Memory Clean 3 is an absolutely gorgeous, extremely powerful and super slick app for optimizing your Mac's memory. It's best used after you have finished using a memory (RAM) intensive app or game.

With its easy to understand interface and powerful feature set, Memory Clean 3 stands head and shoulders above the rest. This latest version brings with it brand new features such as:

Memory Clean 3 lets you know which apps are using up the most memory on your Mac and can automatically recover memory when you close them.

You can enable Memory Clean 3 to notify you when an app hasn’t been used for a period of time, such as 30 minutes. You can close these apps to reduce memory usage.

Customise your Memory Clean 3 interface with a choice of a beautiful light and stunning dark theme. You can also choose between a detailed and compact interface. Finally, the ever popular docked mode from the original Memory Clean is back!

Our users have experienced a smoother and faster experience after running Memory Clean 3. Memory Clean 3 is the successor to the award winning Memory Clean 1 and 2 apps that achieved several million downloads and were featured by Apple as an 'Invaluable Utility' on the Mac App Store.

Note: Memory Clean 3 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.

Slow iMac 27” 2.7GHz Intel Core i5 22 GB DDR3

I really like my big screen iMac 27” from mid 2011. I have poor vision so the large screen allows me to see small text. But my iMac has progressively slowed down to the point where I stopped using it, because it takes a long time to just start executing a command. I tried everything to speed up my iMac to where it was when I had first purchased it in late 2012. I increased my RAM from 6 GB to 22 GB, I deleted my travel photos and freed up my hard disk memory to 885 GB available (it is a 1 TB hard drive). I have been using memory clean for about 3 years and I recently purchased the updated Memory Clean 3. I cannot say that I notice an improvement. Memory Clean 3 seem to work about the same as the free Memory Clean original version I had been using. My iMac is usable now but still slow. But I like watching David Lean’s Lawrence of Arabia on a big iMac 27” screen.


An incredible problem solver

I’ve used the previous iterations of this product and now am using Version 3. It simply keeps wasted RAM to a minimum and therefore keeps my Macs running at top speed. Years ago I did a project using a Mac to run a display in a museum. The Mac ran 24/7. The software we were using had a memory leak that consumed RAM and eventually crashed the Mac every few days. In the end we had to program the Mac to shutdown and restart at 3AM everynight to clear the RAM. This solved the proablem… the hard way. I’m convicted this software would have been effective for clearing the RAM which would have saved me thousands of dollars in travel and troubleshooting time! Your mileage may vary but I love this app!!


A MUST HAVE! Works Perfectly

I love this app and I’ve been using it now for several years. I’m a graphic designer and videographer so RAM space is always a struggle when I’m working on a project(s). The app allows me to monitor my RAM usage while I’m working on my MAC. It lets me know what percentage of my RAM and computer is being used by what programs as well as providing a CLEAN or EXTREME CLEAN up for my memory. One of the features I appreciate also is a reminder of what applications or programs that are running and have not been used which can free up more space. This app is a gem!
