Memory Clean is a menu bar app for macOS that optimizes your Mac's memory (RAM). It is especially useful after closing memory-intensive apps or games, giving your system the feel of a fresh restart.

Getting Started

Memory Clean runs entirely from the menu bar. After downloading and launching the app from the Mac App Store, a small meter icon will appear in the top menu bar of your screen.

The menu bar icon displays the amount of free memory available on your Mac as a numerical value. Clicking the icon opens a detailed window with a color-coded graph showing a full breakdown of your memory usage.

Below the main Free Memory Available section and its graph, there is a question mark icon. Click it to see an explanation of each memory statistic displayed in the app.

Cleaning Memory

Click the Clean Memory button at the bottom of the app window to purge inactive memory from your Mac. This works best after you have closed a resource-heavy application that you do not plan to reopen soon.

Memory Clean frees a safe amount of memory by default. Running the cleaning process multiple times in quick succession can release additional memory, but doing so too frequently may cause your Mac to become temporarily unresponsive. Only repeat cleans in short intervals if you are comfortable managing your system's resources.

Settings

To open the Settings panel, right-click the Memory Clean menu bar icon or press Cmd + , while the app window is open.

General -- Configure options such as launching the app at login, showing or hiding the Dock icon, adjusting text size, and switching between percentage and numerical memory readouts.

Advanced -- Set a threshold for free memory. When available memory falls below this level, the menu bar icon and text will turn red. You can also enable Auto Clean, which automatically cleans memory when it drops below the threshold, and set a refresh interval for how often the app checks memory levels.
