I recently installed a new hard drive in my MacBook and now it seems that some of my permissions are messed up. For example, iCal won't open. When I click it, nothing happens, then its 'not responding'. When I hit 'Get Info' it tells me that 'system' is the owner whereas it used to say 'andrew'
I have 4 HDDs and multiple user accounts on my mac and have permission problems all the time. Often they are are causes of Application crashes. Be careful with ONYX etc. Especially Applejack. I find them to be the cause of permission issues. After a 'Cleanse' by one of these applications I always check each HDD by opening it in the finder and checking the bottom left corner of the window. If you see a pen with an x through it your permissions are screwed up. It is normal to see this on the root your system drive if you are in a non admin account. If you want to restore access in the 'get info' box you have options to reset permissions in the "Ownership and Permissions" tabs. When I encounter wiered applications crashes this is often the cause.

Permissions in any OS, in order to use thrid party applications to maintain permissions, the optimal install for these applications is before the hardware/applications are ready for daily usage or before "going online". But after ALL APPLICATIONS ARE INSTALLED. Permission based repairs are taken from a baseline snapshot so to speak, so all repairs to the permission files after the fact are ccompared to original snapshot " user correct permissions. If third party applications are installed at a later date your system needs to be 100 % correct or you will/can experience permission errors until a new baseline is established and stored.
