一、 Mac下将ISO写入U盘可使用命令行工具dd,操作如下:
1、找出U盘挂载的路径,使用如下命令:diskutil list
2、将U盘unmount(将N替换为挂载路径):diskutil unmountDisk /dev/disk[N]
3、写入U盘:sudo dd if=iso路径 of=/dev/rdisk[N] bs=1m rdisk 中加入r可以让写入速度加快
二、具体操作示例:
1. 将iso转换成dmg 转iso 用
UDRW 替换为 UDTO
1 lapommedeMacBook-Pro:~ lapomme$ sudo hdiutil convert -format UDRW -o /linux.dmg kali.iso 2 Password: 3 正在读取Master Boot Record(MBR:0)… 4 正在读取Kali Live (Apple_ISO:1)… 5 正在读取(Windows_NTFS_Hidden:2)… 6 ............................................................................ 7 正在读取(DOS_FAT_12:3)… 8 .............................................................................. 9 已耗时:10.178s 10 速度:288.3M 字节/秒 11 节省:0.0% 12 created: /linux.dmg
2. 查看u盘盘符
1 lapommedeMacBook-Pro:~ lapomme$ diskutil list 2 /dev/disk0 (internal, physical): 3 #: TYPE NAME SIZE IDENTIFIER 4 0: GUID_partition_scheme *251.0 GB disk0 5 1: EFI EFI 209.7 MB disk0s1 6 2: Apple_CoreStorage Macintosh HD 250.1 GB disk0s2 7 3: Apple_Boot Recovery HD 650.0 MB disk0s3 8 /dev/disk1 (internal, virtual): 9 #: TYPE NAME SIZE IDENTIFIER 10 0: Apple_HFS Macintosh HD +249.8 GB disk1 11 Logical Volume on disk0s2 12 E2BD4617-5A22-46A9-A6F4-D54E3EE92BBC 13 Unencrypted 14 /dev/disk2 (external, physical): 15 #: TYPE NAME SIZE IDENTIFIER 16 0: FDisk_partition_scheme *62.0 GB disk2 17 1: DOS_FAT_32 UNTITLED 1 62.0 GB disk2s1 18 /dev/disk3 (disk image): 19 #: TYPE NAME SIZE IDENTIFIER 20 0: FDisk_partition_scheme +3.1 GB disk3 21 1: 0x17 3.0 GB disk3s1 22 2: DOS_FAT_12 NO NAME 110.1 MB disk3s2
3. 取消挂载U盘
1 lapommedeMacBook-Pro:~ lapomme$ diskutil umountDisk /dev/disk2 2 Unmount of all volumes on disk2 was successful
4. 用dd命令写入U盘
说明:
(1)sudo dd if=源路径 of=/dev/r卷标 bs=1m [‘r’ 会让命令执行加快一点] [‘bs’为一次填充的容量]
(2)获取映像名称和完整路径可以直接将文件拖入终端,即在终端中显示
1 lapommedeMacBook-Pro:~ lapomme$ sudo dd if=/linux.dmg of=/dev/rdisk2 bs=1m 2 2934+1 records in 3 2934+1 records out 4 3076767744 bytes transferred in 149.567568 secs (20571089 bytes/sec)
5. 查看磁盘进度,可以用iostat命令查看磁盘写入状态
1 lapommedeMacBook-Pro:~ lapomme$ iostat -w 2 2 disk0 disk2 disk3 cpu load average 3 KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us sy id 1m 5m 15m 4 102.71 25 2.49 598.70 0 0.15 24.76 1 0.02 5 4 90 2.04 1.71 1.69 5 512.00 48 23.93 1024.00 24 23.93 0.00 0 0.00 1 3 96 2.11 1.74 1.69 6 473.00 26 11.99 1024.00 12 11.98 0.00 0 0.00 3 3 93 2.11 1.74 1.69 7 491.68 50 23.99 1024.00 24 23.99 0.00 0 0.00 24 8 68 2.11 1.74 1.69
6. 操作完毕后将U盘弹出
1 lapommedeMacBook-Pro:~ lapomme$ diskutil eject /dev/disk2 2 Disk /dev/disk2 ejected
