Our review today is of CleanMyMac or Clean My Mac is basically ONYX for mac, but you have to pay $29.95 for it. (Short summery: We highly recommend the free, ONYX for Leopard or Snow Leopard, its the one we all use)

Claiming to be a clever piece of software designed to be an “all-in-one-suite utility that helps keep your Mac clean and healthy”. We’re going to give it a review today, starting first with a test. Its going to be tasked to clean my iMac.

Now, I’m not really a messy person, but my iMac’s file structure could be more organized. It doesn’t run slow (2.4Ghz with 4GB RAM) or anything, so we’ll see what it’s like after a quick wash with clean my mac.

Download & Install

First off, the download is quick. The app’s footprint is around 15MB. Even the most “spatially challenged” hard drive can squeeze this app on. Install is as usual with any mac app, just drag it over to your applications folder and ping, its done. I boot up the app.

Here’s what my machine looks like before Scanning:


I hit scan. It takes around 3 minutes.


The app managed to find 11GB extra space. Where it found it I have no idea. Well, actually I do. The interface tells me it found 7.5GB from caches, and 3.9GB from Universal Binaries. I do the scan again just to double check.

It comes out the same again. That’s amazing. This mac is only around a year old, it gets used everyday as my work machine, so its had a lot of use, but still that’s a lot to find. The app would no doubt have saved me more, as I deleted the surplus language files last year and saved a few GB’s from the unneeded files.


Here we are mid clean.

I can only imagine the amount it would save on a mac that’s a few years old, it would be a size able chunk to say the least.

Now I’ve scanned for the extra files, I can hit remove in the lower right corner, and everything’s removed. Before the install of CleanMyMac I had 117GB free, now I have 128.60GB. That’s really cool. It’s spurred me on to do a bit of spring cleaning around my computer in general.

After I cleaned my mac though, my mac was having some serious problems, programs did not launch, and lots of other problems.

Overall then, I am a bit hesitant to buy this Software, as you have to re-buy it after only 6 months. I would recommend looking at the original, and well used/tested ONYX for mac.

Download the original free (and the software everyone here at Apple Reviews uses) ONYX for Leopard or Snow Leopard
