Yes, it is often impossible to source things like Intel CPUs or chipsets. They sell them to device manufacturers only in millions. Even if you have IR rework station and can solder BGA chips you have no reliable source of these chips. It is even worse with Apple devices where they often use parts not publicly available at all (custom-made for them) and sometimes if they use a common STM32 micro, there is no firmware available to program it and it won't work without the firmware.
