    ok, So I have a read-only DMG that I need to be able to edit the contents of.
    I have duplicated this image as many ways I can think of.

    I have used Carbon Copy Cloner to create a (Read-Write) sparse image of it, when I get info on the DMG it says I (my user) have read-write access. However I dont! ugh!

    I tried to "Convert" it to read-write using disk utility, no luck...

    I even went to the specific folder I need write access for and tried to chmod it (777) and it comes back, "Read-only file system"

    How do I convert a Read only DMG to a Read/Write disk image?


    Thanks,
    :)

    Make read/write image.
    In Terminal, "cp -R /Volumes/oldDMG/ /Volumes/newDMG/"

    Should I mount the DMG first then use the location of the mounted image, or the actual location of the image on the drive...

    EDIT:
    Simpler,

    should I drag the white icon to the terminal, or the white icon with a hard drive on top of it?


    EDIT2:
    rereading it, it looks like I need to drag the mounted image, question is, how do I define the location of the actual DMG for read-write version?

    ok I did a straight DMG copy, where I actually dragged the .dmg file onto the terminal, but that gave me the same results as before, When I get info it shows I can read write, but when I mount it, I still doesnt give me write access!
    :eek:


    EDIT:
    ok, I used a little app called DropDMG to convert it to read-write.

    Thanks anyway!
