Q: Where can i buy chip MCP79 for macbook pro 13 ??? It was down(

Chips in Mac's are not user replaceable.

Fly to China, purchase all the chips you want.

The only way I see you could get a similar chip is by checking out eBay and buying a second-hand logic board. You could get it elsewhere new/officially, but the pins might be different, so I wouldn't go that route.

Also, I guess you'd want that particular IC because you suspect it's the cause of a logic board failure? I'm curious as to how you narrowed it down to that IC?

Nice find! TS, be absolutely sure that it's the exact same IC packaging. Also, it's one of those BGA packages. TS should better be handy with a reflowing oven and correctly position the IC on the logic board. It's going to be a major hassle but it's been done before :-) Let us know if you succeed. Pics or it didn't happen :-)

Be prepared to remove the old chip which is soldered in without damaging the motherboard. Then to the new chip in if you ever find one without damaging either new chip or the motherboard.

Pity.... I was savoring the mental image of all the chips just floating off the board when he tried to resolder the one.

Perhaps your MacBook is eligible for extended warranty?

Would seem that our fellow Mac lover Alec is going to take DIY repair to a whole new level! I salute you and wish you mucho luck in your endeavor; may you be rewarded with a working Mac that serves you well for years to come. 

And here we are, getting squeamish about changing a piddly RAM stick or an HDD....
