hi @DevotionGeo - I now use sdkman to switch through my Java versions.
Here is the usage page.
On a mac the java sdks will be installed :
/Users/<you>/.sdkman/candidates/java/
In my case I have the following
/Users/<user>/.sdkman/candidates/java/11.0.2-open
/Users/<user>/.sdkman/candidates/java/12.0.2.j9-adpt
/Users/<user>/.sdkman/candidates/java/15.0.2.j9-adpt
current -> /Users/<user>/.sdkman/candidates/java/11.0.2-open
current is a symbolic link which points to the version you are currently using, so from inside an IDE you would have to point to the real folder.
Not sure of that helps you at this stage.
