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
