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

Fully updated for OS X El Capitan. We’ve worked super hard to optimize our memory cleaning algorithm and Memory Clean now frees up 50% more memory than similar apps. Extreme Clean often frees up more than 100% compared to others!

Please do leave us an updated review for version 6 of Memory Clean! Each and every review counts.

We’d like to thank everyone for their feedback and suggestions over the last year. We are aware that there have been frequent updates to this app as we have focused on continuously optimizing the cleaning logic. We are now very happy with the result and you will be glad to know that we will be moving to a less frequent update schedule from now on :)


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!
