Disk Creator Mac Os El Capitan
'sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X El Capitan.app --nointeraction,' That's the command that was required to create an OS X install disk up until the debut of Install Disk Creator. Creating an OS X El Capitan installation disk was formerly a complicated, arcane process. MacDaddy's Install Disk Creator simplifies the process, reducing the process to simply downloading the OS X installer from the Mac App Store, running the Install Disk Creator app, and selecting the drive to create the installation disk on.
'Creating an OS X Installation disk on a portable drive, such as a USB stick, has always required jumping through hoops,' shared MacDaddy CEO Ben Slaney. 'Most Mac users don't have the knowledge or patience to enter the complicated commands that are required to create an OS X installation disk. That's where Install Disk Creator 1.0 comes in. It reduces the process to simply downloading our app from the MacDaddy website, and the OS X installation files from the Mac App Store. plugging-in an 8GB or larger USB Stick, and running our app. In a short time, they'll have an installation disk they can use to install OS X 10.11 El Capitan on any compatible Mac.'
Install Disk Creator is an easy to use application, that presents a clean and simply designed interface that can guide any user through the process of creating a Mac OS X installation disk. Novice users will appreciate the application's ease of use, while power users will appreciate the ability to create installation disks without the need to remember the entire series of commands that were once required to create an installation disk. All users will appreciate the convenience of having created a USB installation disk that they can use any time to install OS X on any compatible Mac.
Using Install Disk Creator to create an OS X installation disk is the only way to do a truly clean installation of OS X. While users can boot from the recovery partition to erase the main partition, it isn't a truly clean erase and install. And, in some cases the recovery partition may be damaged or missing. Install Disk Creator helps users avoid those issues.
'Many users like to install the new version of OS X as a fresh install,' continues Slaney. 'However, the way Apple now distributes new versions of OS X via the Mac App Store makes it difficult to do a fresh install without requiring the user to jump through a number of hoops. Install Disk Creator simplifies the process, making it easy for any user to create an installation USB stick, and use it to install OS X El Capitan on their Mac.'
