    Going from Snow Leopard to Mountain Lion
    I refused to update my OS X even though I got a 2011 aluminum MacBook and stuck with Snow Leopard. However, now I want to use iCloud to so I have to upgrade. Will the $20 download of Mountain Lion retain all of my settings if I install it? Anything to look out for? I have Time Machine backups.

    Settings include desktop, preferences, the "look" of your OS X, etc.

    Specs:
    Imac 27", i7 3.5GHz, 3TB Fusion drive, 32GB memory, macOS Sierra.
    No problems at all.

    To have Snow Leopard it must be the early 2011 model. It will update fine BUT be aware any older software such as Office 2004 etc which are PowerPC will not run as no more Rosetta. Just download from the App Store, make a USB bootable thumb drive using LionDiskMaker before running the installer, install without formatting the drive.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I thought that leopard was the last powerpc supported version of OSX? You should be fine, you will most likely have to reverse the scrolling in system preferences though (Unless you decide you like it) but that's easy.

    The default Snow Leopard install doesn't support PPC applications, but will if Rosetta is selected during a customised install or if additional installs is later selected and run from the install DVD.

    I run a variety of OS X versions on different Macs, and am quite happy with Mountain Lion.
