Hey, I have been having some issues with my log in screen lately. Whenever I wake up my Macbook from sleep (either opening it from having the lid closes or just pushing a button when the lid is open) it takes about 20 seconds-30seconds for the log in screen to pop up. My friend has a MB and hers pops up almost instantaneously. Mine has a pretty big delay. Any ideas how to resolve this? Maybe a simple Onyx run will fix it.
