Hello, All. Yesterday morning I woke and booted up my shiny MacBook Pro to find something very odd happening. It seemed that every action I performed took 20+ seconds to be executed. I had been experiencing other anomalies from the time I upgraded to Mavericks. Has Apple created a non-stable OS or perhaps something else? It didn't take long for me to decide to call Apple Technical Support on this. I knew something wasn't right and needed a resolution quickly. Luckily, I was connected to a knowledgeable support representative in Austin, TX. After several hours of questions and diagnostics he became intrigued as to the problems I was experiencing. The preliminary diagnosis was a running, hidden process taking up a humongous amount of resources. The Apple rep was stunned and bewildered. They bombarded me with tasks to produce various diagnostic logs and even sent me the Capture Data app, which has never been able to successfully finish. Has anyone else had similar experiences using Mavericks?
