Masalah unetbootin di Mac untuk USB boot

Masalah unetbootin kadang jadi kadang tidak, so solution yang cepat ialah gunakan dd.

Kenal pasti USB disk kita dia mac dengan arahan :

Yusof$ diskutil list
/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *240.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:          Apple_CoreStorage Macintosh SSD           239.2 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
/dev/disk1 (internal, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                  Apple_HFS Macintosh SSD          +238.8 GB   disk1
                                 Logical Volume on disk0s2
                                 CBE9D533-87EA-4C43-87EC-C6D4AB34B87E
                                 Unencrypted
/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *15.5 GB    disk2
   1:                        EFI EFI                     209.7 MB   disk2s1
   2:       Microsoft Basic Data UNTITLED                15.3 GB    disk2s2

/dev/disk2 adalah external / usb stick so, kita unmount gunakan arahan :

Yusof$ diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful

 Kemudian, dapatkan ISO / img yang kita nak gunakan, terus dd ke usb dengan bergaya.

Yusof$ sudo dd if=FD12FULL.img of=/dev/disk2s2
1048576+0 records in
1048576+0 records out
536870912 bytes transferred in 779.402557 secs (688824 bytes/sec)

 Selepas selesai dalam 10 minit macam tu, cucuk ke server dan terus boot dari usb stick. Kudos!

Tutorial ini adalah semasa ujian update bios/firmware Supermicro menggunakan FreeDOS :)
