Lately, I've been noticing my MacBook Pro takes longer than usual to boot. It goes like this: 1. Startup Chime! Grey Screen 2. Sits for a while at the grey screen... 3. Apple Logo comes up 4. Spinning icon (quick) 5. Boot is complete Its when it sits at the grey screen before the apple logo that takes forever (20 secs), after that its like a normal boot. Suggestions?
