It is the primary operating system for Apples Mac computers.
However, terminal did not request password but rather looped directly back to original prompt. macOS is a Unix operating system developed and marketed by Apple Inc. If you're using a Mac with OS X 10.5 (Leopard) or older, you must first purchase a copy of OS X 10.6 (Snow Leopard) and install it on your Mac before you'll be able to update Safari.

This time, when Terminal looped back to the original prompt, I re-entered the Command and hit enter. This wikiHow teaches you how to update Safari and get rid of the 'This version of Safari is no longer supported' messages. I hit Ctrl-C and closed out, then tried again but it still did not work. 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.
