AppleEvents get the blame for Photoshop issue

Grrr… Apple and AppleEvents are being blamed for an issue with our photo processing.

Our vendor confirmed that we and other customers are impacted and the issue isolated to Mac machines only. The cause being looked at is a recent Mac update delivered via Apple-initiated background process. The update is blocking Apple Events communication which is required for the PhotoShop plugin to function.

I’m trying to get more details (this doesn’t impact me) but I’m just wondering if anyone knows of any recent apple updates that are breaking apple events, specifically in Photoshop plugins.
