Mac error 'no mountable file system'
Posted on 2011-03-03
I have a client in another state who cannot install software packaged in a .dmg file.
This happens with files from either a local flash drive or downloaded from the Internet.
The computer is a mac book running OS 10.3.9 - a version of OS X that I have little experience with.
The error message he gets is: no mountable file system
The occurs when he tries to run/mount a file with a .dmg extension.
This has happened with four different files: a printer driver stored on a local USB drive, the same driver downloaded from the vendor's site, a screen sharing program downloaded from my personal 'help' site and the same screen sharing program downloaded from the vendor's site. All files have a .dmg extension.
Thus, I do not think the problem is with the files themselves but appears to be something in the way the machine is setup.
I only have telephone contact with him so cannot see the screen or work with the machine's preferences/CLI to study the problem.
