Hi all, I'm running Leopard (10.5.5) on an Intel g5 iMac. I noticed this afternoon when trying to drop an app into my 'Applications' folder that I had to enter my password in order to do. Checking the 'Get info' pane for the folder I noticed that the permission status for 'everyone' was set to 'read only'. I have no idea how this happened but it must have been fairly recently as I was happily dropping apps into the folder only a few days ago. There are also two other 'names' in the panel labeled as 'unknown', one of whom has read & write permission and one of whom is also 'read only'. There are only two user accounts on my mac and we are both administrators, so I don't know why there are so many entries under the 'Sharing and Permissions' section. So anyway, I unlocked the panel with my password and tried to flip the permission for everyone from 'read only' to 'read & write'. I got the following error dialogue: "The operation could not be completed. An unexpected error has occurred. Error code - 8076." I tried to add a new 'administrators' group to the permissions panel with read and write access but received the same error. Any help would be greatly appreciated. Thanks.
