Hey! I have all my OS X applications that come with your mac on a seperate .dmg file, that's just how it happened. I'm not sure how it happened, but when I took my computer home, it just installed like that. I bought the iMac ex-display from PC World last august and it didn't come with any documentation, reboot disks or an apple remote. They say they don't have them with them, but they obviously do. I keep forgetting to mount the .dmg every time I reboot, because I'm a klutz and becoming old at a young age. I was wondering if there's any way to automatically have the mac mount the disk image? Thanks in advance! Max.
