# 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](https://github.com/IntelRealSense/librealsense/tree/legacy) offers a subset of SDK functionality.

|
## 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](http://brew.sh/)
|
||
|
|
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](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`
|
||
|
|
5. 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](https://github.com/IntelRealSense/librealsense/wiki/Build-Configuration).

## 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
