macOS Installation

Note: macOS support for the full range of functionality offered by the SDK is not yet complete. If you need support for R200 or the ZR300, legacy librealsense offers a subset of SDK functionality.

Note: The T265 tracking module is not yet fully supported on macOS via librealsense. Support is planned to be added in a future release.

Building from Source

  1. Install CommandLineTools sudo xcode-select --install or download XCode 6.0+ via the AppStore
  2. Install the Homebrew package manager via terminal - link
  3. Install the following packages via brew:

  • brew install cmake libusb pkg-config

  • brew install --cask apenngrace/vulkan/vulkan-sdk

    • on brew versions < 2.6 use brew cask install apenngrace/vulkan/vulkan-sdk instead

  • When setting CMake flag -DCHECK_FOR_UPDATES=ON

    • brew install openssl

Note librealsense requires CMake version 3.8+ that can also be obtained via the official CMake site.

  1. Generate XCode project:
  • mkdir build && cd build
  • sudo xcode-select --reset
  • cmake .. -DBUILD_EXAMPLES=true -DBUILD_WITH_OPENMP=false -DHWM_OVER_XU=false
  1. Build the Project
  • make -j2

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

Note: On some Mac systems you might encounter Could NOT find OpenSSL error (Usually when setting -DCHECK_FOR_UPDATES=ON), this can be worked-around by setting a global variable export OPENSSL_ROOT_DIR=`brew --prefix openssl`

Note: You can find more information about the available configuration options on this wiki page.

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
  1. Copy libusb-1.0.0.dylib and librealsense2.dylib to your application's Frameworks folder
