This problem has been getting worse for months. Whenever I open any application, email, safari, finder, etc. I get the "spinning beach ball". It takes so long for the program to open that I walk away and do other things. Sometimes the program just crashes or the computer shuts down. I have Malwarebytes. After each scan it tells me my computer is clean. I often have to force quit applications. Recently the top application on the "force quit" list is "front end application". Is there a way for me to fix this or do I have to take it to an expert?
