I have the latest updates for everything (running Yosemite). I'm using this for office work. Just opening the web browser, open Microsoft Word. Its painful, like its from 2005 rather than 2012/2013. Its using a tradition HD rather than SSD, but still... This is bad. Any ideas why it would be doing this? I did a repair disk and permissions and used OnyX for some cleaning and nothing... Startup items are only Dropbox and TotalFinder and iTunes Helper. Any help would be appreciated. Thanks!
