What is the best virtual machine application for MAC? How to run windows on MAC? How to run old macOS into unsupported device? all of these question can be replied by selecting the best software for virtualization, Emulation and best virtual machine software for MAC.

1- What are the virtual machines ?
          Virtualization software like Parallels Desktop and VMware Fusion can be used with macOS, enabling users to create Virtual Machines (VMs) that mimic the hardware environment of a Windows-based PC or another MAC hardware. So, users can generate a VM on their macOS and install Windows, or alternatively, another operating system such as Linux or macOS into the VM. This approach offers a way to run windows applications on MAC side by side to MAC applications.
             However, one drawback is that a high-performance Mac with plenty of memory and  a large storage is necessary to effectively run Windows within a VM on MAC, as it essentially involves the concurrent operations of two distinct operating systems on the same machine.

2- What are the classification of virtualization for Mac? 
1- Free and/or paid.    2- Separate windows from macOS.
3- Emulators.               4- Virtual Machine Software.
   
A- What are the free virtual machine softwares for MAC?
1- Boot Camp. (Bootcamp-assistant user guide⇗) 
2- VirtualBox. (Oracle VirtualBox Download⇗)
3- UTM virtual machine for Mac. (UTM Virtual Machine download⇗)
4- Wine. (Winehq download⇗)

B- What are the paid virtual machine softwares for MAC?
1- Parallels desktop.  (Parallel Desktop free trial⇗) 
2- CrossOver For MAC. (CrossOver free trial⇗)
3- VMWARE Fusion for MAC. (VMware fusion download ⇗) 
​4- Windows 365. (windows 365 Download⇗) 

C- What is Boot Camp? ​

Boot Camp is a free utility software included with macOS versions that allows users to install and run Microsoft Windows operating system on Intel-based Mac computers. It enables users to partition their Mac's hard drive, creating a separate section where Windows can be installed. Once Windows is installed via Boot Camp, users can choose to boot their Mac either into macOS or Windows, effectively turning their Mac into a dual-boot system.  
          Millions of Intel-based Macs are still in active use globally, capable of employing either Boot Camp or virtualization to run Windows. However, beginning in 2020, Apple initiated a transition away from Intel processors towards its proprietary Apple Silicon Processors. Unlike Intel processors which utilize the x86 architecture, Apple's silicon processors (M Series) operate on a distinct architecture known as ARM.
              These Mac models do not support Boot Camp. Even if Boot Camp were available for current intel Macs, due to the incompatibility between M-series processors and the x86 version of Windows, they would only be capable of running an ARM Version of Windows. the good news that the ARM-compatible version of Windows is available for download in Microsoft website. Once, you provide the Windows ISO images, the Boot Camp Assistant does all the work 

​              Emulation is a procedure aimed at running specific Windows applications on your Mac without requiring the installation of the Windows operating system itself. Tools like Wine and CrossOver are examples of emulation software. this requires a more experienced users as there are many manual configurations. They are often reasonably priced or even available for free. Most windows applications can be used in macOS through emulation.
