Chameleon SSD Optimizer
Chameleon SSD Optimizer is a free disk utility for macOS designed for users with SSD (solid state drive) storage who want to optimize system settings and drive performance. The primary feature is enabling TRIM support for third-party SSDs, which helps prevent performance degradation over time. Additional features include displaying SMART drive health data, repairing disk permissions, disabling the hibernation sleep image to reclaim space, tuning power-saving modes, disabling the Sudden Motion Sensor, and limiting file access metadata logging. The tool is intended for experienced users comfortable making low-level system changes via a graphical interface.

1 suggestionChameleon SSD Optimizer has not been updated since late 2012 and there is no evidence of a native Apple Silicon build. The app continues to run under Rosetta 2 today, but Apple is removing Rosetta in macOS 28 (September 2028), so this tool will stop working entirely on that release. Modern versions of macOS (Big Sur and later) have significantly improved native SSD handling and TRIM support, reducing or eliminating the need for third-party optimisation. If you depend on a specific feature this app provides — particularly enabling TRIM on third-party SSDs — check Apple's current documentation or explore alternative tools like DriveMon or Disk Diag, which offer native Apple Silicon builds and continued active development. For most users, however, the best path forward is to rely on macOS's built-in SSD optimisation and avoid third-party system-level tweaks that risk stability issues on modern hardware.
