Yesterday, Sugarsync prompted me to install an update. After installation, it complained parts of it was installed separately and refused to run. I uninstalled it via /Applications/SugarSync\ Manager.app/Contents/Resources/SugarSyncUninstaller.command
Then I did a fresh install. Still no luck, it kept crashing. I fired up the Console to see if I can find any errors. I found some errors related to xfsmond, particularly:
10/11/11 5:43:46.788 PM [0x0-0x57057].com.SugarSync.Manager: launchctl: Error unloading: com.sharpcast.xfsmond
I fixed the permissions of the Launch Daemon for it via
sudo chmod 644 /Library/LaunchDaemons/com.sharpcast.xfsmond.plist
And loaded it via
launchctl load /Library/LaunchDaemons/com.sharpcast.xfsmond.plist
Voila, now SugarSync Manager runs fine, no more crashes. Hope this post helps someone…
