+
+#### Install required QT packages
 
-#### Shared library
+To see the available QT versions run:

 ### 4. Build USB-SD-Creator
 
 Assuming the repo is in your home directory
 
 ```
 cd ~/usb-sd-creator
+```
 
-./osx_build.sh
+#### Debug build
+```
+cmake -S . -B build -D CMAKE_PREFIX_PATH="/Users/$USER/Qt/6.7.2/macos" && cmake --build build
 ```
 
-If building again cleanup using:
+#### Release build
 ```
-./osx_clean.sh
+cmake --preset release -D CMAKE_PREFIX_PATH="/Users/$USER/Qt/6.7.2/macos" && cmake --build --preset release
 ```
 
 ### 5. Run USB-SD-Creator
 
 #### Open the app
 
-Simply double click the app from a finder window in the root of the repo: `LibreELEC USB-SD Creator`
+Simply double click the app from a finder window in the `build` folder in the repo: `build/LibreELEC USB-SD Creator`
 
 #### Command line
 
 Run the app from the command line, that will prompt for a password:
 ```
-./LibreELEC\ USB-SD\ Creator.app/Contents/MacOS/LibreELEC\ USB-SD\ Creator
+./build/LibreELEC\ USB-SD\ Creator.app/Contents/MacOS/LibreELEC\ USB-SD\ Creator
 ```
 
 **Or:**
 
 Run the app from the command line using sudo
 
 ```
-sudo ./LibreELEC\ USB-SD\ Creator.app/Contents/MacOS/LibreELEC\ USB-SD\ Creator
+sudo ./build/LibreELEC\ USB-SD\ Creator.app/Contents/MacOS/LibreELEC\ USB-SD\ Creator
+```
+
+### 6. Debugging USB-SD-Creator
+
+#### Using QT Creator
+
+If you need to, install QT Creator:
+
+```
+brew install --cask qt-creator
 ```
+
+Then simply open CMakeLists.txt in QT Creator
+
+#### Using XCode
+
+Build the xcode project, and open the project file in Xcode, located in the build folder (note you may need to clear any previous build files before genreating for XCode):
