-### Installation
+### Installation from source
+
+$ sudo apt update && sudo apt upgrade # this is very important on raspberry pi: you need the bluetooth firmware updated!
+
+$ sudo apt install git libqt5bluetooth5 libqt5widgets5 libqt5positioning5 libqt5xml5 qtconnectivity5-dev qtpositioning5-dev libqt5charts5-dev libqt5charts5 qt5-default
 
 $ git clone https://github.com/cagnulein/qdomyos-zwift.git
 
-$ sudo apt upgrade && sudo apt update # this is very important on raspberry pi: you need the bluetooth firmware updated!
+$ cd src
 
-$ sudo apt install libqt5bluetooth5
+$ qmake
 
-$ sudo hciconfig hci0 leadv 0
+$ 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
+
+
+### Your machine is not compatible?
+
+Open an issue and follow these steps!
+
+1. first of all you need an android device (phone or tablet)
+2. you need to become developer on your phone https://wccftech.com/how-to/how-to-enable-developer-options-on-android-10-tutorial/
+3. Go to Settings
+4. Go into developer options
+5. Enable the option Enable Bluetooth HCI snoop log
+6. restart your phone
+7. open your machine app and play with it collecting inclination and speed
+8. Disable the option Enable Bluetooth HCI snoop log
+9. on your phone you should have a file called btsnoop_hci.log
+10. attach the log file in a new issue with a short description of the steps you did in the app when you used it
+
+### No gui version
+
+run as
+
+$ sudo ./qdomyos-zwift -no-gui
