If you need to create a bootable USB drive for your Mac OS X platform to try and recover or manage data — Disk Drill is the number one choice on the market.
MacOS hasn't shipped as a bootable disk for a number of years now. While more and more software solutions are moving to download-only, there are times when you need a physical copy. It's especially inconvenient when you need a running Mac to access the Mac store in order to download macOS. What do you do if your Mac crashed and becomes unbootable? That's when you might need a bootable USB drive. It makes fixing or reformatting your faulty system much, much easier.
Disk Drill's bootable drive facility will also help recover lost or hidden data on your Mac before you reinstall the OS. This is especially useful as most reinstallation techniques will lose important files as your system needs to be reformatted to work properly again.
