Whenever I click file-open or file-save as in any program, the finder dialog box takes a tremendous amount of time to open (approx 2mins). I have tried all kinds of solutions throughout the web and none have worked, not even temporarily. Most of the fixes I have seen say that good patches came after Mavericks, but I am running sierra. I have had the problem even throughout El Capitan, but it was barely a problem. On El Capitan the longest delay was maybe 10 seconds.
A few things I have tried/noticed
- The problem occurs in safe mode, but it does NOT occur on the guest accounts
- Going into Safe Mode doesn't fix the problem
- Deleting the Finder plist doesn't work
- Deleting Icloud caches do not work
