CoCGMS Mac Download
The Mac version of the CoCGMS is a runtime build of the software using FileMaker Pro Advanced version 18. FileMaker offers a feature that lets developers wrap a FileMaker database within a dedicated runtime framework that can only run the database it was compiled to support. This is perfect for databases like the CoCGMS allowing it to break out of the lab and into the world.
To use the Mac version of the system, simply download the below archive and unzip to a folder of your choosing. Run CoCGMSv2.app and that's it. No installation. Just unzip and run. You can keep multiple copies of the application in different folders but the CoCGMS is designed to hold separate content in dedicated packages so you normally just need one installation.
The CoCGMS v2.9.0 requires macOS High Sierra 10.13 or better.
PLEASE NOTE: Beginning with macOS Mojave 10.14 and higher, Apple implemented an app signing requirement that the CoCGMS does not adhere to. Because of this, running the app for the first time may result in a crash that is easily remedied. To unsign the CocGMSv2.app executable, run this command from a terminal window (replacing the app path with the path you have your copy of the CoCGMSv2.app file in):
codesign --remove-signature /Users/YourUserID/Desktop/CoCGMS-Path/CoCGMSv2.app
You can also enter "codesign --remove-signature " at the terminal prompt and then drag the CoCGMSv2.app file into the terminal window to drop the app path onto the command line for easy reference.
That will remove the signature on the app and your Mac will happily run the program as intended.
