IMAC is Slow!!!!!!!!!!!!!!!!!!!
I'm sharing almost the same thing. My Imac 2010 is extremely slow. I boot up and everytime I click an application it takes about 3-5 minutes for the application to start up, then I click somewhere else and same instance. Its been very frustrating. I tried downloading applications to free up memory and make things faster, but no luck. my next step would be to upgrade memory, but the computer wasn't like this until after loading all of those updates. Do I need to delete everything back to manufacturer settings to get it to speed up again? Sheesh.... 😕
