1. 安装依赖

• 安装CUDA

下载地址：https://developer.nvidia.com/cuda-toolkit-archive，本文采用的是CUDA 7.5版本。下载安装之后，需要配置环境变量，编辑/etc/profile'，添加PATH=$PATH:/Developer/NVIDIA/CUDA-7.5/bin`。

• 安装其它的依赖

通过Homebrew安装所需要的其它依赖，其它依赖有gflags，snappy，glog，hdf5，lmdb ，opencv3，boost，leveldb ，protobuf，webp（运行mnist数据集会用到）。命令如下：

# 安装软件
$ brew install software

# 创建软件链接，有的需要，例如protobuf，opencv3，opencv3需要--force
$ brew link software --force

2. 安装caffe

在Github上下载caffe源码，地址为：https://github.com/BVLC/caffe，下载后在caffe根目录创建build文件夹，将Makefile.config.example文件名改为Makefile.config，修改Makefile.config文件，修改如下：

将
# CPU_ONLY := 1
改为
CPU_ONLY := 1

将
# USE_OPENCV := 0
改为
USE_OPENCV := 1

将
# OPENCV_VERSION := 3
改为
OPENCV_VERSION := 3


将下面两行
# BLAS_INCLUDE := /path/to/your/blas
# BLAS_LIB := /path/to/your/blas

改为：
BLAS_INCLUDE := /System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Versions/Current/Headers
BLAS_LIB := /System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Versions/Current

执行make -j，看到下面的内容说明安装caffe成功。
