    Hello,
    I bought my black Macbook early 2007 ( I believe that it falls under the Late 2006 category). It came with 1GB RAM and I recently upgraded it to 2GB. Also, upgraded the OS to Leopard. Foll. are the system specs:


    Model Name: MacBook
    Model Identifier: MacBook2,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 2 GB
    Bus Speed: 667 MHz
    Boot ROM Version: MB21.00A5.B07
    SMC Version (system): 1.13f3
    Serial Number (system): 4H7051JSWGM
    Hardware UUID: 00000000-0000-1000-8000-0019E334C64C
    Sudden Motion Sensor:
    State: Enabled

    My question is regarding the max. RAM supported by this system (firmware). I believe it is 2GB but is there any firmware upgrade, BootROM version that I can perform that will boost the supported memory to 4 GB or so? Also, what is SMC version? Can that be upgraded and will that help?

    I would really like to upgrade the RAM once again and put 4GB, but I do not want to buy memory unless I know for sure that it will be supported by my notebook.
    Thank you in advance.

    Your MacBook will support a maximum of 4GB (2X2GB) as is but you will only be able to use 3GB. ALternatively you can use 1X2GB and 1X1GB.

    See the MacRumors guide to Intel RAM or lookup your MacBook on everymac.com for confirmation.
