After a lengthy stretch of testing over the summer months, we have finally released Blocs for Mac 6.4.7. 
If you plan on upgrading to macOS Golden Gate later today, then I would recommend updating Blocs to 6.4.7 to get the best experience.
As with all new versions of macOS, I’m sure there will be some more issues that crop up over the coming days / weeks, but don’t worry, we will get those patched up to keeps things running smoothly.
If you run into some issues and need an older version of Blocs 6, you can find all versions on the release notes page (scroll down).
And as always, big thanks to all who have helped test and put forward feedback during the testing of Blocs 6.4.7.
