I have downloaded a couple of program files that appear to be for mac os. The files are of .dmg type and I don't know how to open them on my macintosh? Even .sit files when expanded show as .dmg files. I don't have a clue. Can anyone offer a little advise?

Thanks.

.dmg's can be opened in OSX by Disk Copy (in the utilities folder). They usually can't be opened by the OS 9 or earlier Disk Copy.
