The term “Webdude repack” refers to an unofficial, pre-assembled bootable ISO image of OS X Mavericks created by an individual or group using the pseudonym “Webdude.” Unlike the official OS X Mavericks installer obtained from the Mac App Store—which typically comes as an .app bundle intended to run from within an existing macOS installation—a repackaged ISO is designed to be burned to a DVD or written to a USB drive as a standalone bootable volume. osx mavericks 109 bootable install iso webdude repack
