How to create a bootable macOS Sierra USB installer

[Carter]

I've done up a document on how to create a bootable macOS Sierra 10.12 Developer Preview USB installer here How to create a bootable macOS Sierra USB installer

Basically the same command-line as previous versions then.

 

Sierra (Developer Preview)

sudo /Applications/Install\ 10.12\ Developer\ Preview.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ 10.12\ Developer\ Preview.app --nointeraction

 

El Capitan

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

 

Yosemite

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

 

Mavericks

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

Yup!

[Arthur]

Now that Sierra has been released...

 

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction

 

... or use Install Disk Creator.

does anyone know where I can download an ISO of sierra

You need to use the App Store, download the update, but don't install it (it deletes the app after install). Use the script above for USB, or you can use the --volume volumepath switch to specify a recordable DVD path (I believe, not tried it recently).

Do you actually need an ISO or just the installer app?

 

This is the Mac App Store download page for Sierra...

Updated mine from mavericks to el capitan yesterday and then discovered sierra this morning. updated again and it went a bit weird (locking my screen every few seconds, warning me apps weren't working) so installing from usb now. thanks for reminding me disk creator existed
