My finder is just running incredibly slow. I use it for Premiere Pro, video editing. I understand this is using a lot of processing power but it was never this bad. I would click on finder and it would take sometimes several minutes just to move to the next highlighted file. It's getting ridiculous. I have installed 2tb of storage and currently have 538gb free. My friend suggested maybe having 400 gb of stuff is slowing it down? I have been cleaning it up so far, but I never had this problem before with 400 gb of stuff. Could it be an update that is making it slower, maybe there is a cache building up that I should clear? I'm not sure. I also have it on windows save for web browers, so when I quit it saves the window, is that a potential problem?
