MySQL Workbench 6.3 (Mac) hangs on simple queries

When I enter a simple

Answer 1

6.3.9 fixed the issue in the mac. Here is the link MySql 6.3.9

Answer 2

I found that if you use the latest 6.3 version, that in order to get queries to work, you have open a first connection and ignore it and then open a second connection. This creates two tabs in the workbench. If you perform your queries in the second tab, it works. If you try in the first tab, it hangs.

I also have found that you have to do a force quit the workbench.

I hope the mysql folks get this fixed.

This seemed to help some of the time, but not 100%: Connect to the database with a different user, and then re-connect with the original user.

I'm about to downgrade like the accepted answer says though, as this doesn't solve it every time.

Answer 4

I was getting around the problem for awhile by deleting the user library folder and dropping back to version 6.2.5 ... but today found the problem was back. So today I deleted the user library folder and dropped back to version 6.1.7. It's working again, for now.

Answer 6

I found that deleting the cache and workspaces folder contents (~/Library/Application Support/MySQL/Workbench) it works again. What I haven't found is how to ensure it doesn't hang again :-(

I also found that if I manually close the Connection tab from the menu and exit WB from the menu and not from the OS window buttons it seems more stable next time.

PS: I am using SSH connection so it may be due to this but it is not always happening.

UPDATE: A clean install and no SSH configurations the issue still persists. Unless you manually go and delete the cache folder files it continues to hang.
