At firs it was working alright, but out of the blue it disappeared, and there is no way to bring it back. Note the gray area with the Apply and Revert buttons, where the results grid should be.
I also tried clicking on the EXPLAIN command icon, then it opens up the Explain pane, and the results grid is there (grayed out). If I click on it, it disappears.
Any ideas?
Thanks
Good News! 😃
Apparently this is a widespread bug on macOS High Sierra that was fixed in version 6.3.10 that was released Nov. 15th 2017.
They fixed it as described in the release notes: https://dev.mysql.com/doc/relnotes/workbench/en/wb-news-6-3-10.html
Executing a query in MySQL Workbench on a host running macOS High Sierra failed to load the result grid completely, which prevented result data from appearing within the Result Grid tab. (Bug #26826418, Bug #87714)
