    I have a program that is old and requires the disc to be present while in use. I am trying to use it on a macbook air. I'm sure you can see the problem here. Money is tight, I can't get the superdrive right now so in the meantime I wanted to copy the disc to a flashdrive as an iso. I did this using MagicISO on a pc. When I try to convert it on the mac using disc utility I get the error "Unable to attach (not recognized)". I have no idea where to go from here. Any help would be appreciated, however, I cannot afford a program to do this. Thanks in advance.

    Can you just transfer it as a dmg onto the flash then copy it over onto the MBA? The dmg should auto-mount as though it were a disk once opened.

    An iso should automount when you double-click on it or by using Disk Utility. You shouldn't need to convert it to anything different.

    Sounds like one of three things is going on here (you can determine which it is by looking at your Mac's Console logs):
    1. The format of the image is incorrect (the extension is ISO but the internal file format is not).
    2. The image file system is one your Mac does not know how to load.
    3. The image itself is corrupted.

    In the past I have found that Toast manages to mount images that other apps refuse to do so.
