Q: Problem With DMG - Legacy Image Should Be Converted

On the left in Disk Utility;

This answer should be marked as "correct".

No luck getting error -199

I tried your way but when I clicked on convert and chose where to save it I got this, I dont really know what am I supposed to do? help asap please x

Worked for me too! (OSX 10.7.5)

Fantastic, as it saved a whole stack of backup disks of older (but still important) data.

The dark side of digital archiving...

Thanks!

would it be the problem of the image formats. you can change to other formats and try again,

perfect solution, thanks :-)

In Mountain Lion 10.8.5 .... I did the .dmg placement in the Apple Disc Utility, and selected "convert" from the pull down menu (using either the "control" or option" key - I forget) .... also rename "converted" .dmg before converting to desktop .... and it opened fine.

Thanks all for the tip !

Thank you so much for this solution, I have been getting so frustrated and have been redownloading software to sort it. So easy when you know how. Much appreciated.
