+1. Install CommantLineTools `sudo xcode-select` or download XCode 6.0+ via the AppStore
 2. Install the Homebrew package manager via terminal - [link](http://brew.sh/)
 3. Install the following packages via brew:
-  * `brew install libusb pkg-config`
-  * `brew install homebrew/core/glfw3`
-  * `brew install cmake`
+  * `brew install cmake libusb pkg-config`
+  * `brew cask install vulkan-sdk`
 
-**Note** *librealsense* requires CMake version 3.8+ that can be obtained via the [official CMake site](https://cmake.org/download/).

 4. Generate XCode project:
   * `mkdir build && cd build`
   * `sudo xcode-select --reset`
   * `cmake .. -DBUILD_EXAMPLES=true -DBUILD_WITH_OPENMP=false -DHWM_OVER_XU=false -G Xcode`
-5. Open and build the XCode project
+5. Build the Project
+  * `make -j`
 
 > **Note:** On some Mac systems you might encounter `ld: library not found for -lusb-1.0` error (either in the terminal during make or in XCode) This can be worked-around by setting environment variable: `/bin/launchctl setenv LIBRARY_PATH /usr/local/lib`
 
 ## What works?
 * SR300, D415 and D435 will stream depth, infrared and color at all supported resolutions
 * The Viewer, Depth-Quality Tool and most of the examples should work
 
+## Packaging your application
+1. librealsense requires libusb to be bundled in the application. To fix the real-time linking, use `install_name_tool`
+```
+install_name_tool -change /usr/local/opt/libusb/lib/libusb-1.0.0.dylib @rpath/libusb-1.0.0.dylib librealsense2.dylib
+```
+2. Copy `libusb-1.0.0.dylib` and `librealsense2.dylib` to your application's `Frameworks` folder
+
 ## What are the known issues?
 * Changing configurations will often result in a crash or the new configuration not being applied (WIP)
