+
+This post is a Mac version of a post I wrote a couple of years ago titled [Take Your Windows Terminal and Powershell to the next level](/next-level-powershell-prompt).  
+
+![Michael's PowerShell Terminal](/images/powershell/powershell-prompt-example.png)
+
+Let’s walk through the steps I took to get my shell working like Michael's on Mac.
+
+<!--more-->
+
+Several items need to be installed for the profile to work:
+
+* Nerd Font - this is the font that provides the icons for folders and files
+* Starship - The minimal, blazing-fast, and infinitely customizable prompt for any shell!
+* Terminal-Icons - PowerShell module to display the icons from the Nerd Font
+* devtoolbox - a PowerShell module with a bunch of useful aliases for dev tools that Michael released
+* PSReadLine - a PowerShell module that allows predictive suggestions as you type a command
+
+## Font Install
+
+Nerd Fonts patches developer targeted fonts with a high number of glyphs (icons). Specifically to add an increased number of extra glyphs from popular ‘iconic fonts’ such as Font Awesome, Devicons, Octicons, and others.
+
+I am using the CaskaydiaCove Nerd Font from [Nerd Font](https://www.nerdfonts.com/font-downloads).
+
+To install:
+
+1. Open Terminal or whatever shell you are using
+1. Update brew with the nerd fonts
+
+    ```shell
+    brew tap homebrew/cask-fonts
+    ```
+
+    > If you are not using brew, you can install it at [https://brew.sh](https://brew.sh)
+
+1. Install the font
+
+    ```shell
+    brew install --cask font-caskaydia-cove-nerd-font
+    ```
+
+## Powershell Install
+
+1. After the font is installed, you need to install Powershell
+
+    ```shell
+    brew install powershell/tap/powershell
+    ```
+
+1. To Launch Powershell, run:
+
+    ```shell
+    pwsh
+    ```
+
+## Powershell Profile Setup
+
+Next, we need to tell Mac Terminal to use the CaskaydiaCove Nerd Font that was just installed.
+
+1. In Terminal, Open settings by pressing Command+, or clicking on the Terminal menu and selecting Settings
+1. Click the + to add a new Profile or Duplicate your existing profile
+1. Name the new profile Powershell
+1. Click the Change... button under Font
+1. Click All Fonts
+1. Find CaskaydiaCove Nerd Font and Select it
+1. For the style, select Regular
+1. Click the Font Window
+
+Now we need to tell Terminal to automatically launch Powershell as our default Terminal shell
+
+1. Under the settings for the Powershell profile, click the Shell tab
+1. Under Startup, check the Run command: box
+1. Add the following command:
+
+    ```text
+    /usr/local/microsoft/powershell/7/pwsh
+    ```
+
+1. Uncheck Run inside shell
+1. Under the Ask Before closing, add the following:
+
+    ```text
+    -pwsh
+    pwsh
+    ```
+
+1. Close the Settings
+1. Quit Terminal and Relaunch it
+
+## Use brew in Powershell
+
+In order to use brew in Powershell you need to run the brew shellenv command to set up the profile environment variables.
+
+1. Run: `vi $profile`
+1. Add the following to the file:
+
+    ```text
+    $(/opt/homebrew/bin/brew shellenv) | Invoke-Expression
+   ```
+
+1. Refresh the Powershell profile by running
+
+    ```powershell
+   . $profile
+   ```
+
+   > You might need to restart Terminal for the profile changes to be picked up
+
+## Starship
+
+Next, we need to install [Starship](https://starship.rs/), the minimal, blazing-fast, and infinitely customizable prompt for any shell!
+
+You install Starship using
+
+```shell
+curl -sS https://starship.rs/install.sh | sh
+```
+
+> Note: I had issues installing starship with brew and Powershell not recognizing starship command, so using manual install above.
+
+Now that we have Starship installed, we need to add it to our PowerShell profile.
+
+1. Open PowerShell
+1. Open the profile by typing `vi $profile`
+1. Add the following line at the top of the profile and save it
+
+    ```PowerShell
+    Invoke-Expression (&starship init powershell)
+    ```
+
+## Terminal-Icons
+
+[Terminal Icons](https://github.com/devblackops/Terminal-Icons) is a PowerShell module to show file and folder icons in the terminal.
+
+1. To install, open PowerShell and run:
+
+    ```PowerShell
+    Install-Module Terminal-Icons -Scope CurrentUser
+    ```
+
+1. To use the Terminal Icons, add the following line to your PowerShell profile
+
+    ```PowerShell
+    Import-Module Terminal-Icons
+    ```
+
+## devtoolbox
+
+[devtoolbox](https://github.com/builders-club/devtoolbox) is a set of aliases for common developer command for docker, docker-compose, and git.
+
+You can install devtoolbox from the [PowerShell Gallery](https://www.powershellgallery.com/packages/devtoolbox/)
+
+```PowerShell
+Install-Module -Name devtoolbox
+```
+
+To use the devtoolbox now that we have installed it, open up your PowerShell profile and add the following statement.
+
+```PowerShell
+Import-Module devtoolbox
+```
+
+## PSReadLine Predictions
+
+For the predictive suggests when typing commands, we need to install PSReadline.
+
+In a PowerShell administrator shell, run
+
+```PowerShell
+Install-Module PSReadLine -RequiredVersion 2.2.2 -Force
+```
+
+> Needed to use -Force to have it install PSReadLine 2.2
+
+To our PowerShell profile, we need to add the following lines:
+
+```PowerShell
+Import-Module PSReadLine
+
+Set-PSReadLineOption -PredictionSource History
+Set-PSReadLineOption -PredictionViewStyle ListView
+Set-PSReadLineOption -EditMode Windows
+```
+
+## update function
+
+The update function is designed to make it easy to update powershell to the latest version
+
+```PowerShell
+function update {
+  brew update
+  brew upgrade powershell
+}
+```
+
+I would suggest that you run the `update` command and install the latest cross platform version.  Once you get the cross-platform version installed, you need to install the PowerShell modules above and create the profile.
+
+## profile ended
+
+The last piece is to set up the profile function to launch the profile into VSCode quickly.
+
+```PowerShell
+function profile {
+  code $profile
+}
+```
+
+Now your prompt is just like Michael's.
+
+## Full PowerShell Profile
+
+There is a couple of bonus functions like getting a random fact, a dad joke, convert a temp to C, and convert a temp to F.
