Hello. I cannot open DMG files. I have had the problem with a download of Adobe Photoshop and the Combo Update for Mac OS 10.4.10. I have re-downloaded both files. (When I download, I am getting two separate files for each, one dmg, and one dmg.part, which the OS seems to think is a quicktime movie file. Is this normal? I don't remember.) Anyway, this is the error: The following disk images failed to mount; name of file, not recognized.
I have tried most of the fixes found on the site, and none of them have worked for me. Here is a short run down of what I have tried: Running Disk Permissions Repair Restarting Opening from Stuffit Opening from Disk Utilities Opening from Mount (downloaded from Internet)
I thought that I read that downloading the Combo Install would fix the problem with the Disk Mount, but I cannot open that either.
