Erick, Thank you, and sorry for 'beginner' questions!
So, I've installed a second version of Java. I believe 8? (Titled: oracle65-1.8.0.172), and I turned it on for the local Solr-6.6.3 folder. Double checked it's using that version (using homebrew, cask and jenv) But... I'm getting exactly the same error still. no such file, and the console.log Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. Unrecognized VM option 'UseParNewGC' Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. thoughts?
