Followed the above steps and created a USB installer. I'm now clean installing Mavericks. I had previously updated from the DP but feel I should have a fresh start.
 
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).

can you explain how the recovery partition works?
 
Yeah. If you hold down the option key when booting up and then you can use it to reinstall the system, restore from backup or run disk utilities.
 
Absolutely, it is always best to obtain the file directly from Apple if you can. However, not all of us are registered developers (myself included). Regardless, I was able to find a download of the GM that is bit-for-bit identical to the download available through the Mac App Store. As long as you use some common sense and download from trusted sources, you will be fine.

P.S. - Please do NOT contact me asking for download links.

You aren't suggesting that it is common sense to download and use software in violation of Apple's License Agreements surely? :confused:

You should sign up for the Developer Program and download it from Apple. Only by that method can you be sure that you are getting the correct file and are not violating the License Agreement.

I've been using my downloaded copy for almost 2 weeks with no issues. I have verified with multiple sources that the file I obtained is bit-for-bit IDENTICAL to the file given to registered developers. When Mavericks is released on the Mac App Store, I will gladly pay the $20-$30 so I can say I paid for it.

But thanks for your input.

Ty thanks so much for providing us with this much easier method than what were previous instructions. Your method has worked without fail for me going back to the Previews. I can not recall off hand which Preview. I just wanted to take a moment to personally thank you for sharing this with all of us .....hats off to you bro .....

Sincerely,

Slide

You mean now or after the release to the public ? Why would anyone want the GM version over the actual public release in a few days ??


http://liondiskmaker.com

Maybe because the public release is the GM? :rolleyes: GM = Golden Master, the final build of software given to developers before the same build is released to the public. Barring any major show-stopping bugs found in the build, the GM is the EXACT same thing that will be released to the public. This has been the case for every iOS and OS X release that I can remember.

OK. I knew about the GM, but just thought, why not just wait for the release instead. Not long to wait, but that's just me. Just curious I guess. ;)

Edited: This might a reason to wait as well. https://forums.macrumors.com/threads/1656469/

For those who are not developers or prefer step-by-step instructions, here is how I made a bootable USB drive for the OS X Mavericks GM:

- Obtain a copy of OS X Mavericks GM from the usual sources (torrents, friend with a developer account, etc.)
- The file you download will likely be a .dmg with "Install OS X Mavericks.app" inside. Mount the .dmg and copy "Install OS X Mavericks.app" into your Applications folder.
- Attach an 8GB (or larger) USB flash drive, and open Disk Utility. Select your flash drive in the left column, and then click the "Erase" tab. Format the drive with Mac OS Extended (Journaled) with the name Untitled
- Click "Erase..."
- Close Disk Utility once the process completes. Open Terminal and enter the following command (you can copy/paste):



After you hit Enter, you may be prompted for your password. Type it (the cursor in the Terminal window will NOT move) and then hit Enter again. The process should begin.

- You should see something like this (note that this process can take 15-20 minutes to finish):

Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.

- You can now boot from the USB flash drive by holding the Option key while your computer boots up.

this is strange, followed the directions, it did what you wrote, but the drive did not work.
pressed ALT key on start. it shows the drive, starts to load, but then it just hangs on the spinning gear and eventually i get the circle with the slash in the middle.

this was done with GM maverick that was located on external dive - i just changed the path.

Then it's not strange. That's why it didn't work. Don't change the path. In fact don't change anything. Do it exactly as I said and it will work:

Others have added their own complications to it and have asked why it didn't work. Pretty obvious actually.

i downloaded the GM - it's on external drive.
do i just need to copy it to applications older ?
it makes no sense why path would affect this ?

if i move it to the Applications folder, it does not work at all.

If you very carefully look at the 2 pictures you put up, you will see that the command you put into terminal is looking for

Install OS X Mavericks.app

But your installer is called

OS X Mavericks.app

This is why it could not find the createinstallmedia executable file.

As I said in my original instructions, it should be called Install OS X Mavericks.app

There are 2 ways you can solve this problem.

1. Rename the installer Install OS X Mavericks.app

OR

2. Modify the command to

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

I have removed the Install bit of the name. It should find it now.

I just hope your USB is called Untitled!
 
1) put the "Mavericks.app" on the desktop
2) empty partitioned drive named "aaa"


* you can change the name or location, just make sure you change the path of the command below.

then execute this command:
Code:
sudo /Users/your_username/Desktop/Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/aaa/ --applicationpath /Users/your_username/Desktop/Mavericks.app --nointeraction
 
So did it work for you now?

yes, it worked fine.

* i noticed a glitch with the installer. if you have plugged in projector or display, but it's not turned-on, the installer will have wide inactive bar on top and you won't be able to click and proceed with the install.
 
I must be doing something wrong...can't get this to work, sorry I'm new at this kind of stuff keep getting command not found, changed what you said and still nothing. Guess I'll wait, until it comes out in the app store and go from there. Thanks

I have tried this example of making a USB Drive, however it gets stuck at one second remaining, and like in the other post i wait and it reboots, but then all i get is the startup screen, the gong played but then a white screen no logo, so i am assuming that this is the silent install? I have left it either way...

any help appreciated

Sometimes during installation it seems to hang. But it isn't really hanging. I and others have said that we get a message about a second remaining - half an hour later it finishes!

So you just have to patient. Leave it alone and it will eventually install.
