Hello everyone! 
We have just released Blocs for Mac 6.4.3 beta build 1, this release includes some bigger under the hood changes to the font selection menu, so I have decided to run a short beta to make sure everything is working correctly.
There are a few other font related fixes in there too.
Happy Testing 
@Norm you are on fire with the releases lately. Love it!
@norm you barely released a version packed with new features and you’re already launching another one with even more improvements — that’s impressive!
Really appreciate the continuous updates and dedication. Thanks for all the hard work!
the development of 6.4.x is remarkable
