【macOS】制作 Ubuntu 启动 U 盘

创建 .dmg

我们知道DMG格式是Mac OS上常用的打包格式文件，需要把下载的Ubuntu安装文件(.iso)转换成(.dmg)格式的文件，方便在Mac OS上面进行操作，转换命令

 hdiutil convert -format UDRW -o ubuntu.iso ubuntu-20.04.3-desktop-amd64.iso

-format：为生成文件的权限，UDRW：表示转换成有read/write权限的镜像

$ diskutil list
...
/dev/disk5 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *128.0 GB   disk5
   1:               Windows_NTFS                         128.0 GB   disk5s1

$ diskutil unmountDisk /dev/disk5
Unmount of all volumes on disk5 was successful

再次使用***diskutil*** 命令就不会再展示***/dev/disk4*** 了
