Carbon (a bit old) or Cocoa (the new one).

How do you think Lazarus can run on Mac with Carbon interface (and probably Cocoa in the future)?

No, Linux practically has no underlying GUI library. Despite nearly all Linux distros are distributed with it, X11 is not part of Linux. When Wayland (and that another new effort from Ubuntu team) makes its way to enter Linux world deeply, X11 might be history.

sorry i didn't understand  , do you mean its possible to use Carbon and Cocoa functions ?

More information on the Mac OS X API is available from

• https://developer.apple.com/library/mac/navigation/ (the official Apple documentation}
• http://www.pascal-central.com/merlinx.html (Carbon demos in Pascal)

Usually, however, you don't have to care in Lazarus as the LCL provides a broad spectrum of funtionality. For special purposes it may be useful to consult pages like the two from above.

I think that Leledumbo wanted to say that Lazarus (that is a Carbon app in the current Mac version) couldn't run on a Mac, if there were no header files.
