    Is this ok? I looked it up and saw a youtube video of someone else s mac running Yosemite like this.

    also, I notice when I view my hard drive in disk utility, in the hierarchy structure, both the top and bottom read, Macintsoh SSD. While installing Yosemite, I did a hard drive erase before installing the OS.

    I notice on my other macs, the top would be some technical or brand nae of the hard drive, and below would be the name of the hard drive.

    Is there something wrong how I have it after installing Yosemite? I did a verify disk, and it appears to be ok. Does the naming structure matter? I looked at my hard drive on the system profiler, and there it shows the more technical name of it, something like apple media.

    I went through a bit of an ordeal with the laptop, so I am nervous that it is ok now.

    That is the new standard boot screen you're seeing.

    The difference you're seeing in Disk Utility is because Yosemite changes the partition from a physical to a logical, using CoreStorage. When you click on the volume for your internal (the next one in the hierarchy), you see in the info at the bottom of the window will show it as a Logical Partition. The top level, where you used to see the physical device, is now a Logical Group.

    Functionally, you shouldn't see any difference. Doing Restores to/from the partition work normally, and you can change the partition size or add another live, as before. And, if you install Yosemite in a physical partition alongside of other physical partitions, it won't use CoreStorage.

    I still haven't heard a why for this. It's more flexible, I suppose, and is required for both File Vault and Fusion Drives.

    You can view details on the physical and logical volumes by using Terminal and the following commands:
    To see the mount points:
    Code:
    diskutil list
    To see the CoreStorage Logical/physical volumes:
    Code:
    diskutil cs list
    (If you're not familiar with commands in Terminal, each of the above is executed by hitting <return>.)

    Oh, and yes, you are seeing the new boot screens, bring them inline with iOS.

    thanks for this explanation, I was worried that I may have done something wrong during the installation process.

    same with the bootup, I thought something was wrong there as well too. it seems yosemite is trying new ways of doing things, I am ok with this, as long as everything functions properly.
