Photo Mechanic® 5 is a 32-bit program and is not compatible with the new macOS 10.15 Catalina.  Photo Mechanic 5 still runs on computers using operating systems released before Catalina, but it is no longer being updated.

The good news is that Photo Mechanic 6 is a 64-bit program that is fully compatible with macOS Catalina. If you purchased Photo Mechanic 5, you may also be eligible for an upgrade discount. We encourage you to take advantage of our free 30-day trial before upgrading. 

You can find more information about Catalina and Photo Mechanic in our blog.
