My iMac is taking so long to wake up and open any app
My iMac is running excruciatingly slow. Takes forever to wake, takes forever to open any app. Spending more time with the pinwheel than doing anything else. It's an iMac 16,2 runs Monterey 12.7.4. Activity monitor says CPU is mostly free. Does Apple have some kind of diagnostic that would id the problem? What to do?
