I’m a record producer and for kicks and giggles I got a wild hair to try out the GM candidate today. What a mistake that was! Apple’s very own Logic Pro X is a wreck. It doesn’t even recognize hundreds of plug-ins that are installed. I also noticed a lot of GUI anomalies system wide, like for instance populating icons in the applications folder was sluggish. Good thing I did a full backup of 10.12.6. It appears that my transitioning to High Sierra will be a long time coming, if ever at all.
