Today Apple released Mac OS X 10.7.3 the 3rd major update to Mac OS X Lion. To eliminate any potential issues, we generally recommend to update any supported systems using the standalone Combo installer, and not the built-in Software Update.













Be sure to back up any important data, and if possible clone your hard drive before applying the update. If you have any issues post-update, boot using UniBeast or rBoot
