Font-face not working in MAc

I created font-face using http://www.fontsquirrel.com/fontface/generator. I have created myriad pro semi bold and italic fonts using it for the website. The fonts are coming fine in PC machine but on the Mac the links are not looking as Myriad pro semibold.

Here is the link to the site where you can see.

font-face code :

@font-face {
font-family: "MyriadProSemibold";
font-style: normal;
font-weight: normal;
src: url("myriadpro/myriadpro-semibold-webfont.eot?#iefix") format("embedded-opentype"),  url("myriadpro/myriadpro-semibold-webfont.woff") format("woff"), url("myriadpro/myriadpro-semibold-webfont.ttf") format("truetype"), url("myriadpro/myriadpro-semibold-webfont.svg#MyriadProSemibold") format("svg");
}
@font-face {
font-family: "MyriadProSemiboldCondensed";
font-style: normal;
font-weight: normal;
src: url("myriadpro/myriadpro-semiboldcond-webfont.eot?#iefix") format("embedded-opentype"), url("myriadpro/myriadpro-semiboldcond-webfont.woff") format("woff"), url("myriadpro/myriadpro-semiboldcond-webfont.ttf") format("truetype"), url("myriadpro/myri开发者_Go百科adpro-semiboldcond-webfont.svg#MyriadProSemiboldCondensed") format("svg");
}
@font-face {
font-family: "MyriadProSemiboldItalic";
font-style: normal;
font-weight: normal;
src: url("myriadpro/myriadpro-semiboldit-webfont.eot?#iefix") format("embedded-opentype"), url("myriadpro/myriadpro-semiboldit-webfont.woff") format("woff"), url("myriadpro/myriadpro-semiboldit-webfont.ttf") format("truetype"), url("myriadpro/myriadpro-semiboldit-webfont.svg#MyriadProSemiboldItalic") format("svg");
}
@font-face {
font-family: "MyriadStdTilt";
font-style: normal;
font-weight: normal;
src: url("myriadpro/myriadstd-tilt-webfont.eot?#iefix") format("embedded-opentype"), url("myriadpro/myriadstd-tilt-webfont.woff") format("woff"), url("myriadpro/myriadstd-tilt-webfont.ttf") format("truetype"), url("myriadpro/myriadstd-tilt-webfont.svg#MyriadStdTilt") format("svg");
}

This post: CSS @font-face not working with Firefox, but working with Chrome and IE may help. I know it relates to Firefox, but you may find the solution there.

Update: Also, you're calling the stylesheet with your @font-face property in it after you call the stylesheet which you're using it in(voucher2.css). From what I saw you don't call any Myriad font in "menustyle.css".
