'[GAME] is not optimized for your Mac' alert.


If you're seeing this warning, you are likely running an Aspyr game that is a 32-bit app on macOS 10.13.4 (High Sierra).

At the 2017 Worldwide Developers Conference, Apple announced that High Sierra would be “the final macOS release to support 32-bit apps without compromises.”  Read the full support KB article from Apple here.

We are currently working on updating our most popular 32-bit apps to 64-bit to ensure future playability. The roadmap for releases and updates is currently unknown. This transition does present unique development challenges, and it’s not yet known if every Aspyr game will be upgraded.

To ensure playability of your favorite 32-bit apps we recommend waiting to upgrade to a new macOS beyond High Sierra until we are able to verify 32-bit functionality.
