Addresses an overheating issue in a MacBook
Apple this week posted an updated firmware for MacBook owners that appear to address an issue regarding random shutdowns. The firmware said Apple, updates a critical SMC monitoring component to improve system stability as well as solve the intermittent shutdown issues. Apple is usually thin on details when it releases new firmware upgrades for its line of notebook computers but this time did indicate that users with OS X version 10.4.6 or earlier will have to perform a system update to 10.4.8 in order to install the new firmware.
previously reported that
many MacBook owners were complaining about random shutdowns
. One well known report suggested that the problem was related to a short wire that linked a system temperature sensor to the MacBook's main logic board. Because the update was just released this week, it's unknown how well it has resolved the above issue.
The MacBook as well as its bigger brother the MacBook Pro has been covered here at
since their respective launches. Just this week I had my personal MacBook Pro (2.16GHz Core Duo) repaired under warranty. My MacBook Pro was already running quite hot (just like every other unit out there), and the situation did not better itself when the right fan in my MacBook Pro failed.
Using a tiny application called
, I was able to increase the minimum RPM of my left fan as well as prove to the Apple reps at the Genius Bar that my right fan had died. smcFanControl allows users to adjust the minimum RPM speeds of both fans inside their MacBook or MacBook Pro units. The two fans can be adjusted in sync or independently. Under heavy load, the fans will still increase in speed automatically from the minimum custom setting -- unless you set your fans to a maximum 6000 RPM.
After Apple replaced the "inverter", the main logic board as well as the right fan assembly in my MacBook Pro, everything checked out well. However, MacBook Pro users should keep in mind that using smcFanControl is what will help reduce the heat in their notebooks. Previously, having my MacBook Pro plugged in on AC power it was nearly impossible to use the notebook on my lap. Apple sets the minimum fan speeds at 1000 RPM, and they do not increase in speed much until the system is under heavy load. Using smcFanControl to set the fans at a minimum of 3500 RPM, I am now able to use my MacBook Pro on my lap without a single issue -- it's that cool.

So the Sheeple refuse to believed an infallible Apple product had a 50% failure in it's cooling system? That must be MS's fault, too.

It is. There was a virus in the Windows PC that was used to design the fans.
