It has worked great, like every other Crucial brand product I have ever bought. My next upgrade purchase will likely be a Crucial solid state drive.
"Free" : If your "Free" memory is low (or 0!) you probably need more memory.
"Page Outs" : If the "Page Outs" is high, this means that your computer is using hard disk rather than RAM for memory functions and produces a severe loss in speed.
"Swap Used" : This gives a rough estimate of how much hard disk is used for RAM. This will give you a rough idea of how much RAM you should add. i.e. if this is 4 GB, then you should add at least 4 GB.
You should check these numbers while doing the types of activities you normally use your computer for. Not just at idle with nothing running!
As far as this item goes, Crucial is a known Apple-friendly RAM and is unlikely to give you any issues. It is also a high quality manufacturer and is much more reliable than some cheaper brands. Remember, RAM is dirt cheap these days so don't save a few $$ to buy inferior quality RAM! You should just not buy any if you are going to buy a terrible brand.
iMac install is really easy! You can find many manuals on the internet (I prefer iFixit). Don't be intimidated buy installing it. You can save a lot of money by doing it yourself. If you feel uncomfortable, then by all means have someone qualified to do it for you.
The only thing you'll need is a #00 philips screwdriver. I bought mine from Radio Shack for $7 (it came in a kit).
Then, take off 10 screws on the bottom, pop off the aluminum plate, pop off the existing RAM, stick the new RAM in its place, and voila! There are several Youtube videos showing the entire process. It took me 15-20 minutes from start to finish.
This has different part numbers from the Crucial website, but works just the same.
