Recommended Posts

--First Option / Terminal


Open a terminal and do the following

 

diskutil list
[color=#AAAAAA]...
/dev/disk[/color][color=#FF0000]2[/color]
[color=#AAAAAA]   #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:     FDisk_partition_scheme                        *16.0 GB    disk2
  1:                 DOS_FAT_32 [/color][color=#FF0000]SANDISK                 16.0 GB[/color][color=#AAAAAA]    disk2s1
...[/color]

Find your USB stick in the output

 

diskutil unmountDisk /dev/disk[color=#FF0000]2[/color]
[color=#AAAAAA]Unmount of all volumes on disk2 was successful[/color]
sudo dd if=[color=#FF0000][drag and drop the raw file in terminal][/color] of=/dev/rdisk[color=#FF0000]2[/color] bs=1m

Ela instala apenas o sistema original, sem modificações. Você precisa instalar as kexts necessárias para o seu hardware, independente de ser laptop ou desktop. As kexts e boot loader incluídas na imagem servem apenas para o boot do instalador e boot inicial do sistema através do pen drive.
