Memory Cleaner
Memory Cleaner is a macOS utility from Nektony that monitors RAM usage, frees inactive memory, and shows disk usage details from the menu bar.
What is Memory Cleaner?
Memory Cleaner is a native macOS utility that helps users watch memory usage and free inactive RAM when their Mac feels sluggish. It is designed for people who want a simple menu bar tool for checking available memory, seeing which apps use the most RAM, and running manual or automatic cleanup. The app can also force quit frozen apps and display disk usage information, including categories such as junk files, duplicates, large files, and old files. For users who want broader cleanup workflows, it can connect with tools in the MacCleaner Pro family. Memory Cleaner is published by Nektony LLC and is focused on everyday Mac maintenance rather than general-purpose file management or productivity work.

Safety overview
Status: Mostly safe
Memory Cleaner is a notarized Mac utility from Nektony that performs functions consistent with its purpose, including RAM monitoring and optional disk analysis. If you use its disk usage features, granting Full Disk Access is expected so it can scan files across your Mac; review that permission carefully because it allows broad visibility into user data. Automatic cleanup and menu bar presence are normal for this kind of utility. Use the app only if you want active memory monitoring or cleanup features, and download it from Nektony directly.
Recommendation: Keep Memory Cleaner if you actively use its menu bar memory monitor, automatic cleanup, or force-quit tools. If you do not use RAM cleaning utilities or prefer relying on built-in macOS tools such as Activity Monitor, removing it should mainly affect those convenience features and its disk usage views.
