However, terminal did not request password but rather looped directly back to original prompt. This time, when Terminal looped back to the original prompt, I re-entered the Command and hit enter. A file named Install macOS Sierra downloads to your Applications folder. Click the Download button on the macOS Sierra page. Search the App Store for macOS Sierra, or go directly to the macOS Sierra page. Then follow these steps: Open the App Store app on your Mac. I hit Ctrl-C and closed out, then tried again but it still did not work. Before upgrading, it's a good idea to back up your Mac.

That said, I've downloaded macOS Sierra and just in case I need it, in the future, I tried to create a bootable usb in Terminal, as shown in the video below and many others but it did not appear to work.Īt the Terminal prompt, I entered the Command (sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/MyInstallerName -applicationpath /Applications/Install\ macOS\ Sierra.app) and hit enter, then entered my password, as requested but instead of beginning, Terminal looped back and gave me the original prompt, again. Now, working on the MBP first, it's my understanding that since Lion 10.7.5 came pre-loaded, I can always do OSX Recovery, if needed so no bootable necessary, there. I saved all my important files and folders from both the Mini and MBP to an external HD, which is connected to the Mini. Download the Installer from Apple directly to the computer that you want to install the new OS X onto.
