Keep your permissions up to date is critical
Having trouble copying or saving files? it could be that your permissions are up the creek!, it should be something we all do at least once a week, but we always put it off and onething leads to another and its forgotten, that is until we start to have problems.There is a remedy and it is very simple, just open up the Disk Utility which you will find in the Applications/Utilities Click your hard drive and hit repair permissions, it will probably find loads of files and directories that it will attempt to repair, once it has finished start it over again until it finds nothing to repair and your done.
