Although it is out of the Scope of Technical Support for Blizzard to assist, you can search on your own for a program that will tell you what type of motherboard you have, then visit the manufacturer’s website for the update.

Run Windows Update. The Windows Update link works best with Microsoft Edge or Internet Explorer

Note: The newest service packs may not automatically install when you run Windows Update. You must manually choose to install new service packs in Windows Update.

After the updates have been installed, check if there are additional Windows Updates available.

Mac®

A Software Update is an incremental update of the Mac OS and its applications, Security Updates, device drivers, and firmware updates. For Blizzard games, it is important to download and install all software updates, as our games are designed for the latest version of the supported system requirements.

See Apple's OS X: Updating OS X and Mac App Store app page for Software Update instructions. 

During technical troubleshooting, you may be required to reinstall an OS update or driver. In order to reinstall drivers and files for the latest OS X build, you can download a Combo Update. 

You can find the latest Combo Update for your operating system located on Apple's Support Download page.

When an older OS has no more incremental updates, you will need to upgrade to a new OS to obtain newer drivers and updates. Blizzard titles require version 10.10 or newer to run properly.

Upgrading to 10.10

Follow the instructions in Apple's How to Upgrade guide, to update your Mac to the most recent version of MacOS.
