This may take a few minutes.' On my computer, it took more than 'a few' minutes. It will say 'Creating installation medium. The OS X Yosemite installer will boot and run. * If you wish to Customize Setti ngs (change RAM, disk space, etc.), do it now. You simply select the 'Install OS X Yosemite.app' file and VMware Fusion does the rest for you.) (Note: There is no need to open the 'Package' to find the 'installESD.dmg' file. Click the Open button in the dialog box, then click Continue. * Click Use another disc or disc image., then navigate to the 'Install OS X Yosemite.app' file.

* Create a New virtual machine (File menu->New, Virtual Machine Library 'Add->New', or command-N). If it is on a flash drive, you can leave it there. * Move the 'Install OS X Yosemite.app' file from Applications to another folder. INSTALLING YOSEMITE IN A VMware VIRTUAL MACHINE As soon as it is installed, Yosemite deletes its own installer automatically from the Applications folder only, but not copies that were made elsewhere. (IMPORTANT: Even if your friend wants to install Yosemite, they must make a separate copy of the installer first. Remind them NOT to launch 'Install OS X Yosemite.app' in their Applications folder! They should copy it out of their Applications folder and put it on a flash drive or DVD ROM or hard drive for you. * If that doesn't work, ask a friend with an older Mac to get a copy of Yosemite with their Mavericks or older Mac. ( NOTE: You may not see the '.app' part of the filename.) The file is called 'Install OS X Yosemite.app'.

It will download to your Applications folder. Go ahead and 'Get' it or 'Buy' it or 'Download' it. The icon is a white circle with a large X in 'Utilities'. In the App Store, search for 'os x yosemite'. * First, try to get a copy of Yosemite from the App Store yourself, even though you are already running Yosemite. Based on that assumption, here is what I suggest: Even though your Mac came with Yosemite, I assume that you can get your own copy of the Installer from the App Store. None of my Macs came with Yosemite, so I was easily able to obtain it from the App Store. The question is how to get a copy of Yosemite so that Trixie can install it in a virtual machine.

Trixie (?) got a Mac with Yosemite already installed, but wants a second copy in a virtual machine so Trixie can practice terminal commands without fear of messing up her production machine. I think the people above are missing the point. I'm learning terminal, and I feel much better about futzing with it in a sandbox.

How do I do that? Do I download Yosemite from the App store? Will doing that create any problems? I want to install an instance of Yosemite on my VM running Fusion 7. Just got a Mac Mini with Yosemite preinstalled.
