http://code.google.com/p/git-osx-installer上也提供了一个Git的图形化客户端：OpenInGitGui，可以从这里获得，OpenInGitGui十分小巧，下载解压后也只有16K，OpenInGitGui不用安装，双击即可使用，OpenInGitGui刚启动时，会记录打开过的资源库。

github使用SSH链接，需要设置SSH

1.检查SSH key

cd ~/.ssh

2.备份已有的key，（如果有的话）

mkdir key_backup

mv id_rsa* key_backup

3.生成SSH key

$ ssh-keygen -t rsa -C x.kristain@gmail.com

Generating public/private rsa key pair.

Enter file in which to save the key (/Users/kristain/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in yes.

Your public key has been saved in id_rsa.pub.

The key fingerprint is:

9e:10:27:3c:7c:64:b9:12:b3:7f:a8:1a:8e:59:26:ea x.kristain@gmail.com

The key's randomart image is:

+--[ RSA 2048]----+

|                 |

|                 |

|                 |

|         .       |

|      . S ..     |

|     . oE=o..    |

|      . +o+..    |

|       ..+.+..   |

|         oOB=+o  |

+-----------------+

4.将SSH key添加到GitHub

登录到GitHub页面，Account Settings->SSH Public Keys->Add another key

将生成的key(id_rsa.pub文件）内容copy到输入框中，save。

5.测试链接

$ ssh -T git@github.com

Hi kristain! You've successfully authenticated, but GitHub does not provide shell access.

出现上述提示信息说明连接成功（github并不提供shell登陆但已经连接成功）

三、设置个人信息

$ git config --global user.name "kristain"

$ git config --global user.email x.kristain@gmail.com
