I did find bits and pieces here and there on google on how to mount a .dmg image but not any complete and final description in the manual under 4.4.1 - it seems its all assuming iso images. Coming from Parallel Desktop 5 and just playing with the VB there is still a good path to walk, but as I am favoring free as in beer - I will remain ....I hope this question hasn't been asked already, but i certainly could not find it on the forum.

Virtualbox Guest Additions Mac Os
I was able to mount a previous .dmg file successfully in virtualbox and it ran well in the Mac guest.
Why doesn't this one work and how can i fix it?
Thanks in advance.
