I can see, from the Analysis Results, that CCleaner would delete roughly 153 MB of files from iTunes, but I don’t know exactly what files it would delete. The software doesn’t tell what files it’s going to delete, so I have been reluctant to allow it to clean my Applications. Piriform has a documentation page for CCleaner, but it is applicable primarily to the Windows version. The UglyĪs of now, there is absolutely no documentation for CCleaner for Mac. After roughly a week, though, Piriform had a new release that seems to have alleviated those problems. For example, the app would run perfectly fine on my Mac mini at home, but hang when I tried to launch it on my work iMac (both running 10.6.8). When CCleaner for Mac first came out of beta, the app would run on some Macs, but completely freeze on others. Since Piriform is new to the Mac, they’ve had some difficulties getting their software to run reliably on the Mac. Everything you see in the app is available for use, absolutely free. There are no banner advertisements within the software, no nag screens asking for donations, and no crippled features. The app, like all of Piriform’s software for home computers, is available as a free download. CCleaner for Mac brings a variety of important system optimization utilities into one application, and provides a clean user interface for accessing those tools and utilities. Piriform responds quickly to bugs, once users let the developers know about those bugs. The app runs well now, after a rough period just after the product’s launch. By carefully choosing which cookies to erase, you can clear out the clutter left behind by web pages, but not have to re-type your username and password to log into Facebook. If you know about cookies, and which ones you might use on a daily basis (such as the one that holds your authentication to Google, for example), this is a very useful set of options.

Erase Free Space gives you the option to write over empty space on your hard drive by zeroing out the space, performing a 7-pass wipe, or performing a 35-pass wipe.įinally, CCleaner for Mac allows you to drill down into your cookies, choosing which cookies should be erased and which should be kept. The Repair Permissions tool works just like Repair Permissions from Disk Utility.

You can choose an Uninstaller, which you can use to remove apps you no longer use, a Repair Permissions interface, and an Erase Free Space tool. Other than cleaning temporary files, CCleaner for Mac also provides quick access to a number of system untilities from within the app. Similarly, if you click the Applications tab, CCleaner will display options for other web browsers (such as Firefox, Chrome, etc.), as well as checkboxes to clean temporary files for other applications installed on your Mac (such as iMovie, iTunes, Microsoft Office, and so forth.) If you want to clean these applications in addition to OS X itself, you must click Analyze and Clean from the Applications tab. After it finishes analyzing your Mac, it will show how many files will be deleted, and how much disk space will be recovered. Once you have the settings you want, click Analyze, and CCleaner will work for a few moments. You can pick and choose which items to clean by deselecting individual items’ checkboxes. The app will also empty the trash and clear out a number of caches and log files. The app will clean Safari’s Internet cache, history, cookies, and download history. When the app is first opened, it shows cleaning options for OS X itself. FeaturesĬCleaner offers a number of features that will help keep your Mac clean and optimized. For the purposes of this review, I tested the app on OS X 10.6.8 and OS X 10.7.2. Installing CCleaner is quick and easy System RequirementsĬCleaner for Mac will run on any Mac with OS X 10.5 or higher. CCleaner is not available from the Mac App Store, since it needs more access to the Mac’s file system than a sandboxed Mac App Store app is allowed. This makes installation quick and easy, in keeping with the tradition of app installation on the Mac. The app uses the typical install process of dragging the icon to an alias of the Applications folder. The utility also includes features to repair the permissions on your filesystem, wipe free space and clean Chrome’s omnibox. The final release for Mac offers cookie management, allowing you to choose to keep all of your cookies, some cookies for persistent logins, or (by default) clear all of your cookies. The app adds cleaning capabilities for Safari, Google Chrome, Opera and Firefox. CCleaner for Mac has been in beta for a while, but the final version of the utility was released on January 30. One of my favorite utilities for cleaning up the Windows PCs my clients bring to me, Piriform’s CCleaner, has come to the Mac.
