Upgrade my MySql Workbench 6.3.4 to 8.x fails in db connect

[Steve Emmett]

I've been using MySql Workbench 6.3.4 for several years and decided to upgrade to 8.0.19. The upgrade works fine in that the application starts, i can see local table definitions and some ERDs. The issue occurs when I try to connect to my MySql database (5.7.26).

Whereas the 6.3.4 version works with a socket connection, the same connection (copied by the install i am assuming from from the 6.3.4 install) on 8.0.19 does not work. I get a "failed to connect to mysql using local socket/pipe at /applications/mamp/tmp/mysql/mysql.sock with user steve" - wrong or unknown protocol.

I've tried converting to tcp/ip with the same issue - no connection. I am assuming something has change in 8.0.19 that wrecks the previously working connection.

Anyone have any ideas?
