boot Camp or your Virtualisation software up and running so you can install it. You'll find the Assistant located in the Utilities folder within the main Applications folder on your Mac - but before you run the Assistant there are a few things that you will need to run Windows in Boot Camp. Once you've completed those preparations you'll be ready to run Boot Camp Assistant and install Windows on your Mac.
Here's what to do:. When you run Boot Camp Assistant for the first time, it will prompt you with a number of options. The first option is to confirm that you want to 'Create a Windows 7 or later install disk'. However, it will only download the drivers for Windows 8. If this is your first time using Boot Camp then, of course, you'll also need to select the option to 'Install Windows 7 or later'.
This will allow you to split - or 'partition' - your Mac's hard drive into two separate sections, known as 'partitions'. The normal macOS is left on one partition, while the second partition is used to install Windows and any other Windows software and apps that you want to use. By default, Boot Camp Assistant offers to create a small Windows partition that is only 32GB in size, but you can use the slider control to adjust the size of the two partitions as required. There's also a button that will simply split the drive into two partitions of equal size. If your Mac has more than one internal hard drive or SSD, it's possible to devote one of those drives exclusively to Windows.
However, Boot Camp doesn't play well with external drives connected via USB or Thunderbolt, so it's best to use your normal internal drive wherever possible. And if you have an external drive connected to your Mac for Time Machine backups then it's a good idea to remove it as Boot Camp can get a bit confused if it detects an external drive during installation. You can just follow the prompts to install Windows.
As soon as Windows starts up you will also be prompted to install the additional Boot Camp drivers from the memory stick as well. Once that's done you can simply 'dual-boot' between the macOS and Windows by pressing Alt aka Option on your keyboard when you turn the Mac on. You'll see the two partitions with the macOS and Windows displayed on screen as the Mac starts up, and you can simply select whichever operating system you need. Virtualisation programmes such as Parallels Desktop and VMware Fusion provide an ingenious and flexible alternative to the dual-boot approach of Boot Camp.
Instead of splitting your Mac's hard drive into separate partitions, and then installing Windows on to the Boot Camp partition, these programs create a 'virtual machine' - or VM - which is simply an app that runs on the Mac and acts like a PC. You can then install Windows on the VM, along with whatever Windows apps and software that you need to run. The VM can run alongside other Mac apps, such as Safari or Apple Mail, so there's no need to switch back and forth between the two operating systems, as you are forced to do with Boot Camp.
These programs aren't free, so you'll need to buy a copy of the program you prefer, as well as providing your own copy of Windows although both Parallels and VMware do provide trial versions that you can look at to see which one you prefer. There is also a free virtualisation program, called VirtualBox , but it's fairly complex and difficult to use, so we'll focus first on using Parallels and VMware to install Windows. Jump down to the VirtualBox section if you feel ready for the challenge.
We have more information about the Best virtual machine software for Mac here. Parallels Desktop on version 14 at time of writing has a more colourful graphical interface than VMware Fusion, but the two programs take the same basic approach. And, if you're already using Boot Camp, you can even create a VM that duplicates your Boot Camp partition - which is a handy option for quickly checking a few files, or running apps that don't need top performance, without having to shut the Mac down and boot into Windows.
Once you've decided how you want to install Windows, both programs allow you to adjust a number of important settings. VMware is a little more complicated, as it displays a window with a lot of settings that might seem a bit daunting to first time users. Parallels makes things a bit easier for beginners, by providing a number of predefined options that are suitable for productivity software such as Microsoft Office, or running heavy-duty 3D games, or design software. Both VMware Fusion and Parallels allow you to change the 'hardware' configuration of your VMs if you need to, just as though you were choosing the physical hardware for a real Mac or PC.
If your Mac has a multi-core processor such as the iMac Pro , which has up to 18 processor cores then you can devote multiple cores to your VM in order to improve performance.
You can also allocate extra memory and disk space, and even increase the amount of video memory that your VM can use for handling 3D graphics in games and other graphics software. Other options provided by both Parallels and VMware include the ability to connect external devices, such as a hard drive or even Bluetooth speakers to your Windows VM.
You can also determine how your VM interacts with the macOS on your Mac, perhaps sharing specific folders and files that you need for a work project, or sharing your music or photo libraries. A key aspect of how your VM runs on your Mac is the way it appears when it's running on the Mac desktop. By default, both Parallels and VMware run their VMs in a window - so you get a kind of 'Windows window' that displays the Windows desktop floating in its own window on top of the Mac desktop. A pop-up will appear asking you if you want to format it to continue, select the partition scheme you want to use and click "Yes" to format it.
If you choose "Keep the existing partition scheme", you need to manually prepare the partitions on the USB drive before this step, and here is the user guide on how to manually prepare partitions for Windows To Go.
Please note that the "Keep the existing partition scheme" option is valid only for an external disk. Step 6. Select the system partition and boot partition from the partition list, the selected partitions will be marked as red, then click "Next". Step 7. Step 8. It takes some time to install. Step 9. Step Windows normal installation starts up and you have to complete all the installation steps, If the Mac's own keyboard or touchpad does not work, you have to use an external USB keyboard or mouse to complete the installation. After that, you can install boot camp, programs, copy files, etc.
