Easy to use and fast — and it works!

I was skeptical about the apps claims. To precursor, Google Chrome on my Mac was infected with a Virus (Safari was not). The upshot is that it slowed down my new iMac immensely. Familiar with this app on Windows, I gave it a try on the Mac. It did everything that it claimed to do and it did so quickly, with miminal intervention or thought on my part. After the cleanup, everything was running smoothly; nothing was affected by the files Disk Cleanup deletes. The system now runs significantly faster after the cleanup. It’s worth the $6.95 paid for the app. I give it five enthusiastic stars.
