Rainbow circle is haunting me!
Every time I try to copy files from 1 HD to another, or even just to move folders around on my desktop, I get the rainbow circle and am waiting ages for anything to happen. What could be causing such delays. NOTE: I have force quit finder several time, restarted the mac several times, unplugged all external devices and restarted as well... but the problem remains? Any help would be greatly appreciated.
MacBook Pro (15-inch, Late 2016), iOS 10.3.3, iOS 10.13.6
