This may be a stupid question, but before I do something even more stupid, I figured I would ask. I follow MacTracker and I had identified my model as in my signature, but here are the details: Model Name: MacBook Model Identifier: MacBook4,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 3 MB Memory: 6 GB Bus Speed: 800 MHz Boot ROM Version: MB41.00C1.B00 SMC Version (system): 1.31f0 Now MacTracker has an "Early" and a "Late" version 2008 of MacBook 4,1 listed. Since the "Late" is listed as only having the 2.1 GHz processor . . . I just assumed that I am "Early." Neat. MacTracker does not list a firmware update. However, being curious, I decided to check anyways and found this page: Support: Apple Firmware. It does not seem to list my Boot ROM Version. Sooooo . . . does that mean I do not need a update? --J.D.
