My Mac Pro 4,1 has a big Finder problem. When adding, moving, and deleting a file or multiple files to a folder or any folder, files take between 7 to 10 seconds to appear in a folder when added or moved, and 5 seconds to disappear from a folder when they are deleted. It's an annoying and frustrating lag in Finder. My Mac Pro only has two internal drives and both drives have Yosemite 10.10.5 installed. I don't have Dropbox or any other app that requires access to my Mac Pro. Any Remote Access, Remote Login, File Sharing, Location Services, Bluetooth, Time Machine, and Notification is all disabled. The boot drive is a Samsung 850 Evo 1TB SSD thats on an Apricorn Velocity x2 Solo card and installed in PCIe slot #2 next to the Nvidia GT 120 card. The other internal drive is in Bay 1. I have performed the following diagnostics: Recovery HD Disk Utility - Repair Disk Disk Utility - Repair Permissions Apple Hardware Test, twice - Passed PRAM Reset Malwarebytes Scan - No threats found EtreCheck - No issues found.
