I've read a lot of other questions about speed, but my question does not seem to be answered anywhere. My Mac Mini is running so slow that I cannot see what I am typing. It takes up to 15 seconds to see the text I just wrote. Any process on the computer runs so slow that I see the spinning beachball all the time.
I've looked in the Console and Activity Monitor, and cannot figure out what is wrong. No single process is taking up more than about 10% of the processor and memory is not maxed out.
I should note this is not a very old computer. It is not the most current, but it is fully capable of running Mountain Lion and has a decent amount of RAM. Please help, I'm about to jump outta my window!
