Tonight I was trying to run Onyx and got the "Cannot Verify Permissions" error, so I booted from the 10.4 install disc and got the dreaded "Disk Utility Lost Connection with the Disk Management Tool" message. I've searched all over and the only solution I could find involved deleting the iTunes packages in the receipts folder....only one problem, I already did that 3 months ago when I first got this error. I double checked and those files are still gone, so that's not it. Like I stated above, I ran into this a few months ago, followed the instructions, and have verified/repaired permissions weekly ever since then with no error. I don't think I've installed any new apps or updates since the last time it ran successfully. Are there any other solutions to this problem? Any other package files that need to be moved and/or deleted?
