    mac os high sierra

    Apple released mac os 10.13 high sierra today to developers.

    Here is how to make the bootable usb for the first developer beta:

    Format an 8 GB (or preferably 16GB) USB3 drive which should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install macOS 10.13 Beta.app and should be in your Applications folder.

    Run this in terminal and wait about 20 minutes:

    sudo /Applications/Install\ macOS\ 10.13\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ 10.13\ Beta.app --nointeraction

    I was more interested by the new Macs they updated/announced today. iMac Pro looks awesome but reality is I'll just buy another Macbook.

    I was more interested in the improvement of safari.

    Re: mac os high sierra

    Beta 2 has been released today to developers.

    It comes as a delta update or full installer. The delta is quicker to download because it is smaller.

    But if you use the full installer you can make a bootable usb.

    The installer name has changed for beta 2 and so the command for making the bootable usb has changed too.

    So now for beta 2, format an 8 GB (or preferably 16GB) USB3 drive which should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install macOS High Sierra Beta.app and should be in your Applications folder.

    Run this in terminal and wait about 20 minutes:

    sudo /Applications/Install\ macOS\ High\ Sierra\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ High\ Sierra\ Beta.app --nointeraction

    Re: mac os high sierra

    It is released to the public now after 9 betas and 1 golden master. It is available on the mac app store. Note the final release has a higher build number than the golden master. (GM is build 17A362a whereas public release is 17A365).

    The installer name has changed for the public release and so the command for making the bootable usb has changed too.

    So format an 8 GB (or preferably 16GB) USB3 drive which should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install macOS High Sierra.app and should be in your Applications folder.

    Run this in terminal and wait about 20 minutes:

    sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --nointeraction

    The command for making a bootable usb has changed again. The old one can still be used but a simpler one is also available for High Sierra:

    sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

    How to make a bootable dvd of High Sierra
    (note it only boots as hfs+, not apfs):

    Make the bootable iso with the following commands:

    hdiutil create -o /tmp/HighSierra.cdr -size 5130m -layout SPUD -fs HFS+J

    hdiutil attach /tmp/HighSierra.cdr.dmg -noverify -mountpoint /Volumes/install_build

    sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build

    mv /tmp/HighSierra.cdr.dmg ~/Desktop/InstallSystem.dmg

    hdiutil detach /Volumes/Install\ macOS\ High\ Sierra

    hdiutil convert ~/Desktop/InstallSystem.dmg -format UDTO -o ~/Desktop/HighSierra.iso

    and then you can rename HighSierra.iso.cdr to HighSierra.iso.

    You can then use this to burn it to a dual layer dvd:

    sudo hdiutil burn /Users/YOURNAME/Desktop/HighSierra.iso

    where you replace "YOURNAME" with the username for the account you are logged into at the time.

    and then boot to startup manager with option key to select the dvd and install High Sierra from it.
