How to remove GroupCal from your Macintosh
After playing with GroupCal a bit, I found that it became more of a problem with calendaring than it helped. It didn't help that since I use multiple computers if I accepted a meeting on one computer, the other computer still forced me to accept the meeting on my Macintosh. Yes, I use windows most of the time. So finally got it configured so it no longer polled my Exchange account for information, and deleted the 'work' calendar I created in iCal, but GroupCal kept running. There was no option to uninstall the Daemon. After a quick email to Snerdware I was able to get a reasonable fix. Do a find for all GroupCal files, and delete them, and reboot.
Not sure how that leaves my startup files... but its worth a shot.
The Daemon
/
Delete that folder which has 'cookies, and GroupCal Daemon in it.
The Application
/
The Preferences
/
com.snerdware.Groupcal.plist
com.snerdware.Groupcal.sources.plist
And you are then cleaned up of this application.
