Making USB Boot for MAC

[Xanstrider770]

Hi,

 

Hoping someone can help me with a MAC issue lol. I would like to restore a .dmg onto a USB key so I can use it as a boot disk. I would like to put snow leopard on the USB. Im using El Captain at the moment. When i go into Disk Utility I cant make a restore USB disk. On Snow Leopard i could do this with disk utilitys. Is there another way to do this on El Captain? Thanks

I use this for all my boot drives

i'll go with the premise that you have downloaded El Capitan and it's in your application folder

open disk utility

format USB disk in MacOS extended journaled

open terminal

input this command:

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

(replace Untitled with your USB's name or name your USB Untitled when formatting)

enter password

wait

done

Thanks for the info!

 

Just wondering though, if I already have El Capitan installed. Would making a snow leopard USB boot be any different? What would the command line be? Or which bit would I need to change for it to access the Snow Leopard .dmg

Just need to make a Snow Leopard USB boot, got the .dmg for snow leopard and jusing a mac that is running El Captain.

 

Thanks

same instruction just replace the path of el capitan with the path of snow leopard, to make it easy just put the dmg in  the application folder and instead of:

/Applications/Install\ OS\ X\ El\ Capitan.app

write:

/Applications/Install\ OS\ X\ Snow\ Leopard.dmg

(the name of the dmg should be "Install OS X Snow Leopard.dmg")

 

If that doesn't do it, the disk utilty method should still work. Maybe you should retry it.
