Hello, and let me first welcome you to Piriform. We are a community of Users of Piriform's products.
Sadly what we do not yet have is as many (any really) MAC ccleaner users who are readily available to aid you as we do on the Windows side. Because of this please post your Bugs and suggestions in the CCleaner for Macintosh board
The developers do read all threads and posts on this website though they do not normally comment.
