Mac performance optimization software (research shortlist)

CleanMyMac X: All-in-one cleanup and maintenance suite for finding junk files, uninstalling apps, and running some basic performance and security checks.

OnyX: Power-user maintenance tool for running system scripts, clearing caches, and changing hidden settings. Use carefully.

DaisyDisk: Disk space visualizer to quickly find and remove large files that may be clogging storage.

iStat Menus: System monitoring to spot what is using CPU, memory, disk, or network in real time.

Malwarebytes: Malware and adware scanning and removal.

Notes: For performance, the biggest wins are usually freeing disk space, reducing login items, and identifying runaway processes. Monitoring tools help diagnose; cleanup tools help execute.
