Nektony Memory Cleaner

Works as advertised on my old MacBook pro 2013 had not bugs or any glitches

Works great! So many mac cleaning apps out there but this does the job perfectly, been using it for 3 weeks now, and I'm happy with it, especially with limited memory on my old iMac 2017 27".

Interesting how nearly EVERY review below was created the SAME DAY that the user joined MacUpdate, and they haven't posted or downloaded anything since?. If you're going to provide FAKE reviews, at least make the reviews a little later than your join date!

Very unobtrusive app that does a great job reclaiming memory. Also amazing to see how inefficient some apps are (if not most) about releasing memory back to the OS.

Love this app, I have an M1 with limited memory, so...

It is a wonderful product ,I like it so much

Gets the job done !!!

One time investment. Does the job very efficiently in just a few clicks.

great

It definitely increases the power of your computer at least 2 times. Let me tell my story as Memory Cleaner saved my life: I was using Photoshop, Premiere Pro and many programs simultaneously. Since my computer is a Mac Air with 8 GB RAM, I could not mount 4K video. When I saw Memory Cleaner I thought it wouldn't work, 'After all, my computer had no power. I thought, 'What can a software do?' But out of desperation, I wanted to try. The result surprised me a lot. My computer went from a weak MacBook Air to a mighty Macbook Pro. Now I bought Macbook Pro M1 and installed it again. The result is great Thank you to the developers of Memory Cleaner.

Amazing tool.

Solid. Runs in the background and automatically keeps memory in check.

A very simple and convenient application that helps to reduce the time spent searching for a problem. Constantly monitors "heavy" applications and cleans up wasted memory.

Eine sehr schöne Einfache App ohne Schnick Schnack. Funktioniert Prima und tut was sie soll. Läuft Supi mit Big Sur.

Nice app! But does NOT launch at system startup when choosing that option in the preferences under Mojave 10.14.6.

This app is extremely useful, effective and enjoyable. I have a 2017 MacBook Pro with 16 GB of RAM, and the memory regularly becomes fully or so while only using one web browser (common web pages, nothing special). I notice the situation as everything becomes super slow. This tool not only cleans the RAM, but does it automatically and for free. Plus, it provides key insights that the Apple ActivityMonitor app fails: RAM usage by app (the Apple utility provides RAM usage by process, which in the context of a browser with many tabs corresponding each to a process, is pretty useless). I was using before CleanMyMac, but it is far less convenient and super time consuming (no automation), and much less informative (no stat by app).

open Terminal window and when prompted, type "sudo purge" without the quotes. system will ask for your admin password and between 1 and 10 seconds later, your RAM will be purged - with decreases in Wired/Active/Compressed and Inactive use and an increase in Free RAM.

Recently I am using a powerful all-in-one tool to optimize and clean up my Mac , and I'd to share for you, simple clicks(https://www.imymac.com/powermymac/) to free up your Mac storage space, uninstall apps, protect your privacy, speed up your MacBook or iMac.

This is an OMG great app! It has one major advantage over similar apps...you always know how much RAM each and every one of your apps is using all of the time. Great for spotting RAM hogs and leaks. Extremely flexible for freeing up and recovering RAM so that you will likely never run out of it.

If you are running a DosDude hack on a "obsolete Mac" in High Sierra you need this little app.
