Errors Encountered:

• When I tried to open Logism.app, it required the Java SE6 Runtime.

  More Info... leads to Download Java for OS X 2017-001

  However, I already have a newer java version installed.

  Java for macOS 2017-001 can't be installed on this disk. A newer version of this package is already installed.

  

  This is when I considered using sdkman to see if I can download Java SE6 but since the version is deprecated, it is not immediately available on the list.

• When I double-click the jar file, the following warning is displayed:

"logism.jar" cannot be opened because it is from an unidentified developer.
