I have a 2010 MBP with 4 GB RAM and 256 GB SSD running El Capitan. When I load any app, Word, Skype, etc., it takes several seconds for the app to start during which I see the beach ball spinning, and the app icon bouncing up and down (I counted 47 bounces before Word started). Is something corrupted, or should this be expected? Once the app starts, then using the app is no problem. When I quit the app (right click -> quit), that takes a few seconds as well. Some apps like the new Turbotax take 10's of seconds, and this is even before it tries to update. Any ideas?
