This is so stupid and so obviously not legit.
-The Mp3 player is definitely not iTunes, Windows or Mac.
-The trash can is on the desktop, while it should be in the dock.
-All of the files and folders are on the left side of the computer, while almost all macs use the default of having the files on the right. Windows places them on the left.
-In the Apple menu, there is no force quit, and there is also a software update item, which is not in OSX.
-In OSX, when you're on the desktop, the upper left Menu next to the Apple menu is the Finder, however this picture has it shown as "Desktop".
-The System Properties clearly says Windows XP, and even if Marklar worked *over* Windows, you wouldn't see the System Properties window, because you'd be in Marklar, not Windows.
-The second picture, in the upper right, shows a very windows item that is usually, I believe, on the lower right on Windows, where it shows you what programs are open.
-The window in the first picture is obviously a Windows window. Wouldn't a Marklar window look like OSX?
-And finally, it's just plain and simply not Marklar. How would you or someone you know have a copy? Also that's a stupid explanation, that it's installed on top of Windows. THAT MEANS IT'S A SKIN OR AN EMULATOR. If Apple did indeed make Marklar, why on Earth would that make it do that it has to be installed *on top* of Windows? That would make it totally pointless. You'd have to purchase two OS's to use Apple's, and it would make it slower. No, if Marklar exists, it would be a native x86 program, it wouldn't have to install over anything.
