    Does anyone know if there is a USB stick or CD version of the download available ? (I'm in the UK)

    What is the filesize for the OS download?

    I'm currently using Lion on my 2011 MAc mini. Not sure how I can get hold of the upgrade (I couldn't get the Mavericks one) as the file size is probably too big.
    I have 3GB monthly usage cap on my broadband so can't download more than that in a month. Also last time I downloaded the ligthroom upgrade which was about 1GB it took about 24 hours to download so if more than 3GB it could take a whole weekend just to download....
    So ideally I would want to instal vua USB stick or CD, otherwise I'll stick with Lion.

    Thanks.

    Forget CD.... as far as I know there's no usb option provided by Apple. Can you download it from elsewhere? The installation file is about 5GB.

    If you can download it on a mac, you can use DiskMakerX www.diskmakerx.com

    Alternatively you can download it to your Applications Foledder and go into terminal and type:

    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X Yosemite.app --nointeraction

    That's for a usb but contains errors regarding the spaces in Install OS X Yosemite.app which should be written with the \ and so it should be

    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction

    For more details on this see this thread: http://forums.macrumors.com/showthread.php?t=1801963

    A cd is too small.

    For an optical disc you need a dual layer dvd.

    Here is how you can make a bootable dvd of the yosemite installer.

    After downloading the full Yosemite installer app from the Mac App Store, run these 14 commands in Terminal to create a Yosemite.iso file and then burn it to a dual layer DVD with Disk Utility. You may then boot up from it by holding the option key down and then install Yosemite.

    hdiutil attach /Applications/Install\ OS\ X\ Yosemite.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

    hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Yosemite

    hdiutil resize -size 8g /tmp/Yosemite.sparseimage

    hdiutil attach /tmp/Yosemite.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build

    rm /Volumes/install_build/System/Installation/Packages

    cp -rp /Volumes/install_app/Packages /Volumes/install_build/System/Installation/

    cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/install_build

    cp -rp /Volumes/install_app/BaseSystem.dmg /Volumes/install_build

    hdiutil detach /Volumes/install_app

    hdiutil detach /Volumes/install_build

    hdiutil resize -size `hdiutil resize -limits /tmp/Yosemite.sparseimage | tail -n 1 | awk '{ print $1 }'`b /tmp/Yosemite.sparseimage

    hdiutil convert /tmp/Yosemite.sparseimage -format UDTO -o /tmp/Yosemite

    rm /tmp/Yosemite.sparseimage

    mv /tmp/Yosemite.cdr ~/Desktop/Yosemite.iso

    This works perfectly and no need to download any extra apps. For those who need a bit of help with this. First open Disk Utility and format a USB flash drive (at least 8 GBs) with a GUID partition table and set format to Mac OS Extended (Journaled). Leave the name as Untitled. Then open terminal (in Utilities) and copy and paste the line posted above.

    another correction to that line of code:

    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction

    also make sure the usb drive is named Untitled

    (notice the "\" before each space in "Install\ OS\ X\ Yosemite.app", it is important.)

    Good point. I was going to check it, but I was trusting you. ;) I normally just hit tab to complete, instead of trying to whack in the backslashes correctly.

    I copy and pasted it, from an another place, where the OP there apparently left it out. I tried to reply to let them know, but the Apple Forum won't let me see that post when I am logged in. I corrected the first one in my first response.
