Total MacBook Upgrade: CPU Replacement
Most owners of Apple laptops know that the processor in macbooks is soldered on the board and is not replaceable. Therefore, when buying a poppy, you need to immediately choose a complete set with the desired processor.
But this information is not entirely correct. Yes, the processor is really soldered, but you can replace it, like a regular BGA chip. And even if replaced with a more powerful one, everything will work fine. The only condition is that the processor must be a compatible series, i.e. have the same system bus frequency. This is necessary for normal work with the chipset on the motherboard. And other characteristics of the processor: frequency and cache do not matter. Thus, you can get an upgrade-pump percent.
This statement is not empty verbatim, we repeatedly carried out such an operation in our service center. True, they tried to do it only on the already outdated Macs with Intel Core 2 Duo, models of 2008-2010. Theoretically and with newer processors of the Core i series there should be no problems. But we have no such experience yet, we hope that we will try soon.

So, we will tell in more detail. The following models of poppies will be discussed: MacBook A1278 2008; MacBook A1342 2009-2010; MacBook Pro 13 ”A1278 2009-2010; MacBook Pro 15 "A1286 2008-2009; MacBook Pro 17" A1297 2009
In these models, various mobile processors Intel Core 2 Duo were installed, with a system bus frequency of 1066 MHz. Intel delivered such proces in the BGA version (BGA479), which Apple used in its laptops.
The question arises: where to get such a percent to replace? There are three possible solutions:
1. Buy on eBay or in China the already ready BGA479 format.
2. Solder the percent from the donor board and then restore the BGA balls.
3. The most interesting in our opinion, and the most accessible, is more detailed about it.
The processors of the BGA479 format are almost the same as those for the PGA478 socket. But at the same time, the latter are more widely distributed and accessible. Mobile Intel Core 2 Duo processors for the PGA478 socket were massively put into ordinary PC laptops. Therefore, they are easier and cheaper to buy. There are only two fundamental differences between the PGA478 and BGA479:
1. In PGA478, instead of balls, there are contact legs. But they are simply soldered, they can be easily soldered even by a soldering iron.
2. At PGA478 one pin less. But this contact is not functional, it is a power pin that is duplicated many times on the other legs.
Thus, BGA can be made from a socket processor. In the photos below we have demonstrated this process.
1 photo. Processor for socket PGA478.
2 photos. We unsolder the contact feet.
3 photos. Solder BGA balls (reball).
4 photos. Ready for soldering BGA processor.
We will not describe the procedure for replacing the processor; it is no different from replacing, for example, a video chip, such material is complete on the network.
In conclusion, we present a list of compatible Intel Core 2 Duo, which can be installed on Macs 2008-2010
Intel® Core ™ 2 Duo Processor:
T9400 (6M Cache, 2.53 GHz, 1066 MHz FSB),
T9600 (6M Cache, 2.80 GHz, 1066 MHz FSB),
P9500 (6M Cache, 2.53 GHz, 1066 MHz FSB),
P8600 (3M Cache, 2.40 GHz, 1066 MHz FSB),
P8400 (3M Cache, 2.26 GHz, 1066 MHz FSB),
P7350 (3M Cache, 2.00 GHz, 1066 MHz FSB),
T9800 (6M Cache, 2.93 GHz, 1066 MHz FSB),
P8700 (3M Cache, 2.53 GHz, 1066 MHz FSB),
T9550 (6M Cache, 2.66 GHz, 1066 MHz FSB),
T9900 (6M Cache, 3.06 GHz, 1066 MHz FSB),
P8800 (3M Cache, 2.66 GHz, 1066 MHz FSB)
