Memory Cleaner
Memory Cleaner is a macOS utility from Nektony that monitors RAM use, frees inactive memory, and helps users manage memory-hungry apps.
What is Memory Cleaner?
Memory Cleaner is a native macOS utility designed to help users watch RAM usage and free inactive memory when their Mac feels slow or crowded. It is aimed at everyday Mac users who want a simple way to monitor memory pressure from the menu bar without opening several system tools. The app can show current memory usage, identify apps that consume large amounts of RAM, and run cleanup manually or automatically when available memory gets low. It also includes tools that help users close unresponsive apps and review basic disk-related cleanup information inside the same interface. For people who multitask heavily, work with many browser tabs, or use creative and office apps together, Memory Cleaner offers a lightweight way to keep an eye on memory behavior during normal Mac use.

- Monitor RAM usage in real time from the menu bar

Safety overview
Status: Mostly safe
Memory Cleaner is a legitimate Mac utility for monitoring memory use and freeing inactive RAM. Its system monitoring and cleanup behavior are normal for this kind of app, and some features may request additional macOS permissions to analyze storage or help with related cleanup tasks. Users should expect changes in available memory readings after cleanup, but it should not remove personal files as part of its core RAM management function. If you do not use memory-cleaning tools, removing the app simply takes away those features.
Recommendation: Keep Memory Cleaner if you use it to watch RAM usage or quickly free inactive memory while multitasking. If you no longer rely on it, you can remove it without affecting macOS itself, though you will lose its menu bar monitor, cleanup controls, and app management conveniences.
