About CHM File Format

Before mentioning the list of MAC CHM readers; here is an explanation of CHM file format:

.CHM Format is the patent format by Microsoft developed as help manuals that provides instructions of softwares, ebook or other help files. Most of the ‘Help’ button in softwares pops out CHM file format where you can access instructional tutorials on how to use the program.

If you are on Ubuntu then follow this guide for converting CHM into PDF and viewing it on your PDF reader. Also, sometimes you get an error message such as ‘Cannot open CHM files’ in Windows. But most of the time, CHM formats are automatically opened in Windows OS. And now, how to view CHM Files on Mac OS?

Therefore, below is the list of the best freeware CHM readers for MAC OS.. if you know any other freeware CHM program that can be listed here then let me know through your comments.

Or one could view chm files through windows on virtualbox. Does that give better quality compatibility?
