Assuming you got Mavericks through the app store, you have an app called "Install OSX Mavericks.app" sitting in /Applications. Step 0 is to back the install app up since it likes to delete itself once the install is done. Step 0a is to make sure you aren't installing Mavericks on a "real" machine but rather on a test box. Now that those items are behind us, it turns out it's a little bit more tricky to make your own USB stick. In Lion and ML, all you had to do was restore InstallESD.dmg to a usb stick. In Mavericks, there are a few more steps... 1) Set finder to show hidden files 2) Pick the install app in finder and "show contents" 3) Navigate to InstallESD.dmg in (contents/sharedsupport) and (optionally) copy it out someplace for yourself to work on. 4) Mount InstallESD.dmg and look for basesystem.dmg (which is a hidden file and the reason for step 1 above) Restore basesystem.dmg to an 8GB USB stick. 5) Find a sym link (in /system/installation) to packages and replace it with the real packages folder copied from InstallESD.dmg. 6) (optional) Set finder to hide hidden files That's it. You now have a Mavericks DP1 install/recovery USB stick. I successfully installed Mavericks on a test machine using the USB stick I created using these instructions. Source: 9to5mac.com I really wish Apple would put everything you need to do a restore in the recovery partition(I really should find the time to go poke around in Maverick's recovery partition to see if the have already done this). I would still make myself a stick just in case a HDD crashed completely, but even if it didn't crash completely I don't want to sit through a restore from the Lion or ML recovery partition because so much has to come down over the internet. The up side is you don't need a software update afterwards. The down side is a recovery that could get done in 20 minutes can take a lot longer depending on the speed of your internet connection. I had posted this in another thread but as more developers and eventually users install 10.9, this needs its own thread.
