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 5.6

We have listened to the feedback of our loyal users and have decided to make Memory Clean themes available to everyone for free in this update! Be sure to update quickly and start making use of them! Please email us with suggestions for more theme colours :)


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.

Please kindly help support the development of Memory Clean by leaving us an updated review!

Must-have app!

This is genuinely one of my favorite apps that I use on all of my Macs. I would recommend it to anyone to try out! I gladly paid for the pro features to support the creators. :)

My favorite part about this app over other memory cleaners (besides that now you can see the icons of the apps that use the most memory! THAT IS AMAZINGGG THANK YOU! AND EXTREME CLEAN IS SO GOOD), is that it has so many options for how you can view it on your machine. Want only an icon in your taskbar? Cool. Want text? We got different ways to show you that too! Only want to see your dock? That’s pretty sweet, we can work with that. And now THEMES! The posibilities are endless. :D Thank you for giving us these options!

What I would love to see in the future are more icons for the taskbar, and maybe an option to change the text more? Change the font and size posibly? It would also be really cool to see more themes, or an option to make your own (kind of like Alfred did in their releases)!

Thank you for all of your hard work! I can’t wait to see what you guys do next. I’ve already gotten several of your other apps that I enjoy as well (Can’t live without CopyClip)!

Undeniably invaluable

I might’ve had my gripes with the earlier versions of this app, but after the free upgrade with more capacity to free up more memory, this has become the Number 1 app I have recourse to. Upon a single click, I’ve got memory to sustain me throughout the whole day without needing to free up more memory throughout the day. The fact that it’s free is more than incentive to download this app. Really, having an older model Mac with only 2GB of memory doesn’t matter anymore now that I’ve got this app. No more system crashes, and no periodic waiting for more than just a few moments. This honestly is an invaluable app and its resourcefulness is undeniable.

Now a "Must Install" app for every system I encounter

Behind 1Password and Quicksilver (or your own preferred launcher), I'll be making sure Memory Clean is everywhere I am on a mac.

Whether you have 4gb on a 8yo Macbook Pro or 24gb like my 2012 iMac, it's phenominal! Know this: Your Mac will use ALL ram available to it, even for just surfing and email. This app fixes that for you in a big way. It's great on my old MBP, where resources are limited and unable to be upgraded, and it routinely finds me 10+gb of ram to put back into circulation as caches and whatnot eat up resources.

It's free, and invaluable. Just get it, and use it. You won't regret it.

(And if you do not want ot update with every decimal release, just ignore the updates... Personally, I'm happy to know that it's not abandonware, as so many other freeware apps become.)
