前言

我有一台Mac，装有OS X和Windows两系统，因Windows和OS X都能读写exFAT分区，

故若在Machintosh HD和Windows HD之间开辟一个exFAT分区，可以作为共享文件区。

我在OS X中用磁盘工具对Machintosh HD进行分区，在Machintosh HD和Windows HD之间开辟一个exFAT分区。

重启启动时，我按住了option，之后出现的启动选项中没有Windows。这因为刚才给磁盘分了区才导致的。

解决

重启MAC ，按住COMMAND+R进入恢复模式，打开Terminal

csrutil disable #关闭rootless

修改完，重启MAC，打开终端

sudo fdisk -e /dev/disk0
