Drive Genius is a discontinued macOS utility application developed by ProSoft Engineering that was designed to maintain and optimize hard drives and solid-state drives (SSDs). It offered a range of features including :

*

Disk Repair:

This was a core function, aiming to identify and repair various drive issues, potentially preventing data loss.
*

Drive Optimization:

It included features to improve drive performance, such as defragmentation (more relevant for HDDs than SSDs) and other optimization routines.
*

Data Recovery:

Drive Genius offered basic data recovery capabilities to help retrieve lost files.
*

Monitoring and Diagnostics:

It provided tools to monitor drive health, temperature, and performance characteristics.
*

Backup and Cloning:

Some versions incorporated tools to create backups and clones of hard drives.

Important Note:

Drive Genius is no longer actively developed or supported by ProSoft Engineering. While older versions might still function on some macOS systems, using outdated software carries risks, including incompatibility issues and lack of security updates. Apple[SQ]s built-in Disk Utility, combined with Time Machine for backups, generally provides adequate functionality for most users. For more advanced needs, other current and actively supported alternatives are readily available.
