Solr frustration

I went through the steps of setting things up and had a working solr server…until I realized that Drupal search api only works with up to 6.x 

So, I downloaded Solr 6.6.3 … and it won’t start.

“Waiting up to 180 seconds to see Solr running on port 8983Still not seeing Solr listening on 8983 after 180 seconds!
tail: /Applications/solr-6.6.0/server/logs/solr.log: No such file or directory”

I tried 6.6.2 and 6.6.0 

I also tried on a different port, just to see. How can it say no such

I tried using Sudo, instead of bin/solr start

I know this isn’t a Drupal question per se, but has anyone experienced this? Java’s installed. I’m on a mac 10.13.3

Still waiting for confirmation from the Solr message list, and trying to figure out where to ask for help

Drupal version:
