Apple has seeded an OS X El Capitan Recovery Update for Mac that includes improvements to OS X Recovery. The software update can be installed through the Mac App Store and is recommended for all users running a pre-release version of OS X 10.11 El Capitan.
OS X Recovery is a feature on Mac that includes tools to reinstall OS X, repair your disk and restore from a Time Machine backup. The update supplements the seventh OS X El Capitan developer beta and fifth public beta released on Wednesday.
OS X El Capitan will be released in late 2015 as a free upgrade through the Mac App Store.
