CHM, Microsoft Compiled HTML Help is a Microsoft proprietary online help format. It was introduced as the successor to Microsoft WinHelp with the release of Windows 98, and is still supported in Windows 7.

Nowadays, most of the help documents and manuals are in CHM format. Undoubtedly, we can view CHM files easily while running a Windows operating system, but what shall we do if we want to read CHM files on Mac OS X operating system (especially on the latest OS X Lion)?

To view CHM files under Mac OS X Lion for free, I will recommend you have a try with Free Enolsoft CHM View for Mac, a useful utility which helps Mac users to easily and quickly view CHM files on a Mactonish. In addition, with this useful Mac CHM Viewer, you can also freely zoom-in and zoom-out the font size, search in the CHM file, navigate through Chapter/Index or read the CHM ebook on fullscreen model or content tree mode as well. It’s a totally free application with some additional functions which includes:
