 # Frequently Asked Questions
 
-Currently, there are no frequently asked questions.
+Does the Azure to Azure migration toolkit work on Mac?
+    Yes it does.
+
+    - Follow the below steps as pre-requisites so that you can successfully use A2ATK on a Mac.
+
+1. Install homebrew if you do not have it. Open a terminal and run
+
+/bin/bash -c "$(curl -fsSL [https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh](https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh))"
+
+More info can be found here: [https://brew.sh/](https://brew.sh/)
+
+1. Once homebrew is installed, Install PowerShell.
+
+brew install powershell
+
+3. The executable to get into PowerShell is "pwsh". In a terminal you can type "pwsh" and you will get a PowerShell prompt.
+
+└🤘-> pwsh
+PowerShell 7.5.2
+PS /Users/user>
+
+4. Now install the required modules.
+
+    Install-Module Az (This is the Azure PowerShell Module)
+    Import-Module Az (Import the module)
+    Install-Module -Name Az.CostManagement (This is the Azure Cost Management PowerShell Module)
+    Import-Module Az.CostManagement (Import the module)
+    Install-Module -Name ImportExcel (This is the Excel PowerShell Module) - So that it can export to Excel correctly.
+
+    One last package that needs to be installed to get the Excel formatting done correctly is mono-libgdiplus
+    You can do this by running
+
+    brew install mono-libgdiplus
+
+Now just follow the rest of the steps in the Docs as if you were running Windows. All the commands will work in pwsh from the Mac terminal.
