How do I get "tap to drag" working again with El Capitan?
After migrating from an older MacBook Pro to a newer one from a Time Machine backup with El Capitan, I found that "tap to drag" no longer works. Is there a way to reenable this functionality? Tap to drag works on my older MacBook Pro with El Capitan installed.
MacBook Pro with Retina display, OS X El Capitan (10.11), Mid-2015
