Create bootable Mac OS Sierra installer flash drive

Apple recently announced Mac OS Sierra at WWDC which is currently available as a Developer Preview and soon will be available as Public Beta.

While most of you may prefer installing it directly by upgrading their current EL Capitan setup others may want to clean install or create a bootable flash drive to install it on multiple Mac or have a USB installer instead.

You need to have a flash drive that is 8GB or above.

All you have to do is open Terminal and enter this command and change the <usbmedia> with you flash drive name.

(Be careful while choosing your flash drive as this process will erase the data on that specific volume)

sudo /Applications/Install 10.12 Developer –volume /Volumes/<usbmedia> –applicationpath /Applications/Install 10.12 Developer  

You should see something like this in your Terminal.

Ready to start.  
To continue we need to erase the disk at /Volumes/Flash Drive.  
If you wish to continue type (Y) then press return: Y  
Erasing Disk: 0%… 10%… 20%… 30%…100%…  
Copying installer files to disk…  
Copy complete.  
Making disk bootable…  
Copying boot files…  
Copy complete.  

You can now reboot your Mac and hold the option key to switch to the flash drive that contains the installer

    Hey! Nice, simple tutorial.
    Can you tell me how to install rutorrent as well and get it to work with rtorrent. The tuts online now are pretty outdated. Would love for a updated one from you.

    • I will publish one guide soon on “How to use RuTorrent with RTorrent”, thank you for the suggestion.

      • Ragul

        Thanks, I will be on the lookout for them 🙂

        • I will notify you when it will be published.

            Any word on the RuTorrent guide?

          • I was a bit busy, I am working on that, I am trying to find a guide that works on all the Raspberry Pi model that can handle RTorrent, I will publish the guide this week and let you know.

            Thank you for commenting.

            Sounds good, thanks! Wasn’t sure if I just was missing it, and having a senior moment with the search tool. 🙂

            I know your a busy man, and I don’t mean to harass you, but any update on posting the rutorrent guide?

          • I am sorry for the delay. I am trying not find the most efficient way to do it with the least amount of steps, so it can be easy to everyone and work on every Raspberry Pi. I will try my best to publish the post in this month.
