Important Information 
The latest macOS Tahoe 26.1 update introduced a system-level regression that affects the performance of AI Mask features in DxO PhotoLab 9, as well as in other imaging applications. Our teams are already working closely with Apple, who is actively addressing the issue.
DxO PhotoLab 9.2.1, released today, includes a temporary workaround that forces AI Masks to run on the GPU, ensuring the feature remains usable while Apple prepares a fix. We truly regret this disruption, which stems from changes introduced in macOS and is entirely outside of DxO’s control.
