如何解码要在 Mac OS X 上安装哪个版本的 Golang？
How to decode which version of Golang to install on Mac OS X?
在官方 Golang 网站上，在 Get Started 部分，我们读到：
Install the Go tools
If you are upgrading from an older version of Go you must first remove
the existing version.
Linux, Mac OS X, and FreeBSD tarballs
Download the archive and extract it into /usr/local, creating a Go
tree in /usr/local/go. For example:
tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz
Choose the archive
file appropriate for your installation. For instance, if you are
installing Go version 1.2.1 for 64-bit x86 on Linux, the archive you
want is called go1.2.1.linux-amd64.tar.gz.
(Typically these commands must be run as root or through sudo.)
Add /usr/local/go/bin to the PATH environment variable. You can do
this by adding this line to your /etc/profile (for a system-wide
installation) or $HOME/.profile:
export PATH=$PATH:/usr/local/go/bin
当我们访问 Downloads 部分时，我们会看到许多选项：
go1.4.2

I 运行 Mac OS X Yosemite，版本 10.10.3，配置如下：
- 处理器：2.8 GHz Intel Core i5
- 内存：8 Go 1600 MHz DDR3
- 显卡：Intel Iris 1536 Mo
我应该安装哪个版本的 Go？
最重要的是，为什么（这样我以后可以自己做决定）？
你会想要这个：
go1.4.2.darwin-amd64-osx10.8.pkg Installer OS X 10.8+ 64-bit
注意关键部分：amd64（64位），OS X 10.8+（其中10.10.3满足）。它是 GUI 安装程序，可自动执行大量工作。
Mac OS X常被称为"darwin"，这是对低级OS.
