Tiger 10.4.4. Update WARNING! (CHUD)
I recommend to uninstall older version of CHUD tools.
After I did software update my fans always started to get crazy 2-3 minutes after booting. No matter which app I started, even if any. The fans went so fast and loud I thought they are thinking that the 10.4.4. update turned them into some Rolls-Royce engines (used to "move" airplains) and they probably decided to fly my Mac away...
Then I realized I can not connect to the Internet, because my USB cdma modem "did not exist" even if I checked the connection and the power-on statement...
I uninstalled the CHUD tools and the problems were gone.
There is a new version of CHUD tools from 2006-10-01 available here: http://developer.apple.com/tools/download/
