Recovery Disk Assistant
Recovery Disk Assistant is an Apple utility for creating an external OS X Recovery drive that can help reinstall macOS and repair a Mac.
What is Recovery Disk Assistant?
Recovery Disk Assistant is a macOS utility from Apple that helps users create an external OS X Recovery drive on a USB device. It was designed for Macs running OS X Lion or Mountain Lion that already have an existing Recovery HD. The external recovery drive provides the same main recovery tools as the built-in recovery system, including reinstalling OS X, repairing disks with Disk Utility, restoring from a Time Machine backup, and using Safari from recovery mode. This makes it useful when you want a separate recovery option for troubleshooting or servicing an older Mac. It is a focused maintenance tool rather than an everyday productivity app, and most users only open it when preparing recovery media for emergencies or repairs.
Key features
- Create an external OS X Recovery drive on a USB disk or thumb drive
- Reinstall OS X from the recovery environment

Safety overview
Status: Safe
This is an Apple utility intended for system recovery tasks on older versions of OS X. Its access to disks and external drives is normal for its purpose, but using it will modify the selected external drive to create recovery media. Choose the correct drive before proceeding so you do not overwrite storage you still need.
Recommendation: Keep Recovery Disk Assistant if you maintain or troubleshoot older Macs that use OS X Lion or Mountain Lion, or if you want a dedicated external recovery option. If you do not use older Mac recovery workflows, you can remove it without affecting normal day-to-day use on a current Mac.
