+## Mac Focussed? 🍏
+
+While the _installation_ steps below
+include Mac-specific steps like `Homebrew` and `XCode`,
+this guide can still _easily_ be followed by people
+using Linux or Windows as their OS.
+
+The _reason_ we use **`Mac`** is simple: 
+it's the _only_ way to ship apps for **`iOS`**.
+
+Like it or not, **`iPhone`** now has a 
+**`50%` Market Share in the US**:

+
+In Europe, **`iPhone`** ownership/use correlates strongly to wealth of the nation;
+Monaco and Norway the two countries with the highest GDP/Capita top the table 
+with 
+[**`69.91%`**](https://www.reddit.com/r/MapPorn/comments/xx4gp6/percentage_of_iphone_users_in_europe/) 
+and 
+[**`68.89%`**](https://gs.statcounter.com/os-market-share/mobile/norway) 
+respectively.

+
+Worldwide **`iPhone`** a **`~30%` Market Share**:
+https://gs.statcounter.com/os-market-share/mobile/worldwide
+Mostly because there are _many_ cheap Android devices 
+that have flooded the market.
+
+But by _far_ the most important fact/stat to pay attention 
+from an Native Mobile App development perspective is:
+
+### "_`iOS` users spend more than double on subscriptions compared to `Android` users_"
+
+https://www.phonearena.com/news/app-store-users-spend-more-than-double-google-play-users-subscriptions_id138692
+
+So ... if you're building a **`SaaS` product**,
+you should pour _most_ of your effort into perfecting the UI/UX on **`iPhone`**.
+
+This is why we use **`Mac`**computers for our **`Flutter`** dev.
+So we can run **`XCode`** and test on **`iOS`** devices
+and pay our bills.

+## Mac: Homebrew 🍺
+
+The easiest way to install `Flutter` 
+on a Mac is using [Homebrew](https://brew.sh/).
+After installing Homebrew, 
+you can install `Flutter` 
+by running the command:
+
+```sh
+brew install --cask flutter
+```
+
+You should see something similar to:
