I keep getting the round icon that circles whenever I close or try to start another process
Whenever I close or open a document, or change from one thing to another, I get that revolving icon that looks like a fan in color. It can take a long time before it lets me go where I want.
I am using Yosemite 10.10.5 on my MacBook Pro (13-inch, Mid 2012).
Please advise
