I have a MacBook Pro running Mavericks (10.9.1), with 2.8 GHz Intel Core i7 and 16GB RAM. I have recently noticed that it is taking what appears to be quite a long time to startup after being shut down. It sits on the metallic apple logo screen for around a minute. I am sure it never used to take this long but generally I only put it to sleep rather than a complete shut down so not sure if this is a normal time for startup. Any comments would be appreciated.
