Optimize

Inspect supported login and background items, understand their owners, and change startup behavior safely.

Distinguish login apps, background helpers, launch agents, and supported services before changing startup behavior.

Test a startup change, preserve the owning application, and restore functionality if a required helper stops running.

Interpret used memory, cache, swap, and sustained pressure before choosing a supported memory action.

Adjust interface effects one at a time and restore defaults when a change does not improve your experience.

Manage startup items, memory, visual effects, metadata, and sensitive files.

Answers about startup items, memory, visual settings, authorization, and reversible testing.

Avoid repeated cache deletion, forced free-memory targets, and disabling every background item.

Recheck startup items, visual settings, permissions, and temporary workload after a system update.
