Give it some time, and your volume will soon be loaded up with not just the macOS installer but also an external recovery partition that may come in handy if your hard drive dies and you’re away from an Internet connection.
#INSTALL DISK CREATOR BEN SLANEY INSTALL#
The command will erase the disk and copy the install files over. Sudo /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/Untitled -applicationpath /Applications/Install macOS Sierra.app -nointeraction

Assuming that you have the macOS Sierra installer in your Applications folder and you have a Mac OS Extended (Journaled)-formatted USB drive named “Untitled” mounted on the system, you can create a Sierra install drive by typing the following command into the Terminal. If you don’t want to use the Install Disk Creator, Apple has included a terminal command that can create an install disk for you. This should only take a few minutes on a USB 3.0 flash drive in a modern Mac, though using USB 2.0 or other interfaces will slow things down. A progress bar across the bottom of the app will tell you how far you have to go, and a pop-up notification will let you know when the process is done.
Once you’re ready to go, click “Create Installer” and wait. You can navigate to a different one if you want, and you can also pick from among all the storage devices and volumes currently connected to your Mac through the drop-down menu at the top of the window. Install Disk Creator will automatically detect macOS installers on your drive and suggest one for you, listing its icon along with its path. In any case, it will work just fine for our purposes. This app is basically just a GUI wrapper for the terminal command, so it should be possible to make install disks for versions of OS X/macOS going all the way back to Lion. Once you’ve obtained all of the necessary materials, connect the USB drive to your Mac and launch the Install Disk Creator.

The macOS 10.12 Sierra installer from the Mac App Store in your Applications folder.For newer Macs, use a USB 3.0 drive-it makes things significantly faster. An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive.We’ve created Sierra USB stick from both El Capitan and Sierra, but your experience with other versions may vary. A Mac that you have administrator access to, duh.There’s the super easy way with the graphical user interface and the only slightly less easy way that requires some light Terminal use. Whatever the reason, you’re in luck, because it’s not hard to make one.Īs with last year, there are two ways to get it done. Or, maybe you need a recovery disk for older Macs that don’t support the Internet Recovery feature. For instance, if you find yourself doing multiple installs, a USB drive may be faster than multiple downloads (especially if you use a USB 3.0 drive). Things have proceeded remarkably smoothly since version 10.7 switched to download-only installers, but there are still good reasons to want a reliable old USB stick. It was 2009 when Apple last released a new operating system on physical media.
