Extremely Slow Finder Functions
I upgraded to macOS Sierra a couple of days ago and I've noticed some extreme slowdowns in certain tasks:
1. Moving a file (~200k) from 1 folder to another on the Desktop can take 20-30 seconds - I routinely see a window that says 'Preparing to move filename' in the upper right corner.
2. Opening/Saving files in pretty much any program (although Adobe Illustrator CC 2015.3 is even slower!) - It can take 45 sec to a minute just to see the Open/Save dialog after I press Command-O or Command-S.
3. Application Not Responding messages on many programs (Adobe Illustrator, Adobe InDesign, The Unarchiver, MS Word, etc.) I've lost count of the number of times I've Force-Quit and Rebooted in the last 2 days.
I'm running a 17-inch, Late 2011, MacBook Pro with 16Gb RAM and a 1Tb SS Hard Drive. (And I am linked to a Dropbox for Business account for work - I need to access this a lot for the files that I use.)
Any ideas on what I can do to speed things up a bit? Or should I just downgrade beck to El Capitan?
Thanks!
