If you don’t want to get your head full of technical talks, just pay heed to these ones as they appear more frequently than you may have heard.

#1 Too Many Programs at Startup: Slow computer startup? Slow Mac? The majority of downloaded programs want to find their spots in the background. But, you don’t need all of them as you start.
