Hi all. I have a question about installing downloaded apps from a normal user account. In particular from disk images. Lets say I download a new app that is contained in a disk image. The disk image is mounted, and opened. At this point I either drag the app to the application alias provided by the developer, or straight to the application folder. Since I'm in a normal user account, I'm prompted to authenticate with a administrator user name and password. I do this and the app package is transfered to the application folder. Now, if I use "Get info" to view the permissions for the app I just installed, it will show my normal user as the owner with read & write permissions. I've said all this to ask, if I need to authenticate moving the app to the applications folder, should not the ownership of the app package now belong to the administrator account that authenticated? It would appear to me the authentication is only to move the app bundle to a location that my normal user has no write permission. If this is correct, why would my normal user still be the owner with write permission on the app bundle? It's like having write permission on a file, that is in a folder where I have no write permissions. Can anyone shed a little more light on this? Would there be any merit in manually changing the permissions of the app bundle?
