Hi, I have a few questions regarding my firmware. 1. Should I upgrade my firmware even if everything works fine ATM? 2. I have 8GB of RAM installed. I understand that years back, firmware had an effect on this capability. Will the newest update break that? MB51.007D.B03 is what I am on now. Update to MB51.007D.003 (EFI 1.3) is available. 1.32f8 (SMC 1.2) SMC is current. Thanks!
