Repair Permissions on a Mac

A professor recently asked me about his home computer acting a little strange. One of the things that I’ve found useful to do on a Mac which is acting weird is to run a procedure called “Repair Permissions”. To do this:

1. Open your Applications Folder
2. Open the Utilities Folder
3. Run the Disk Utility program
4. Select the Macintosh HD from the list on the left and click the Repair Permissions button

Once that is done, restart the computer, and hopefully things will act better. I’d also recommend making sure that your computer is up to date by checking for system updates in the Apple Menu.
