[line 561-562]

//xRet = ioctl ( gFD, BLKGETSIZE64, &xImageSz );       //Linux
 xRet = ioctl(gFD, DKIOCGETBLOCKCOUNT, &pSize);  //Mac: 

[line 566]

//*pSize = xImageSz / BLK_SIZE;  // Linux: no need to divide here

B) Changes to Makefile (to use gcc instead of clang) gcc-> gcc.49; make sure you have gcc-4.9 installed with brew install gcc49
