Keeping your Mac in top shape can be hard over time, as various clutter and digital debris begin to take residence on your system. Thankfully, there are a wealth of tools available to rectify this malady and get your iMac or MacBook back in fine fettle once more. We gather together some of the best clean-up utilities for macOS.
First a word of warning. While normally the fact that an app is in the Mac App Store would mean that it has been heavily vetted by Apple, and therefore we would recommend it as safe, there has been a case of an app - specifically one used for cleaning your Mac - being found to be stealing data from machines.
The app, Dr Cleaner, was found to be collecting data from Macs and sending it to a specific address. Apple has since removed it from the store. We recommend that anyone using Dr Cleaner should stop doing so now.
One heavy hitter in the clean-sweep stakes is CleanMyMac 3 by MacPaw. As you’ll have already guessed, this is the third iteration of the popular utility that comes from a stable of other useful tools such as Gemini 2 (Duplicate files remover), CleanMyDrive 2 (Disk manager for internal and external drives), and Hider 2 (data encryption for your files).
CleanMyMac 3 has a simple layout that offers a variety of functions. These include a general system clean that optimises space by removing temporary files that could be lingering, as well as slimming down unnecessary parts of applications and removing any odds and ends left behind after uninstalls.
There’s also the ability to search through your Photos, iTunes, and Mail folders to remove and clean up waifs and strays that could be slowing down your system.
CleanMyMac 3 is a comprehensive package, which offers several additional tools for uninstalling apps cleanly, removing various extensions, improving disk performance, and digitally shredding files that you don’t want anyone to revive.
All of this functionality doesn’t come free though. There is a trial version available, but it restricts the app to only remove files up to a maximum of 500MB, so you’ll want the full version and that will set you back £34.95/$39.95 for a single-license or £54.95/$59.95 for use on two Macs.
The license can be transferred to a new machine, so long as the previous install is deactivated first.
MacPaw does run promotions regularly, so check its webstore for deals. At the time of writing you can pick up a bundle of CleanMyMac 3, Gemini 2, Hider 2, and Wallpaper Wizard 2 for a very reasonable £45.95/$55.95.
As we go to press there is also the news that a new version CleanMyMac is due to be released in September 2018, so check back soon to see what it brings to the table.
If you’re more of a visual person, then DaisyDisk is an excellent tool for seeing the contents of your drive in a colourful and interactive graph. The files are sorted into various groups such as Large files, Documents, Music, and Downloads, each of which are allocated their own colours and spokes that show how much space that area is taking up.
It’s a good at-a-glance method for understanding where all your space has gone. Each section can be clicked to bring up another circular breakdown of its contents, with each sector representing a file. These can be previewed to see whether you want them or not, and if it’s a case of the latter then you simply drag them to the bottom of the screen where all your junk files are stored.
When your pruning is complete, hit the Delete button and they will be dispatched without a hint of mercy.
If you visit the DaisyDisk site then you’ll be able to download a trial version that shows you how the app works. This is useful, but as the delete feature has been disabled you won’t be able to clear out any files. Instead, go for the full-blown version which costs £9.99/$9.99.
This powerful app not only offers the standard disk clean-up features like removing duplicates, scanning for large files, claiming back memory, and general performance enhancing duties, but also includes Virus and Malware scans to keep your Mac free from malicious software.
While it’s certainly a comprehensive suite, the power under the hood could prove a little too much for beginners. We’d also heavily recommend, as with any app in this roundup, that you make a complete backup of your system before you begin deleting files.
MacBooster 7 is available on a free 14-day trial, but after that it costs $39.95 for single Mac license or $59.95 for three Macs.
App Cleaner & Uninstaller
Finally, there’s the simple and easy to use App Cleaner & Installer from Nektony. This lightweight app does a good job of clearing out the broken links, files, and other gubbins that get left behind when apps are uninstalled. It also, as the name suggests, allows you to uninstall apps cleanly from the get-go, and set which ones launch at start up.
The free version does most of these tasks, but if you pay £4.99/$4.99 for the Pro upgrade you’ll also be able to remove system extensions, executable parts of files, and uninstall apps, plus the ads that adorn the free version disappear.
Easy to recommend due to both its price and quality.
