It can be said that it is a copy of the original one. Virtualization is the process where a user can create a virtual or actual image of something. In this article we are discussing the downloading process and why it is important as well as useful to the user. The user can easily download macOS 10.15 Catalina Virtual Image by using the procedure of downloading. Some examples of these machines are VMware, VirtualBox, or Hyper-V. If the user operates Mac from their desktop then they have to use it through a virtual machine. The latest application this software has introduced is the voice control panel, apple watch, and Siri shortcuts. Moreover, it also has sidebars’ availability and iPad external display. It also controls the voice over the device of Mac. Other available features Catalina includes are music, application of books, and some attachments of security.

It includes a new feature of web recording where a user can easily record the browser and keep it as a data. It has the ability to transform an iPad into its display. Catalina has introduced advanced new features that are available in MacOS 10.15. It is considered as one of the best and most recommended innovations Apple ever had. That should last a few weeks 🙂 Set-VMHost -MacAddressMinimum 00155D010000 -MacAddressMaximum 00155D01FFFF Setting the MAC address pool via PowerShell.Apple has an updated Operating System (OS) called Catalina, especially designer under Mac. In this example I'm increasing it to 65536 machines. The solution? Simply increase the MAC address pool, either in the GUI or in PowerShell. $AllNICs = Get-VM | Get-VMNetworkAdapter | Where-Object Running the script on my Hyper-V host, showing I have a few machines with duplicate MAC addresses. Cred goes to Didier Van Hoye for the loop logic. If you think you are having machines with duplicate MAC address, simply run this script on your Hyper-V host to find out. The PowerShell command (for copy and paste) is: Get-VMHost | Select MacAddressMinimum, MacAddressMaximum | ft Checking for duplicates Getting the MAC address pool via PowerShell. You can see/edit the MAC address pool in the virtual switch manager, or via PowerShell. Especially if that other VM is still around. That means, once you deploy virtual machine number 257, it's going to reuse an existing MAC Address. When installing Hyper-V, it' sets up a MAC Address Pool of only 256 machines. This time I figured that if I blog about it, I'm more likely to remember it next time 🙂 Background I forgot to increase the MAC Address pool on a new lab server, and started to get VMs with the same MAC address in my environment.
