This message may appear when you upgrade to macOS Mojave and launch Photo Mechanic 5 (or earlier). If you select OK, the alert message will disappear, and Photo Mechanic runs as expected.
Why you see this message: While both 32 and 64-bit applications work on Mojave, future updates, including macOS Catalina, removes 32-bit support and will only run 64-bit applications. The warning message is to let you know that Photo Mechanic 5 is a 32-bit application that will no longer work with future macOS updates. This alert does not mean Photo Mechanic is incompatible with your computer.
Photo Mechanic 5 is compatible with macOS 10.6.8 (Snow Leopard) to Mojave. Photo Mechanic 5 will not run in macOS Catalina or any future macOS updates.
