VirtualBox is an open source alternative to Parallels for Mac and VMware Fusion. It was first released in 2007 and acquired by Oracle in 2010. It can be used to load multiple guest operating system under a single host operating system, and it supports both Intel’s VT-x and AMD’s AMD-V hardware virtualization.
- Pros
Fast performance in testing. Tight integration with guest OSes. Effortless installation. Flexible file and folder tools. Options for opening Mac files in Windows apps. Can install macOS virtual machines directly from the Mac recovery partition.
- Cons
Some Mac-integration features can be confusing or impractical until you turn them off. Only runs on a Mac, so you can't share guest machines with Windows or Linux users.
- Bottom Line
Parallels Desktop is an excellent way to run Windows apps on MacOS, especially for ordinary users. It's fast in testing, offers tight integration between Macs and guest systems, and supports many other OSes, too.
Parallels Desktop is the fastest and friendliest way to run Windows apps on a Mac for the majority of users who are likely to want to do so. IT pros may prefer VMware Fusion; expert users who want no-cost apps will prefer the open-source VirtualBox. Hardcore gamers may prefer Apple's Boot Camp, which lets users boot directly into Windows, with the added bonus of native graphics card support. For most ordinary Mac users who prefer Windows versions of apps like Microsoft Office or AutoCAD, however, or who use Windows-only apps like CorelDraw or WordPerfect Office, Parallels Desktop is the clear first choice for virtualization software.

Platforms and Pricing
Parallels Desktop supports all Windows versions since Windows 2000, all Intel-based macOS versions (with some exceptions for licensing reasons), many flavors of Linux, BSD, Solaris, and a few other OSes. VMware Fusion and VirtualBox are even more flexible, and can run historical curiosities like OS/2 and NeXTSTEP. Also, unlike Parallels Desktop, VMware Fusion and VirtualBox have versions that run on Windows and Linux machines, while Parallels Desktop is Mac-only.
There's one other important difference: Parallels Desktop is a subscription-only product, so you'll have to pay $79.99 per year for the home-and-student version or $99.99 for the Pro Edition. VMware Fusion has a one-time cost (a model some consumers may prefer) of $79.99 for its standard version and $159.99 for its Pro version. VirtualBox is free for personal use and $50 for corporate use, but you get far fewer convenience features out of the box with this open-source product.
Get Started With Parallels
Parallels starts up with a menu for creating a new virtual machine or opening an existing one. This is where Parallels' focus on ordinary end users shines best. Unlike all other virtualization apps, Parallels doesn't expect you to have a Windows or Linux installer disk or disk image ready when you start it up, although it can use that image if you have one. Instead, Parallel's user-helpful menu lets you buy a Windows 10 download directly from Microsoft, or simply download a Windows 10 installer if you already have a license key.
Another set of options lets you install a Parallels system-export utility on your Windows PC, and export it to Parallels via a network (slowly) or an external drive. A scrolling list at the foot of the menu lets you download specific versions of Linux or Android, install a virtual copy of macOS from your Mac's hidden recovery partition, or install Windows from a Boot Camp partition if you have one.
Like VMware and VirtualBox, Parallels supports a Snapshot feature that lets you save a guest system in one or more configurations that you know works well, and then restore a saved configuration after making changes in the system that you don't want to preserve. However, Parallels is unique in supplementing this feature with a Rollback option that automatically discards all changes to a system when you shut it down, so it works like a kiosk system, returning to its pristine condition every time you power it up. This feature can be invaluable in testing, or in environments like schools where users are liable to leave systems a lot messier than they found them. If you used Microsoft's long-abandoned VirtualPC app, you'll remember this feature, and will welcome its return in Parallels.
Parallel's Performance
Compared to VMware, Parallels starts up Windows at top speed in testing. On my vintage 2015 MacBook Pro, Parallels boots Windows 10 to the desktop in 35 seconds, compared to 60 seconds for VMware. VirtualBox matches Parallels' boot speed, but it performs far fewer integration tasks while booting up. For example, VirtualBox doesn't provide printer integration and the ability to open Windows files with Mac apps and vice versa.
One reason for Parallels' bootup speed advantage is that Parallels uses an emulated PC BIOS that supports the Fast Startup option, and the others don't. The speed difference isn't nearly as obvious when running Windows apps after the OS starts up, however. Parallels feels slightly faster than its rivals, but not drastically so. Fast as it is, Parallels won't satisfy hard-core gamers because Parallels, like VMware Fusion, only supports DirectX 10, while VirtualBox only supports DirectX 9. There's nothing that Parallels can do about this limitation, which is the result of the Mac's limited support for OpenGL (Open Graphics Library) features.
By default when Parallels runs a Windows system, any files on your Mac desktop will also appear on your Windows desktop. This may sound convenient, but it's a feature that I always to turn off in Parallels' settings dialog. One reason I turn it off is that it leaves the Windows desktop cluttered. Another is that much of what I keep on my Mac desktop—like folders and apps—simply won't work when I click on them in Parallels' Windows desktop. Parallels tends to go overboard with integration features, turning them on by default whether you want them or not.
Another way Parallels goes overboard with its integration is its tendency to clutter up its dialogs and your Mac system with icons and folders that you probably don't want. For example, by default, it adds a folder full of Windows application to your Mac's dock, and a Parallels menu to Mac's menu bar—though you can turn these off by poking around the options and preferences windows. Some of Parallels' menus include links to a set of Mac-related utilities called the Parallels Toolbox; some of these utilities, like a quick disk-cleaning menu, are convenient, but you probably don't want all of them, and they have nothing to do with virtualization. Another link on Parallels' menus invites you to buy Acronis True Image backup software, which you probably don't need if you use your Mac's built-in backup features.
Parallel Computing
Anyone who wants to run a Windows app on the Mac should choose between our two Editors' Choice apps, Parallels Desktop and VMware Fusion. For IT managers, developers, and for many tech-savvy users, VMware is the best choice. For most home, school, and SOHO users who don't need VMware's unique cross-platform support and legacy features, Parallels Desktop is the fastest, most hassle-free way to run Windows apps on a Mac.
Parallels Desktop (for Mac)
Bottom Line: Parallels Desktop is an excellent way to run Windows apps on MacOS, especially for ordinary users. It's fast in testing, offers tight integration between Macs and guest systems, and supports many other OSes, too.

Move over emulation, virtualization is in and it's hotter than two Jessica Albas wresting the devil himself in a pit of molten steel. It's no contest, virtualization has it all: multiple operating systems running on the same machine at nearly the full speed of the host's processor with each system seamlessly networking with the next. Add to that the fact that it's cheaper than getting a new machine and you have the guaranteed latest craze. Not even the Hula Hoop can stop this one.
Okay, virtualization isn't totally new–it's just new to Macs and Parallels Desktop is the first out the door with a 1.0 product for Mactels. For those that are just getting to the party, here's a bit of a breakdown on virtualization. The idea is that program acts as a virtual machine (VM) and its job is to bethe PC (one of the more boring drama classes), tricking the client OS into thinking it's inside a real x86 machine with a physical hard drive, keyboard, Ethernet card, etc., when in reality, it's merely grabbing unused CPU cycles and RAM inside another OS to do it's thing.
The benefits are pretty clear over a real PC: It's running on the Mac you know and love but you're not sacrificing access to the occasional Windows-only app that you might need. Maybe you have a copy of Office XP for Windows and don't want to shell out for the Mac version. Sure, you could load up Apple's Boot Camp, but using a program like Parallels–or its competitors VMWare, WINE and MS' Virtual PC–means you don't have to reboot just to use that accounting program at work.
It is a great prospect and now even Apple is recommending running Parallels on their Get A Mac site:
Parallels Free For Mac
That's the corporate equivalent of Jesus endorsing your sandals. Click for high res.
When that page went up, the price of Parallels not-so-coincidentally went up from $50 to $80, so let this be a lesson to us all: never say 'wow, that's so cheap' on a public forum again. Still, that's still cheaper than the $129 charges for the Virtual PC standalone package and if it works as advertised, it's hard to compare the two. Parallels promises to be a big upgrade from the pokey and painful Virtual PC emulation. So let's see if it's the cheap and fast hydra PC we've all been waiting for.
