Question: will this work only for the mac on which you make the key?
Because I created the boot usb on my mac (pro13 2009) and if I start it on my friends computer (air 2011 I think) I get crossed out circle at boot. But on my mac I can boot from usb without problem.
Did you or your friend have firevault on?
I would suggest turning it off both when making the usb and when booting up on another computer with it.
I have made a usb on one computer and then booted up from it and installed onto another computer so it should work.
But I think maybe firevault could cause problems both for the usb and another computer if it is turned on.
I know this is a little off-topic, but there is a way to make a bootable DVD instead if your usb doesn't work. It's a bit more complicated and it will take longer for the DVD to boot up, but you could try it if your usb fails for whatever reason:
After downloading the Install OS X Mavericks.app file from the Mac App Store, run these 12 commands in Terminal to create a Mavericks.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 mavericks. This will not install a recovery partition. To do that, uncompress and run the script file https://dl.dropboxusercontent.com/u/13872235/Musings/Recovery%20Partition%20Creator%203.7.zip
hdiutil attach /Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app
hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Mavericks
hdiutil resize -size 8g /tmp/Mavericks.sparseimage
hdiutil attach /tmp/Mavericks.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/
hdiutil detach /Volumes/install_app
hdiutil detach /Volumes/install_build
hdiutil resize -size `hdiutil resize -limits /tmp/Mavericks.sparseimage | tail -n 1 | awk '{ print $1 }'`b /tmp/Mavericks.sparseimage
hdiutil convert /tmp/Mavericks.sparseimage -format UDTO -o /tmp/Mavericks
rm /tmp/Mavericks.sparseimage
mv /tmp/Mavericks.cdr ~/Desktop/Mavericks.iso
Did you use DiskmakerX version 3.0? It has a known issue, version 3.0.1 is OK I have heard. I used the Terminal method, which produced an USB stick that boots up another computer, gave up on DiskmakerX before that update was released.I dont have filevault turned on, and my friend erased his partition so he cant boot and change anything on his computer right now. He can only boot into recovery partition.
Creating dual layer dvd isnt an option here cause i dont have dual layer burner and friends air doesnt have cd/dvd drive...
I created usb 3 times and I even tryed creating it with diskmaker x and every time it would boot on my mac and not on his :/
I hope there is nothing wrong with his usb port or something..

I know this is a little off-topic, but there is a way to make a bootable DVD instead if your usb doesn't work.
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Assumptions: your destination USB drive is named Untitled.
Then you assume wrong. I was talking about a DVD not a USB.
createinstallmedia works with USBs, not DVDs.
My 15" Retina MacBook Pro still won't boot from usb flash drive (see also post #147 in this thread) and I don't understand why. Any suggestions would be greatly appreciated!
The only thing I can think of is if your USB drive is not partitioned to use GUID Partition Table.
It MUST be GUID in order to boot from the USB. You can use Disk Utility to verify the Partition Map Scheme.
I hope this helps. 😀
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

Done.
This is better than osxdaily's method (which should only be used for DP1 anyway, not DP4 or the GM):
To make a bootable USB of the GM, use this method:
Your 8 GB USB drive should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Mavericks.app and should be in your Applications folder.
Run this in terminal and wait about 20 minutes:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
You should see something like this:
Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.
You can then boot up from the USB by holding down the option key, then install the GM from the USB.
This is probably going to be the same for the public release.
Note that this will also install a recovery partition (which osxdaily's method doesn't do).
😎Thank you jakesteramma. I checked that and the USB-drive is using GUID partition table. It also states that the S.M.A.R.T. Status isn't supported. I don't know what that means, but could that be the culprit?
S.M.A.R.T. Status : Not Supported
Partition Map Scheme : GUID Partition Table
I've been reading in other places that there were some problems with USB 3.0 when the Retina Display MacBook Pro first came out. But when I check the USB drive with System Profiler it seems to be perfectly fine (as far as I can tell):

That's because you're on 10.6.8. It's a known issue right now and no fix at this time. (See my earlier post in this thread)
Hi,
I think I have something figured out. When I used the terminal method, it doesn't copy utilities over where it has startuup disk and disk utility. When I used diskmaker x 3.0.1, it will have the install os x mavericks and also a folder named utilities. The diskmaker x method can boot up and use disk utility or update/upgrade an existing or new drive. The terminal method does not have the folder "utilites" and is not able to boot up. For me, I was able to see on the startup (holding options on startup) the install usb disk, but saw the circle with a cross over it later, and cant continue on.
Diskmaker X method works for me. Not sure about other people.
