“Photomator” can’t be opened because your device does not support the Metal graphics technology.

Since upgrading Photomator from 3.4.4 to 3.4.5 (via the App Store) I get the following message when attempting to launch the app:

“Photomator” can’t be opened because your device does not support the Metal graphics technology.

Photomator 3.4.4 would launch without any errors or issues and I've not changed anything else.

Current setup:

iMac 27-inch, Late 2013

Graphics: NVIDIA GeForce GT 755M

macOS Sequoia 15.2

OCLP 2.0.0

Anybody else have this issue or can launch Photomator 3.4.5 without any errors?

Many thanks
