EFI update for MacBook

by Volker Weber

This EFI Firmware Update fixes known start up and wake-from-sleep issues on MacBook computers. If the firmware update doesn't run automatically, open it manually in the /Applications/Utilities folder.

You will need to read the instructions.


Verpasst? Das ist schon eine Woche alt -- oder gibt es ein neues, das mir entgangen ist?

I recently bougth a MacBook Core 2 Duo and sold my MacBook Pro, because I wanted a more mobile laptop.

Now I am quite unhappy, the MBP got quite warm, but the fan never really ran. It was a very, very quiet machine. The MB on the other hand is getting loud, really loud, quickly under load and even when there isn't much to do it emits noise from, I guess, the fan or the hdd.

Am I the only one experiencing this problem? I am especially interested if anybody else MB is emitting noise even when idle? This annoys the heck out of me in a quiet environment.

Mariano, actually the C2D machines should be a bit cooler then the CD driven ones. The new processor has an increased TDP, but Apple also increased the default fan's speed.


However, you could try to increase the fan's default rpm from 1800 to 2500. This keeps the MB way cooler and should therefore avoid short peaks where the fan turns up.

The other way is to buy a Hewlett Packard LaserJet 9050. Even in idle mode the printer does cover any other noise in our office. :-)

This one might help as well:

my intention was to reduce noise not to raise it ;-) Have to go for the printer then ;-)


thanks for the tip. Will probably also keep my ears warm on long winter nights.

Mariano, even if I shut down my printer, I am usually not able to hear the fan below a speed of 3500-4000 rpm... And this only happens if it comes to 'gcc' and 'javac'...
Maybe the iCurve makes the difference?

There is also an EFI update for the MacBook Pros as well (V1.2).
