Download Logisim from SourceForge.

Initially, I downloaded
logisim-macosx-2.7.1.tar.gzbut I encountered errors due to the required java version. What worked for me is to directly run the jar file:
java -jar logisim-generic-2.7.1.jar
tar.gz also includes a .jar file. Show package contents to access:
Logism.app package contents:
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 A newer version of this package is already installed.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.
To resolve this, go to System Preferences -> Security & Privacy.
