Does any one know if "Memory Diag - Clean and Optimize Memory Version 1.1.1 would work on my IMac Intel Core i5 2.7 GHz OSX 10.95? It is free at the App Store. Thanks.

Why do you think you need it?
Here are some opinions at reddit

OS X knows what should and should not be stored in RAM, much better than either of these utilities do. The reason you normally see your RAM full when as rest state is simply because free RAM is wasted RAM. Undoing any of these optimizations is going to make performance worse, not better.

Let the OS manage the memory. You'll get better performance if you do.

Now, if you are in the yellow, or red, that's a different story. But in that case, neither of these apps are really going to make much of a difference. Instead, you have to consider if everything you have running simultaneously is necessary. If the answer is yes, or if all your memory (reflected in the Memory Pressure graph) is used by a single app, then the answer is to add more memory.


It doesn't seem to be malicious, and may be interesting to look at.
But in most cases it doesn't seem to be helpful for speeding up your Mac.

WOW! Thanks Jenny. I am not having any memory problems. I didn't think I needed it. I just thought it might be useful to clean up like defraging does on my old XP computer. I don't know if I have a cleaner on my Mac. Are there any free cleaners out there for IMacs? Thanks again. wave

OSX is not sensitive to fragmentation ("fragging") the way Windows is. If you're having problems with your hard drive being slow on a Mac, it's more likely that the hard drive is going bad or that the drive is too full.

Here's an discussion on Apple forum about whether there is a need to defrag on a Mac
https://discussions.apple.com/thread/5510986

The short answer is that OS X takes care of itself better than Windows does -- and doesn't need the same maintenance.

OSX fragments the free space rather than the data. In either case there is less to worry about if the HDD is not allowed to get too filled.

Gosh that's good to know. Thanks Jenny and Collector. It's nice to be able to come here and learn about my iMac. I love it. It's my first Apple computer. I'm still getting to know it. I'm amazed at how easy it is to use and how well it takes care of itself! Thanks again Jenny and Collector! thumbsup
