-### Installation
-
-$ git clone https://github.com/cagnulein/qdomyos-zwift.git
+### Installation from source

 $ sudo apt upgrade && sudo apt update # this is very important on raspberry pi: you need the bluetooth firmware updated!

-$ sudo apt install libqt5bluetooth5
+$ sudo apt install git libqt5bluetooth5 libqt5widgets5 libqt5positioning5 libqt5xml5 qtconnectivity5-dev qtpositioning5-dev libqt5charts5-dev libqt5charts5 qt5-default

-$ sudo hciconfig hci0 leadv 0
+$ git clone https://github.com/cagnulein/qdomyos-zwift.git
+
+$ cd src
+
+$ qmake
+
+$ make -j4

 $ sudo ./qdomyos-zwift

+### MacOs installation
+
+You will need to (at a minimum) to install the xcode Command Line Tools (CLI) thanks to @richardwait
+https://developer.apple.com/download/more/?=xcode
+
+Download and install http://download.qt.io/official_releases/qt/5.12/5.12.9/qt-opensource-mac-x64-5.12.9.dmg and simply run the qdomyos-zwift relase for MacOs
+
 ### Tested on

-Raspberry PI 0W and Domyos Intense Run
+- Raspberry PI 0W and Domyos Intense Run
+
+- MacBook Air 2011 and Domyos Intense Run
+
+- Raspberry 3b+ and Domyos T900C
+
+- Raspberry 3b+ and Toorx TRX Route Key
+
+### No gui version
+
+run as
