First Launch & Using the App:
The app functions as a menubar app. This means that as soon as you download the app from the Mac App Store and launch it, it’ll appear in the top menubar on your Mac’s screen as a small meter icon.
Upon first launch, the app will appear on your menubar with a small meter icon and a numerical value of the amount of free MB you have on your Mac. If you click this on your menubar, you will notice the app window appear with a more detailed view and a colour coordinated and pictorial representation of the same data.
Under the main ‘Free Memory Available’ section and corresponding coloured graph, you will notice a ‘?’ (question mark) icon. Clicking on this will provide you with an explanation for each of the corresponding stats displayed within the app.
Hit the ‘Clean Memory’ button at the bottom of the app to purge the Mac's inactive memory. This is best used when you close an intensive program that you do not plan to use again quickly within a few hours.
Memory Clean frees a safe amount of Memory from your Mac. If you run the cleaning process again straight after freeing memory, you will be able to release more memory, but we only recommend this to users who know what they are doing as cleaning memory too often in a short amount of time could cause your Mac to freeze up.
You can right-click the menubar icon for Memory Clean (or hit Cmd + , keys together with the app window open) to launch the Preferences menu. Please see the image below to view the list of customizable options present in the Preferences panel.
General: This allows you to select whether you want to launch the app at login, have the app appear in the dock, edit text size, display percentage/numerical figures and more.
Advanced: Allows you to set a threshold level for which the icon (and corresponding text) in your menubar will turn red should the free memory level fall below that. You can then choose to specify the app to run an ‘Auto Clean’ function with a specified refresh interval for checking on the memory levels.
