( stupidly forgot to select the 'show all devices' option so I was clicking the USB drive and formatting it to macOS extended journaled format but did see the option to to select the scheme - GUID partition map. The problem I think was because I did not choose the scheme to be GUID partition Map when I was formatting the USB. I did it by booting the MacBook in recovery mode and installed the OS on the USB using the disk utility. I have managed to install the OS on the USB now. ¿What does Disk Utility's Device View say about your drives? is the USB stick showing when you begin? Is the MacOS Volume on the USB-stick Mounted when you begin? Is it the correct type?ĭirectory tree: /Applications/Install\ macOS\ High\ Sierra.appĪre you sure you are copying the entire string from the article and pasting it straight into Terminal?ĭo you have any text replacement software that might be altering the string? This makes it seem like something is wrong with the USB-stick, or perhaps it is not already Mounted when you start the process. Then it tries to look at the already-Mounted USB-stick, by Volume-name provided, and fails. Volumes/MyVolume -applicationpath is not a valid volume mount point. If your Installer image were completely clobbered or absent, "command not found" is the likely outcome. Reaches into the newly-downloaded Installer image in the current top-level /Applications folder to get the command to be executed. Sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia
