Hoping someone's come across this - I'm trying to help out my sister with partitioning an external hard drive. She has an iMac with Snow Leopard, but the Disk Utility is missing from the Applications folder (can't find it with Spotlight either). She's going to upgrade to Mountain Lion but needs to upgrade RAM first, I would assume that when ML is installed the utility will be there. In the meantime, if she can locate her SL disk is there an easy way to extract the Disk Utility from it? I'm several hundred miles away so trying to do this remotely Thanks!
