MacCare

MacCare is a program designed for Mac users who wish to easily and effectively optimize the performance of their computers.

This utility helps you clean up junk files from your Mac, uninstall third-party applications, and protect you computer from malware threats.

You can work with this tool whenever your Mac is running slow and you wish to find out the source of this problem. The app scans your system and immediately reveals all found junk files, unused binaries, broken preferences, and many others.

This program also performs a full scan to verify Mac's signature, check the SMART status, detect trojans, etc. Furthermore, it provides you with several hardware details which come in handy if you wish to contact the Apple support team and need to offer information regarding your Mac.

Another advantage is that this app also allows you to clean unnecessary files from your iOS device. You only need to connect your gadget to your Mac, start the scanning process, and click the Clean button.

Only two things bothered me about this tool: it lacks pause and resume options for the scanning process and it doesn't let you choose which type of files to clean up (removes all found junk files).

Nonetheless, this program offers you a simple way to optimize the performance of your Mac. So, I'd say it's worth a try.
