About the OS X Yosemite v10.10.1 Update

The OS X Yosemite v10.10.1 Update is recommended for all OS X Yosemite users.

Updating your system

  1. You should back up your system before installation. To do this you can use Time Machine.
  2. Do not interrupt the installation process once you have started to update your system.
  3. You may experience unexpected results if you have third-party system software modifications installed, or if you've modified the operating system through other means.
  4. Use Software Update to check for the latest Apple software using the Mac App Store, including this update.
  5. Other software updates available for your computer may appear, which you should install. Note that an update's size may vary from computer to computer when installed using Software Update. Also, some updates must be installed prior to others.

 

You can also download the manual update installer. This is a useful option when you need to update multiple computers, but only want to download the update once. Standalone installers are available from Apple Support Downloads.
