: Usually distributed as a .dmg or .iso file, often pre-configured to be bootable without requiring the standard "createinstallmedia" Terminal commands.

I'm not familiar with a specific "Webdude Repack" of OS X Mavericks 10.9. If you're referring to a specific third-party repackaging of the installer, please provide more information about it.

sudo installer -pkg /Volumes/OS\ X\ Mavericks\ 10.9/Install.app/Contents/Resources/Install.pkg -target /Volumes/YourUSBDrive

Q: Can I use this bootable install ISO on multiple Macs? A: Yes, you can use this bootable install ISO on multiple Macs, as long as they are compatible with OS X Mavericks 10.9.
