Hi, I have an iMac Retina 5k, 27" 2017 w 3.8GHZ process and 64gb of memory with a 2t hard drive and iCloud. Since the move to Big Sur (Big Slow) finder hangs and gets spinning beachballs if I try to move a file or folder. I can do this on my other iCloud devices that are on Catalina 10.15.7 without issue. I've rebooted in safe mode. I've remove all start programs. I've reinstalled Big Sur 11.2.3, I've run 1st aid on all drives and they are good. Anyone have this issue and try all these things? Anyone have a fix. I'm out of ideas and I even chatted with support to see if they could help no go there and I'm dead in the water now.
