Overview & Conclusion

I was very impressed with this app. It is made by Nektony which also makes App Uninstaller, an app that I have used for several years.

Memory Cleaner X checks for duplicates, junk, very old material, and unused applications. When you give it the go ahead, it cleans it all up with the tap of a key. If you have ever gotten the warning that you are running out of memory you are familiar with the problem.

Two notes of importance:

  1. Out of 108 reviews on the apple store, 92 reviewers gave it a perfect 5 stars.
  2. I noticed that every time I play a game on my Mac, the application immediately deletes all the junk created by all those games I lost.

Review Details

The following is the image I got the first time I opened the App. Wow. I had almost reached that “full up” problem.

This next image shows my memory usage after I ran the program.

As you can see there is a great deal of improvement.
