Update Safari or Update System Software

Make sure that your Safari is up to date. Safari releases bug fixes frequently that can resolve many problems and prevent them from happening again in future. To keep the software updated and make sure that those bug fixes are working in your favor, follow this procedure:

  • From the Apple menu, go to “App Store” and click on it.
  • Go to the Updates tab and find out any available Safari updates or security updates. If you find any of them, and install them immediately.
  • Don’t forget to back up a Mac before installing any software update. Keeping a backup copy is important for anything that adjusts the system software such as some security updates.
  • You can also go for updating broader Mac OS X system software if there is any newer version available. But there are some Mac users who are comfortable with the version of system software they are currently using. Therefore it is not always advised to go for broader system software.
