MacDaddy has rolled out Install Disk Creator 1.0, a new installer disk utility for Mac OS X. It’s designed to simplify the process of creating a bootable OS X installer from Mac App Store installation files.
Before you could only do this by using the Terminal app. However, Install Disk Creator makes the process of creating a bootable Mac OS X 10.11 El Capitan install disk simple enough for any experience level user to perform, says MacDaddy CEO Ben Slaney.
Install Disk Creator requires Mac OS X 10.7 or higher. It’s free; more info can be found here (http://tinyurl.com/nmeavdo).
