The GM versions are the same as the public release. So to answer your question, yes, you can update from the GM version of Mavericks later releases.

Thank you so much! I just wanted to be sure I wasn't going to make an install drive with a version of OSX that couldn't update haha
 
What are the "best" instructions for making a bootable USB of the GM? And I echo the above comment, wondering what the correct checksum of the file is :)
 
Very simple. Mac format the pen drive, (GUID map, Mac OS file system) open the dmg, click the dmg in disk utility, click restore tab, drag newly formatted usb drive partition (not the drive itself, the partition) into "Destination", press restore, enter password, wait for it to finish, you're done.

If you are not a developer and want to make a bootable USB drive for the OS X Mavericks GM, follow these instructions:

- 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):

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

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 worked perfectly for me and I hope it helps some of you!

I bought the new MacBook Air that just came out. Around weeks after it released. Will i qualify for the free OS X Mavericks Upgrade?

How many weeks? In the past it's been free for those who bought a mac a few months before the release date.
 
I am no expert in this field, nor do I pretend to be. All Im trying to say is that I would be very cautious with the software I trust my computer with. It is however technically possible to create a checksum collision, how feasible this would be in this case is beyond my expertise.

Creating a checksum collision seems like an pretty far extreme for someone to go to.
 
Hi everyone... Am unable to upgrade from ML to Mavericks GM, so clean install (via bootable USB drive) is the only way to go for now. Is there a way to still have the recovery partition in place when doing so?
 
As an aside, I'd be cautious upgrading the OS to 10.9 GM without applying the iPhoto update as well. A similar requirement bit me with 10.7 GM, corrupting my iPhoto library quite badly. Back then, I wasn't using Time Machine (I know... :rolleyes: ) and it was a real pain to recover.

I updated to the GM first then applied the iPhoto update and have no issues.

But updating iPhoto first would probably be better.

When Mountain Lion came out there was an "Up to Date" program from Apple that gave it to you free if you bought a Mac within six weeks of the release. This program was announced before the release of Mountain Lion. The fact no program like this has been announced yet for Mavericks has caused some to speculate Mavericks will be free. We will just have to wait and see I guess.

Very Nice & Thanks

Took me about 8 minutes to make the drive (Patriot RAGE 8gb) The install was interesting. I used a clone on a WD Edge to test until I'm ready to commit on the iMac. Bet it's much slower than what I'll experience on the iMac's internal flash drive.

For Reference - Initial install progress was 7 minutes, and as some have noted, when it gets to 1 minute remaining, it's really 8 more minutes. After the restart, it was 28 total, including 1 minute remaining being actually 6 ;)

Again, the terminal command worked just fine here.
 
Got Mavericks installed and works ok on my MBA but i have one concern. It seems the maps sending to Iphone with IOS7 installed is not working, I already logout/login on both icloud and location service is enable but still not working. Anybody have idea if i miss something on setting on both device. Thanks
 
I have read that clean install requires apple ID with purchased Mavericks or a developer account, is that true?
also I read that some people say there are workarounds for that, so what are the workarounds ?

Hm. That'd be weird. I know they didn't require that for a Lion clean install via flash drive. And I think if so another poster would have mentioned it when saying the install was successful.

No, if you are doing a clean install from a USB installer there is no verification required via Apple ID or dev account.

The only time the system will verify if you have purchased Mavericks is if you attempt an internet recovery install.

I performed a clean install last night and it did not ask me for my Apple ID to install. It only asks for it after the installation is complete and you are setting up iCloud/iTunes. Again, I do not have a developer account.

If you are restoring in the future through the recovery HD, yes, you will need to enter your Apple ID to download the installer.

If you illegally obtained the GM, you will not be able to download the installer.
