So I have 2 users on my PowerMac...My Wife and I. I had set up her account initially, and added myself later. We are both administrator users. It seems though, that I can only install or update (over right) certain programs from her side of things. I have gotten info on the Macintosh HD> Applications folder, and made sure that both users have read and write privileges for the folder, but the files inside don't always reflect that change. For instance I'm trying to update VLC, and it's telling me I don't have sufficient privileges to do so. I know for fact that I installed this initially from her side of the machine, and when I get info on the VLC file that's there my user doesn't show in the permissions and the user group "everyone" is set to read only, which I know I could change, but I want to do it for all of the files in there so I don't have to switch back to her user to simply upgrade a program if i need to. Any help here? Thanks!
