Before picking a winner you should ask yourself a question: do you need a virtual bodyguard for your Mac, or is just a cleaning solution to keep the device healthy enough?
MacKeeper is the bodyguard that ups the ante even when it comes to the sole purpose of cleaning by adding live assistance into the mix. It also provides additional Mac optimization tools for free, whether that is its built-in real-time antivirus, the clever anti-theft feature or a simple program updater. Not only that, but MacKeeper is cheap and has a life-long refund policy.
CCleaner, on the other hand, is a simple yet strong cleaning solution, providing unlimited super-fast scans and repairs that can clean the entirety of your Mac’s system, or just specified parts of it. The software is even supplied with a barely-limited free version, but even the complete, unlocked program is available for affordable prices that are even cheaper if you’re looking to put additional computers under CCleaner’s protection.
