Hi. since moving to Mavericks I have these small, yet frustrating issues. Maybe someone here knows a solution. Thanks in advance. The first issue affects my 15' cMBP - sometimes after deleting a file, the trash icon won't change to "filled", therefore I can't empty the trash. I have to open the trash in finder and empty it from the menu. I know it's a small bug, but an annoying one. The second issue affects the 13"cMBP... the volume icon is sometimes greyed out and unresponsive. I'd found a solution on MacRumors - going into Activity Monitor and quitting "coreaudio" process. But that only helps for a moment, because the greyed icon can reappear anytime (after reboot). Does anyone know a permanent fix or it's just a bug and I gotta wait for Apple fix/update? Thank you in advance for your suggestions.
