I'm just put writed myself code to the end of file /usr/share/X11/xkb/symbols/ru

// Apple layout
partial default alphanumeric_keys
xkb_symbols "ru_mac" {
include "ru(common)"

    name[Group1]= "Russian Macintosh";

    key <LSGT> {	[	     less,	   greater	]	};
    key <AE02> {	[		2,	  quotedbl	]	};
    key <AE03> {        [               3,      numerosign     	]       };
    key <AE04> {        [               4,         percent     	]       };
    key <AE05> {        [               5,	     colon     	]       };
    key <AE06> {        [               6,           comma     	]       };
    key <AE07> {        [               7,	    period	]       };
    key <AE08> {        [               8,       semicolon     	]       };
    key <TLDE> {	[    bracketright,     bracketleft	]	};
    key <BKSL> {        [       Cyrillic_io,   Cyrillic_IO      ]       };
};

And add variant in file /usr/share/X11/xkb/rules/evdev.xml

        <variant>
          <configItem>
            <name>ru_mac</name>
            <description>Russian (Macintosh)</description>
          </configItem>
        </variant>
