To make a USB drive installation, back up your data. Formatted installation loses hard drive data. Remember

To download the installer:

Download the full "MacOS Sierra" from the APP store

the installer, which is stored in the application (/applications) after it has been downloaded folder. Please note that you must not start the install MacOS Sierra program directly at this time because the installer will be removed once the installation is complete. At a minimum, you should finish installing the standalone installation media before starting the program installation.

prepare a standalone installation disk media: You need a mobile storage device with a capacity of at least 8GB, such as a USB flash drive, a removable hard disk or an SD card, insert it into your Mac, and start the disk utility to "erase" the media, and back up the important data on the media before wiping it out. The drive letter name is named "Untitled" format [mac OS Extended (journaled)]//mac OS Extensions (journaled)].

To create an installation disk from the Terminal command: Open the Terminal , execute the following command at the command line and enter your OS X Administrator login password when prompted for the password.

Code:

• Sudo/applications/install\ macos\ Sierra.app/contents/resources/createinstallmedia--volume/volumes/ Untitled--applicationpath/applications/install\ macos\ sierra.app--nointeraction

  • (note here that each version corresponds to a different software name, such as  2014 years of os x Yosemite; 2015 OS X El Capitan; today's MacOS Sierra, different versions of the software name correspond to different versions of the path name, such as 2014 OS X Yosemite The path is: sudo/applications/install \ os\ x\ yosemite.app /contents/resources/createinstallmedia--volume/volumes/ Untitled--applicationpath/applications/install\ os\ x\ yosemite.app -- Nointeraction any version that modifies the pink font portion is the current path, and the pink font is viewed by opening the Finder, selecting the application, locating the installation package , Commond + I, name and extension, which is the installation package path )

Copy the code directly, and then command+v paste it to "terminal".

Finish Making: If everything is OK, the terminal interface will display Erasing disk:0% ... 10% ... 20% ... , and finally finished the production. Once you're done, you can use this media to start any MacOS Sierra-compatible Mac (you need to insert the media on the target Mac and then hold the option key on the boot ) to start the MacOS Sie installation tour of RRA.

Here is a reminder: After clicking option to select the USB flash drive installation, after entering the disk tool can be selected to format the hard disk clean installation
