DiskMaker X Pro
DiskMaker X Pro is a macOS utility for building one bootable external installer disk that holds multiple versions of OS X and macOS.
What is DiskMaker X Pro?
DiskMaker X Pro is a macOS utility that helps users create a single bootable external disk containing multiple OS X and macOS installers. It is designed for Apple support work, repair workflows, lab environments, and anyone who needs to reinstall different macOS versions without downloading each installer again on every Mac. The app prepares an external drive, creates the needed partitions, and makes each included installer bootable. It also keeps remaining space available in a separate area so the drive can carry other tools and files. DiskMaker X Pro is especially useful for technicians and advanced users who maintain several Macs with different operating system requirements. The app is published by Guillaume Gete and focuses on faster reinstall and deployment tasks on Mac hardware.

Safety overview
Status: Use with caution
DiskMaker X Pro is a legitimate utility, but it works by preparing and erasing an external disk to build bootable installers. That behavior is normal for its purpose, yet it can permanently remove data from the selected drive if you choose the wrong disk. Use it only with a drive reserved for installer creation, and make sure any important files on that drive are backed up first.
Recommendation: Keep DiskMaker X Pro if you actively create multi-version macOS installer media or maintain several Macs. If you no longer use it, you can remove it, but make sure you do not confuse the app with any installer drive or files you still need for recovery work.
