downloaded high sierra from the app store, then tried creating a USB installer using Terminal but i get the following error:
# sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/My-USB-Name/ --applicationpath /Applications/Install\ macOS\ High\ Sierra.app /Applications/Install macOS High Sierra.app does not appear to be a valid OS installer application.
the high sierra directory is present, im able to press
tab on my keyboard to auto-complete the paths.
after googling the error, i found this reddit answer but im not sure what he's talking about or why it should be done, so i havent tried it.
"Move the directory /macOS Install Data (which is downloaded after you run through the installation once) to be Install macOS High Sierra.app/Contents/SharedSupport"
the USB im using is 64Gb and freshly formated using Disk Utilities.
these answers didnt help solve my issue. i think i have the "stub" in my applications folder as the high sierra .app is only 14mb.
i cant figure out how to install the full high sierra installer
