In apples voice/video chat program, it appears that it uses some kind of SIP protocol to communicate. But Apple, why not implement SIP phone ability into iChat AV? Being able to make voice phone calls to other SIP phone systems would be really cool.
I’ve been generally happy with tiger on my powerbook. The Spotlight search really has helped me finding my stuff. But I’ve had problems with slowdowns after working with my computer for a couple of days. I never turn of my computer, just putting it to sleep when I’m done working, and after a couple of days the machine would get slower and slower. I finally gave up and started to search for the problem. Turned out that Dashboard (when loaded) ate memory like a hog! My guess is that their is a memory leak when using some of the widgets. But for me, Dashboard is to slow to be of practical use for me, so I opted to disable it. And now the machine works great again.
If your interested in disable Dashboard, do the following:
Open Terminal (you’ll find it under Applications/Utilities)
Type defaults write com.apple.dashboard mcx-disabled -boolean YES
To enable it again, write defaults write com.apple.dashboard mcx-disabled -boolean NO
I got fed up with the fan that’s running constantly on my Powerbook 12″ rev b 867mhz after installing the 10.3.8 Update. So here’s how you do it:
- Download Update 10.2.8 and use Pacifist to extract /System/Library/ExtensionsAppleADM103x.kext from MacOSXUpdate10.2.8.pkg to the desktop.
- Do a backup of AppleADM103x.kext from your startup disk at /System/Library/Extensions to your home folder.
- Copy AppleADM103x.kext from your Desktop (the one you extracted from 10.2.8) to /System/Library/Extensions, you’ll need to enter the admin password to do that. Start Disk Utility and do a repair permissions on your start volume. Problem solved. Just for good measure, reset the parameter-RAM by holding down Command-Alt-P-R at startup. My machine now turns on the fans at 148 Fahrenheit instead of 125 Fahrenheit.
For some reason Apple choose to change the temperature when the fan starts on Rev.A Powerbook 12″ after Mac OS X 10.2.8 from 148 Fahrenheit to 125 Fahrenheit. This gives the result that the fan runs almost constantly due to the fact that the powerbook operates normally at 125 Fahrenheit. I did this hack back when Apple changed stuff in the 10.3.2 update, and they haven’t updated AppleADM103x.kext until 10.3.8.
Another thing to note is that I tried to do the Install option from Pacifist instead of the copy to the desktop. That didn’t work. My guess is that it has to do with the kextcache. maybe you just have to do a sudo kextcache -e or similar to get the kext cache to update? Haven’t tried it though.
Just a reminder, I take no responsibility if you do this hack and something goes wrong.
After updating to 10.3.8 Apple managed to lower the temperature that the fans turn on and off. So now when doing medium light work the fan goes on. And it drives me crazy. My guess is that they only changed the values one or two Fahrenheit, but it’s just at the point where my normal work load is. I tried the old trick to replace the kext for the fan control, but to no avail.
I just upgraded to 10.3.8 and Apple has managed to fuck up it up for the second time. On my Powerbook G4 867 12″ the fan now runs constantly. This is the second time a software update has done this. But this time it’s worse, now it’s on constantly, not just when the computer is a little hot. This is going to drive me nuts, so I’ll probably try to replace the kext driver for the fans later on. That was the way to do it the last time. So if your running a Powerbook G4 12″ (first model) wait a bit if you don’t want to listen to a constant breeze…
