I have only been using Macs since February so I am somewhat new. One thing that really pisses me off is how slow Finder is especially when opening folders from a network share. It car take a minute or two sometimes to open folders from my NAS that have lots of files in them (anywhere from 200-500 pictures). Why is Finder so slow? Is it a Unix thing? I also run Linux on my mid 2014 rMBP and it's the same thing there too. Windows Explorer has no trouble opening these same folders. It usually takes 3-4 seconds to open folders that have lots of files in them. I find Finder unacceptable. I don't really like using 3rd party programs but I may have to try a 3rd party file manager. Any suggestions?
