The test machine is a 2018 Mac Mini six-core Intel i7 3.2GHz. I ran a clean with all the options in clean and misc ticked, as well as choosing to verify the file structure.

Unlike some of the paid-for programs available, you won't get many progress bars or a report back on how much data or how many files have been removed. When you click execute, the process begins, and you may need to restart a couple of times. Be careful with recent items, though, as if you regularly use it to access files you open a lot, you should make sure it's unticked. In the misc section, there are options to clear old font caches and junk. Cache files, cookies and log files are fairly safe options to remove, and as they can become fairly large will have a positive impact on how the Mac runs. You'll also find an options button that allows you to fine-tune what you want to remove. There are four options here, system, applications, internet and logs. Most of the time, however, you'll probably go straight to the cleaning section at the bottom. From here, you can verify the file structure and rebuild the spotlight index as well as your mailboxes. The maintenance tab is your first port of call if your Mac is starting to run a little slowly.

It is split into different tabs depending on the type of maintenance you want to carry out Luckily the dashboard is simple, clean and easy to figure out.

Massively customisable, it allows you to verify your start-up disk, reorganise your file structure, rebuild databases, adjust and repair file permissions and recreate indexes. OnyX was developed in 2003 by Joël Barrièrehas, and he has worked steadily on it ever since, updating it for each new version of OS X.

The app brings together some of the Mac's inbuilt functions allowing users to correct problems and gremlins in their macOS. Released during the Jaguar 10.2 version of the OS X, it has an impressive range of functionality.
