I’ve had some bizarre problems with my DNS today. I checked /etc/resolv.conf but everything looked ok. Checked the settings dialog for my network and at first glance, that one seemed ok as well.
But normally there should be a dimmed version of the DHCP assigned values there.
Just select the empty one and press the minus sign. Sneaky little bug there!
Save your settings and you should be good to go.
There’s a problem with getting Perian to work in Snow Leopard. But there’s a quick fix outlined here, but If the PreferencePane is installed to only the current user, you need to paste the following into the terminal:
cd cd Library/PreferencePanes/Perian.prefPane/Contents/Resources/Components cp Perian.zip ~/Downloads cp CoreAudio/A52Codec.zip ~/Downloads cp QuickTime/AC3MovieImport.zip ~/Downloads cd ~/Downloads unzip AC3MovieImport.zip unzip A52Codec.zip unzip Perian.zip sudo mv Perian.component/ /Library/QuickTime/ sudo mv AC3MovieImport.component/ /Library/QuickTime/ sudo mv A52Codec.component/ /Library/Audio/Plug-Ins/Components/
