Issue: Error indicating an Aspyr game will “affect the performance of your Mac.”




If you received this warning, you are likely running an Aspyr game that is a 32-bit app. If you are running on MacOS High Sierra, this should not affect the performance of your Mac at this time.


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


All new apps submitted to the Mac App Store must be 64-bit, and all apps and app updates submitted must be 64-bit by June 2018. With the next version of macOS after High Sierra, Apple will warn users about 32-bit apps before phasing them out. This notification is one such warning.


At Aspyr, 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.


We are currently unsure how long current 32-bit apps will be playable on future operating systems, or how the gameplay experience will be affected.


Players should know that existing 32-bit apps are not known to affect your Mac’s performance at this time.
