 For **macOS** users, latest versions of LightGBM are built with **gcc-8** and cannot be launched on systems with **gcc-7** and earlier. You should update your **gcc** compiler if you don't want to build from sources or install LightGBM 2.1.1 which is the last version built with **gcc-7**.

This means that you won't need to install the **gcc** compiler anymore. Instead of that you'll need to install the **OpenMP** library, which is required for running LightGBM on the system with the **Apple Clang** compiler. You can install the **OpenMP** library by the following command: ``brew install libomp``.
