I had the software for a Vodafone mobile dongle installed on my 10.5 mac which caused a 5 minute beach ball after I installed Snow Leopard. Maybe installing rosetta as prompted would have made it work, but I just wanted to rid myself of this nastiness since I’m not using the dongle any more anyway.
Dear google, this is what I did, YMMV:
Remove the following from /Library/LaunchAgents/
Remove mac_swapperdemon from system preferences user > accounts > user login items
/Library/Application support/Vodafone /Applications/Vodafone mobile connect
Update: also discovered some kernel extensions to remove
sudo rm /System/Library/Extensions/USBExpressCardCantWake_Huawei.kext sudo rm /System/Library/Extensions/ZTEUSBCDCACMControl.kext sudo rm /System/Library/Extensions/ZTEUSBCDCACMData.kext
