Install Disk Creator
Install Disk Creator is a macOS utility that creates bootable USB installers for macOS, helping users reinstall or deploy macOS more easily.
What is Install Disk Creator?
Install Disk Creator is a native Mac utility for creating bootable macOS installer drives from a USB stick or other external media. It is designed for people who reinstall macOS, prepare recovery media, set up multiple Macs, or keep an installer ready for troubleshooting. The app provides a simpler alternative to manual Terminal steps by guiding you through choosing a macOS installer and selecting the target drive. Current versions also support downloading official macOS installers directly, which is helpful for users who do not already have the installer app saved locally. Install Disk Creator is published by Ben Slaney through MacDaddy and is intended for macOS workflows on both Apple silicon and Intel Macs. It is best suited to maintenance, recovery, lab deployment, and clean-install preparation.

Safety overview
Status: Mostly safe
This app is used to erase and prepare external drives so they can become bootable macOS installers. That behavior is normal for its purpose, but it means selecting the wrong target drive could remove data from that drive. Use it only with removable media you intend to repurpose, and double-check the selected disk before starting.
Recommendation: Keep Install Disk Creator if you create macOS installer USB drives, maintain multiple Macs, or want recovery media ready when needed. If you no longer use it, removing the app is usually fine; just remember that any installer drives you made separately will not be updated by the app afterward.
