This is where UniBeast comes in, as a very simple to use tool for rapidly and quickly creating a bootable USB drive using the macOS copy you bought from the Mac App Store or downloaded for free if your Mac is running Mavericks or Yosemite. The resulting USB drive allows for a clean install, upgrade or use as a rescue boot drive.Ĭreating a bootable USB disk with a copy of macOS can come in very handy if you need to clean install the operating system on your Mac, if you want to upgrade it easier or if you require a rescue disk for getting back your data from a crashed hard drive.Įven though you can do this with the tools built-in within macOS, by combining the power of Apple’s Disk Utility and the Terminal, the process may be too complicated for some newer macOS users or just plain difficult if you’ve never used the Terminal before.Ĭreate bootable USB drives from any macOS installer downloaded from the Mac App Store This tool creates a bootable USB drive from your Mac App Store purchased copy of macOS. UniBeast has been updated to version 10.3.0 for macOS Catalina.
