What users say about Nektony Memory Cleaner
Value: 5.0
My very expense MacBook Pro was running slowly and when using Photoshop (important, since I'm a photographer), lack of storage would prevent me from saving files. I don't store anything except for my work-related softwares on my computer so I couldn't figure out what was using all my storage. Another Mac-cleaning program, a free one, was NOT cleaning up my computer in any meaningful way. I decided to purchase MacCleaner Pro and am SO HAPPY I did. As it turned out, a video editing software had created an enormous clog of cache files. I would never have been able to manually clean that up on my own. Thanks to MacCleaner Pro, I am back to having ample free storage and memory on my MacBook, and my computer is operating just as I intended it to, a workhorse machine that moves quickly. Thanks, Nektony.

Have an earthquake shaken Macupdate today ? Google ads are everywhere...install this...install that..install..install...activate...just a total flood. Applications don't show "last update", mess is everywhere. How are we supposed know which application is updated and which application has not been updated in years ?

Although I have other utilities that display and manage my Mac's memory, Nektony Memory Cleaner is my program of choice. The UI is attractive and easy to understand, and the company seems to know Macs inside and out. While this is a free utility, the company makes Mac Cleaner Pro ($) which includes terrific companion programs, including App Cleaner & Uninstaller, Duplicate File Finder, and Disk Space Analyzer, all of which are top-notch! And they're already Sonoma-ready!
