I made a bootable Sierra USB but it can't detect it as a startup disk!
I created a bootable macOS Sierra to USB drive 16GB with Terminal method :
" sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/sierra --applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction "
This method not detected as a startup disk if I try to chose it.
I know I can booted it from ALT (Option) at startup but I have problem on my MacBook I can't do it...
The only method I can be reset my OS is from Startup Disk.
Disk Maker work great it Detected on Startup Disk but is to slow for copy if have a another solution from Terminal or another apps to do bootable please
Es esta una buena pregunta?
