Mac Security Update

Apple has issued another security update that affects Macs using version 10.4.5 and newer. To get it, go to the Apple in the upper left and select Software Update. It's a 45 MB file so it will take a few minutes to download. Installation is automatic and you won't have to restart.

Not sure what version you have? Click on the Apple in the upper left and select About This Mac. A window will appear with the version number.
