Keeping Your Software Up to Date
When you’re connected to the Internet, Software Update checks periodically to see
if updates are available for your computer. You can download and install these free
software versions, drivers, and other enhancements from Apple.
You can set how frequently your iMac checks for updates in Software Update
preferences. To check manually, choose Apple () > Software Update. For more
information about Software Update, see Help Center (click Help in the menu bar and
search for “Software Update”).
You can find the latest information about Mac OS X at www.apple.com/macosx.
If you have a problem with software from a manufacturer other than Apple, contact the
manufacturer. Software manufacturers often provide software updates on their websites.
