    I'm trying to repair a fan spin issue on a MacBook Pro 5.3.
    The problem with the board is that after starting the 2nd+ time, the fan shortly spins up to full, then comes down to normal speed.

    I checked all electrical signals and compared them to another logicboard - no difference on first sight.

    So I wonder if it could be corrupt SMC data and wanted to ask if it is possible to read the whole SMC of a working board and flash it to the faulty one. Because Apple has not released any SMC update on their website, I don't know where I could get a SMC dump.

    Thanks
    Alex

    ReadSMC for EFI, a tool to enter read SMC keys from EFI shell on real Macs

    I wrote a little EFI tool to read SMC keys from real Macs from an EFI shell running on the real Macs. I made 32bit and 64bit versions. It also reads the SMC Signature out and shows it. Usage example: ReadSMC.efi OSK 31 It show: OSK0: [ 6f 75 72...
