I finally moved to the Mac mini at work. I have a bunch of programs I need to get installed. I am amazed how fast and snappy things are. It makes me want to get a new computer now. Anyway, the gotcha I came accross was the use of Mail.app with ISU's Kerberos. The best solution is to use kpoprelay to skirt around using Kerberos. Instructions on how to do this can be found at
