Memory Cleaner
Memory Cleaner is a Nektony utility for monitoring RAM usage, freeing inactive memory, and offering quick Mac performance tools from the menu bar.
What is Memory Cleaner?
Memory Cleaner is a macOS utility published by Nektony LLC that focuses on showing current memory usage and letting users trigger RAM cleanup from a menu bar interface. It is commonly installed as a standalone free utility and is also connected with Nektony’s broader MacCleaner Pro ecosystem. The app can display overall memory use, identify applications consuming large amounts of RAM, and offer automatic cleanup options based on configurable conditions. Nektony’s support materials also describe extra functions such as force quitting stuck apps and showing disk and junk-file statistics when the app is granted the needed macOS permissions. Users typically encounter it when troubleshooting slowdowns, high memory pressure, or frozen applications on a Mac. Because its deeper storage analysis features may request Full Disk Access, it should be treated as a legitimate utility that still deserves normal privacy review before broad permissions are approved.

Safety overview
Status: Mostly safe
This appears to be a legitimate Nektony utility, not a known macOS system component. It is generally safe when downloaded from Nektony, but some features may request Full Disk Access to analyze storage and junk files, so users should review permissions and only keep it if they trust and use its functions.
Recommendation: Keep it if you actively use its menu bar memory monitor or cleanup tools. If you do not use Mac optimization utilities, it is usually optional and can be removed without affecting core macOS features.
