Newest Lightroom CC on Mac: Many reports of crashing, slowdowns, failed imports

I am seeing extensive reports on social media that the version of LR CC released for Macintosh a couple of days ago (Oct 5?) is causing relentless crashing, slowdowns, and failed imports. Warnings are widespread that we should NOT upgrade to the latest release. I am writing this note to make sure that you are aware of this. Google Laura Shoe if you need more details. Or check any forum.
