TechTool Pro 13
TechTool Pro 13 is a Mac utility for hardware diagnostics, drive testing, repair tasks, and maintenance checks on supported Macs.
What is TechTool Pro 13?
TechTool Pro 13 is a Mac utility focused on diagnosing hardware, testing storage, and performing maintenance tasks on supported Macs. It is designed for users who want a deeper view of system health than the built-in tools typically provide, including checks for memory, sensors, batteries, volumes, and other hardware-related components. Common uses include troubleshooting crashes, checking drive condition, scanning for file structure problems, and running broader health tests before or after repairs. The app also includes tools for maintenance and data-related workflows such as cloning and drive-focused service tasks. On modern versions of macOS, some functions require security permissions such as Full Disk Access so the app can inspect disks and carry out repair or maintenance operations. TechTool Pro is published by Micromat, Inc. and is part of a long-running line of Mac diagnostic and repair software.

Safety overview
Status: Mostly safe
This is a legitimate Mac maintenance utility. Some features may request elevated access, including Full Disk Access, because disk testing, cloning, and repair functions need broad visibility into storage. That level of access is normal for this type of tool, but you should grant it only if you use those features and make sure important data is backed up before running repair or maintenance operations.
Recommendation: Keep TechTool Pro 13 if you use it for diagnostics, drive checks, or maintenance on your Mac. If you no longer use these tools, removing it is usually fine and mainly means you will lose its testing, repair, and monitoring features until you reinstall it.
