Everyone who are new and seasoned users of the Macintosh. Seeing that Apple had finally released the long anticipated OS 10.5.7 update. I want to once again reiterate the steps I normally take for applying OS X updates. Before you start, if you're using a notebook Mac, you should ensure the power adapter is plugged in (of course to the wall also).
Here are the steps I recommend my friends to follow:
- Ensure all your Apple applications; the ones that came with your Mac, are in their original locations, within the Applications and Utilities folders respectively.
- Start the Disk Utility application found in your Utilities folder, and perform the Repair Disk Permissions operation on your startup disk (aka. Boot Up drive); this is normally the first drive you see in the list of hard drives. The "Repair Disk Permissions" button will stay dimmed unless you highlight the volume of your startup disk rather than the disk itself.
- Ensure no applications are running. If you really want to be safe you can restart your Mac in Safe mode, but this is rarely necessary, especially for a dot-dot update.
- Mount the .DMG file of the OS 10.5.7 Combo Updater you downloaded from Apple and begin performing the update.
It is best, if you do not use your Mac during the execution of the update. Of course, you should not interrupt the update either.
If anything goes wrong, you can always rerun the Combo Updater. I hope this helps!
