anyone have directions on how to turn the mavericks installer into a usb install drive? I want to do a clean install and that seems to be the best way.
it looks like apple has changed the installer files so that previous methods no longer work.
The quickest way I do is as follows: After getting the redemption code, start to download the DP from the App Store. It starts to download the DP install file to the Applications folder.
Once the download completes you will be greeted with the install screen. DO NOT proceed! Because once you initiate the install, the file will be automatically deleted from the Application folder and for subsequent installs you will have to download it again.
Copy the "OS X 10.9 Developer Preview" file from the Applications folder to a different drive before initiating the install. It could be a second attached drive or a USB drive. It is 4.97Gb in size.
Now you have 3 choices:
1) Continue with the install by clicking continue. The install file will be deleted from the Applications folder, but you already saved a copy.
2) Make a bootable USB stick using the copied install file. The method is the same as any other previous issues of the OS X from Lion onward, involving the extraction on the InstallESD.dmg file from the package and copying to an external bootable drive. Apple hasn't changed the install file to my knowledge.
3) Use this copied install file to install 10.9 on any other machine in your control. As long as the install file resides in another drive from the one you are installing, it will not be deleted upon completion of the install.
I prefer method 3 as I have multiple machines to test using different configurations.
