If you want to clean your Mac but would rather give your preferred optimizer a spin before purchase, there are often plenty of options. It’s typically possible to download a free version of the software, which is usually limited, or try the unlimited solution by opting for the money back guarantee should you decide not to use the software anymore. Quite interestingly, you can have both options if you pick MacKeeper.
You can opt for the free version of MacKeeper with which you can scan and clean a limited amount of junk files from your computer. However, if the program malfunctions and the issue cannot be solved then you are protected by a virtually unlimited money back guarantee, meaning the subscription can be cancelled to receive a refund – though stipulations affect whether that’s a full or partial refund.
