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%.

But yesterday, I found the actual installation a rather tortuous process on my 2010 mbp (with hard drive). It went a lot smoother on my 2011 mba (with a ssd).

But in both cases, it got to 'Less than a minute to go' at the end and then it seemed to hang there for ages. It wasn't actually hanging. I waited it out and it did eventually finish. But this is just something to be aware of before you install the GM in case you think it isn't working at the end. Others have commented that they had the same issue.

It's not a big problem though. Just don't get impatient.

Click to expand.Well both by mbp and mba have 2 partitions. On the mbp, I had mountain lion 10.8.5 and mavericks DP8 which I upgraded to GM with the USB installer. You just have to be careful to select the correct partition. I chose not to do a clean install, so all my files were still there after the upgrade. Then I did it on my mba which had Lion 10.7.5 and mavericks DP8 which I upgraded to GM - again be careful to select the correct partition. Again all my files were still there afterwords. On the other hand, if you want a clean install you can use Disk Utility on the USB to format partitions first before installing.

Some people prefer that (and I might do it later at some stage, but I don't have time to install everything again at the moment - so I'll make do with the upgrades for now). 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). Click to expand.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%. Copying installer files to disk.

Copy complete. Making disk bootable.

Copying boot files. Copy complete. 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!

It's not a big problem though. Just don't get impatient. Why not? Did you wait long enough for the process to finish? It took me 20 min. Is your USB called Untitled?

Is it at least 8 GB? Is it formatted as Mac OS Extended (Journaled)? Is your installer file called Install OS X Mavericks.app and is it in the Applications folder? Did you type the command correctly (might be safer to copy and paste instead - I'm not being rude, but I don't trust my own typing either - I also copy and pasted it when I did it yesterday)?
