AWARDED MACWORLD 'MAC GEM' 2013 - The Best Memory Cleaning App

Memory Clean is the ultimate app for optimizing your Mac's memory and is best used after you have finished using a memory (RAM) intensive app or game.

With the slickest interface and user experience, Memory Clean stands head and shoulders above the rest.

Note: Memory Clean works by purging the Mac's inactive memory and is best used when you close an intensive app that you do not plan to use again quickly within a few hours. During the cleaning process, older Macs may slow down until the cleaning is complete.

What's New in Version 5.8

This update adds the ability to hide the 'Unlock Extreme' button on the user interface. Thanks for your feedback - we do listen. Be sure to check out our new free alarm clock app, search for 'Timeless' on the Mac App Store.

We hope you are enjoying the free themes we added in the last update! Please email us with suggestions for more theme colours and new features :)


Message to OS X 10.10.3+ Users - Please note that Apple has updated the way Used Memory is calculated and that's why we no longer include 'File Cache' in Total Used Memory figure. If you compare with Activity Monitor, you will see that the Used Memory figure in Memory Clean matches up with what is reported on Activity Monitor. File Cache will STILL be cleaned by Memory Clean.


Memory Clean now has more than 4 Million downloads! We'd like to thank all our loyal users for supporting us for nearly 4 years! Memory Clean has won multiple awards during that time, including the MacWorld 'Mac Gem' and 'Invaluable Utility App' from Apple.

Geritol for aging Macs

It’s become obvious to me that building computers is like building Intertstate highways. The more memory you build into Mac or lanes of roadway you construct, the users (or software developers) will find ways to use ALL the capacity provided. And so we are faced with traffic, slowdowns and dreaded spinning beachballs. I used to use DiskDoubler and RamDoubler in the old OS 7 - OS 9 days, along with file compression routines involving Stuffit and other tools. In recent years I have been able to live a fairly carefree life with OS X, and its ability to manage memory, defragment my drives for me, largely monitor my computer realm for virus attacks. But things seem to be getting way more complicated in the back room of my Mac these days, and I’m not being told very much about it, even having been some sort of a “power user” over the years. All I know is that there are lots of slowdowns, almost every day, while I am trying to switch tasks, launch apps and quit others. The MemoryClean menu bar indicator is great in letting me know when my RAM is “pinching” and helps me right the ship by pointing out the worst app offenders so I can quit them. AND, MemoryClean has finally put before my own eyes a very persuasive argument for why I should finally invest in the additional RAM upgrade from 4 to 8 GB, which will make memory pinching less routine of a problem, and more of an exception. Not forever . . . but for now!

Time spent defering offers and ignoring rating request is intolerable

Any boost provided by clean memory is ruined by the time I spend declining request to rate (keep rating, I guess) the app, declining offers of new products, and having to update the product. There is no possible justification for all of the app updates for reasons of new code—I suspect (could be wrong) that it has to do with more offers that I have to decline. In any case, whatever productivity I might gain by cleaning my memory is offset by the time I spend dealing with the constant instrusions.

I did discover that by denying it outgoing communcication some of the irritation was reduced. Then it occurred to me that I’m having to fight this app. What in the world would make me desire such an outcome? Not some good feeling that my memory is “clean.” OSX is a powerful operating system that manages memory admirably, if not perfectly. Having used Apple OS’s since 1985, I am delighted with it. But many of us are incessant tweakers, and always attracted by free utlities. I’m one of those. But even I have a limit.

This app is no longer on my system. Whatever good it offers is negated by very poor choices on the part of the producers. Were they to leave the user alone other than offering an worthy paid upgrade, it might actually be a good product. As it is it is an example of either greed or incompetence.

Awesome product for older macs!

I would like to start by saying this app is wonderful! I have installed this on my MacBook air early 2008. Yes you read that right early 2008! This app really helps my MacBook air since she only came with 2 GB of memory and running 10.7.5 (Lion) which does use a ton of memory. This MacBook is a bit older yes but it still runs fast and this app really does help this computer retain its speed. Is it as fast as a new MacBook pro? No but I dont expect it to be. Another thing I really like about this app is that it shows you how much free ram you have in megabytes or gigabytes and it also gives you the option to change it to percentage. I ending up buying this app even though I knew buying it wouldn't help me much I just really wanted to show my support to the people who made this app. Thankyou guys for making such a reliable app that works great with older machines I honestly do appreciate it!
