Memory Clean is the ultimate app for optimizing your Mac's memory.

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

Version 4.5:
  • Please note: This version contains our optimized cleaning code that ensures the app works perfectly on all Macs.
  • Bug fix for crashing issue

I've a few memory optimizers but this is the best one and well worth the small price tag. Please disregard the drive by insult by someone who didn't have the decency to state what it was he/she didn't like.

A program like more...

I compared all the memory purge utilities, and found Memory Clean to have the best interface, the most robust features, and a clear graphical representation of memory usage supported by a list of different types of memory used. A lot of thought went into this app and it shows. It's one of those "I can't believe this is free" apps.

My only qualm is the menubar icon/text, which convey little info relative to the space occupied. iStat Menues has the best menubar memory icon/text design that I've tried, and it would be nice if Memory Clean were updated with something similar. A pie chart, and two lines of small font text showing used and free memory.

Four stars for now, to be updated to five stars if the menubar icon is fixed.

Arrrrggghhhhh! I rebooted and Memory Clean punk'd me with an advertisement!

If this happens again, ZERO STARS. I will not tolerate adware on my Mac.

Snake oil, my a**. Without the ability to run a quick purge without opening Terminal, I'd have to be restarting Safari way, way often. MacBook Pro, 8GB RAM, 10.9.2 ....and have been using Apple portables since some of you Superior Ones were in diapers. Instead of acting out here, go to Apple Feedback. It's Apple engineers who aren't fixing the hogs like Safari Web Process. Yeah, I want to use Safari, which is otherwise so fine ...

Whether one believes this is snake oil or not, it does not work as it once did. It used to clean the majority of my 32GBs when I would bother running it. Now it only cleans 4-5GBs at a time.

Question: since Mavericks handles memory allocation in a new way, how much good to programs like this actually do?

The more accurate question is: how much performance degradation will I see (answer: the same as previous versions of OS X). All modern operating systems use caches for a good reason, purging them has never been shown to do good (apart from the subjective reports of general users that seeing more green in their memory map makes them think things are somehow "better").

In my experience, using a similar application called "MemoryOptimizer", I am able to rectify an issue I encounter while running an audio equalizer application ("Boom"). If I am running a few applications and use Boom as well, I get a periodic (on average once every 15-30 seconds) clicking sound in the music I am listening to. Running MemoryOptimizer rectifies the problem each time. It has not once failed to correct this for me. Is this because my memory is being spread too thin? I haven't the slightest idea. I'm just glad it works.

Great little app...
Occasionally after prolonged computer use, I would run purge via terminal. I wanted something that I could just click in the GUI and be done. I tried a few of the other free and shareware memory scrubbers (lets face it, they don't optimize, they just release and defragment), but they had their limitation or complexities that kept me away.

This app has been relatively effective and simple to use. A simple click is all I need to clear the RAM and prep the computer for apps with high memory use.

Word of caution: repeated memory clearing (two or more attempts in a row) may yield a lot of free memory, but you will find that apps that are already running are a little sluggish at first and the start up of other apps will be a little slow as well.

However, once they are running for a few moments, the degraded performance go away. This is very evident in the Finder speed which is slow at first after clearing the memory, but then picks up speed back to normal.

A program like this becomes necessary when you fire up memory hogging apps like VMware Fussion, Safari, iMovie, Photoshop etc. which will literally take up most of the 8GB of RAM on my MacBook Pro. Simply closing out the app does not recover the RAM back. In fact, only 2GB of memory is free when originally I had 5GB free before using these apps. Constant rebooting is just not convenient.

You are being misleading/misled and/or don't understand how virtual memory works. Many technical computer users consider memory optimisers snakeoil and have for years. Read first about virtual memory. Then read some articles about why purging "inactive" RAM is useless and harmful to computer performance. This is a beginners guide and targets the Linux VM but OS X's VM (and VMs in general) is conceptually equivalent:

http://www.linuxatemyram.com

This is a great article from Sysinternals guru when this sort of junkware was all the rage on Windows:

http://www.windowsitpro.com/article/internals-and-architecture/the-memory-optimization-hoax

or

http://www.howtogeek.com/171424/why-memory-optimizers-and-ram-boosters-are-worse-than-useless/

Rephrased for OS X users:

http://reviews.cnet.com/8301-13727_7-57589907-263/the-necessity-of-regular-use-of-the-purge-command-in-os-x/

And if you prefer a bit more meat to the bone:

https://developer.apple.com/library/mac/documentation/Performance/Conceptual/ManagingMemory/Articles/AboutMemory.html

Again, if it makes you feel better to see all that green "free" RAM then good for you, but thinking this is necessary ignores the technical reality of this kind of software...

Totally agree. OS X Mavericks or Mountain Lion IMO are horrible at managing memory…especially inactive RAM. Memory Clean is the best one I have used, including Free Memory Pro. I use it on my iMac (24 GB RAM) and MBP )16 GB).
