A Very Helpful Utility

I did not feel the need to know how much of my RAM was active or free until I installed Yosemite on my 2007 iMac. Up until then, the iMac’s 3GB of RAM kept things humming even with many open apps. But with Yosemite I was watching spinning rainbows for what seemed like hours even when keeping open apps to a minimum.

This app not only enabled me to see how fully occupied my RAM was, its handy “clean memory” button enabled me to keep my iMac up and running until my new RAM arrived. I plan to keep it open (it shows in the memory bar) even with my now 6GB of RAM, just to see how things are running.

VERY happy with this app.


Seems to work well, automatically restores available RAM in background, whenever it gets “too low”...without interrupting whatever you’re doing.

Prefs don’t all seem to work for me, and a little ad for another product pops up whenever opening prefs…but, oh well, it still does the job.

Optional menubar readout of present available RAM, with drop down menu for manual “cleaning”, a report of how much “used”, “active”, “wired”, access to prefs.

First-time user…love it!

I've never used this product, but I like seeing it work, and when I notice that my memory is low, it prompts me to look to see if anything is open that I'm not using or don't need open at that moment. I tend not to pay attention to that, so it's handy for me in more ways than one. I'd for sure recommend this to anyone.
