Recently the trackpad tap of my MB pro Penryn (march 2008) stops working often and than I need to go to system trackpad preferences before it starts working again. Also I have sometimes that keys keep repeating while typinggggggggg I had my keyboard replaced for that 4 months back, but now I do not have Apple Care anymore... For that last problem I reinstalled OSX but with no result. I downloaded firmware updates for the keyboard and trackpad but when installing I get the message I dont need to install them. Any advice??
