my macbook was shipped on nov 12th (lastest cpu etc) and i got it on nov 20th. the rom is MB21.00A5.B00 the MacBook EFI Firmware Update 1.0 was released on nov 13th and says after the update the rom will be MB11.0061.B03 so do i need to update? its alittle confusing as my number is higher. my macbook is slow to sleep and come out f sleep compared to my powerbook but nothing weird that ive noticed. and my macbook is (touch wood) running perfectly. i have everything perfectly the way i want it and everything works. i dont want to introduce any problems.
