Parallels Desktop for Mac
Score 9.7 out of 10
N/A
Parallels® Desktop for Mac is used to run Windows on Intel or Apple silicon. Users can switch between Mac and Windows applications, while retaining the macOS appearance, or use the familiar Windows desktop aesthetic.
It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.
Parallels works just like a window or application on the Mac. Hence, it is beneficial to keep both OS versions hand in hand. Parallels is very useful when writing code for mobile/iOS applications. File sharing and paste functions are very easy to use. More than one machine can be taken on Parallels. It also integrates with Microsoft Intune. It can run other OS versions other than Windows.
Can spin up multiple VMs on a host-only network that speak to each other and allow for interesting test environments spun up at will.
Cross-platform functionality allows me to run it on my Linux Desktop and know that tutorials I make with it could be approached by someone on a Windows or Mac OSX system. Hyper-V is limited to Windows, and VMware Workstation requires a license (VMware Player is free, but is not open-source and is more limited in comparison to VirtualBox).
If you are testing tools like Vagrant and Test-Kitchen, VirtualBox often seems to have the highest amount of support and documentation when it comes to compatibility (though, many people do use Hyper-V or VMware Workstation without issues).
File Transfer - You can easily transfer files between Parallels virtualized desktops and the host desktop either through Copy and Paste functionality, or Drag and Drop. You can also configure shared folders.
Switch Between Virtual and Host Desktop - You can configure swipe gestures on a MacBook Pro to be able to switch between the virtualized and host desktop. You can also launch apps from the OS X Taskbar.
Performance - Apps in Parallels run quite smoothly on my 2015 MacBook Pro, as of 2020. Considering they are running on a 5-year-old computer, I give Parallels top marks for performance.
The memory footprint is high, and requires above 8 GB of memory to run an Ubuntu VM smoothly (considering developing inside ubuntu OS inside a MacBook Pro).
Some known issues with OVF/OVA images import/export. We had the issue of some sections in OVF being ignored (especially Startup and Install sections).
Some intermittent issues when mounting external hard drives and trying to access them from within the running VM.
The ability to do snapshots, backups, and other types of branching for VMs is a little confusing and takes a bit to get used to
The Parallels tools frequently pop up windows advertising functionality, while this is helpful at times it can also happen when you are doing a presentation or typing in a password.
Careful using the VMs on a shared cloud drive such as Dropbox or OneDrive, there are hundreds and sometimes thousands of files which are updated when running a VM and this can clog up your Dropbox or OneDrive sync for minutes to hours even on a 2gb connection.
We are completely pleased with the ease of deployment and use with Parallels. It has proven to be reliable, and Parallels technical support is there when we need them. There is a large user audience online for peer consultations and discussions. In general, it is a functional and easily maintained utility which serves our needs.
I love using the Graphical User Interface. The VirtualBox Manager is very easy to understand and use. You can quickly create, configure and manage all your virtual machines in one window. It makes operating virtual machines easy and simple. When using VBoxManage it gives the user comprehensive control over VirtualBox so that you can use automation and scripting at the command-line interface
It has a good integration, including the connection of peripherals. Taking files back and forth works well and I can attach my Home drive as a network drive in Windows. There is even integration with iCloud and other macOS services. There are also a few different display modes which are useful and fleixible (coherence, windowed, full-screen with multiple screens)
So, this rating is a little skewed toward older behavior from Parallels, as I haven't had to contact them recently. However, in an older version of Parallels, an "update" included pop-ups urging users to upgrade to the latest version, implying that their current version wouldn't work for the latest MacOS. I found it very frustrating to be getting ads for a new version of the software in a version I had already paid for. I contacted support about this and got a generic, uncaring response. It was pretty disappointing.
VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition
Parallels provides what we need at a reasonable cost. VMware was a bit pricier, and Parallels has more of a "Mac-like" feel for the application itself. UTM and Crossover were a bit too "hacker-ish" for basic end users that just want to pop in and out of windows when necessary. Parallels is well supported and easy to use. It is also heavily used in Higher Education, which gives us a peer audience to work with.
The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.
The cost versus benefit is definitely in the users' favor - the licensing terms for simple desktop usage are very generous, and the business impact is enormous, being able to seamlessly jump from one OS to the other without dealing with multiple physical VMs or cloud remote sessions.
