Wow. This Dan guy must work for Apple or so. He really dont want anyone to think it is possible to upgrade a cpu.
I managed to upgrade my i5 to a i7. Bga pins on a series of cpus like haswell for example are all the same. No different pins.
I used a Haswell i7 from an death Sony Ultrabook Mainboard - CPU rarely gets damged on a Mainboard.
U just have to flash SMC with a donor file and ur good.
