I remember on the first couple days when I booted up my macbook, it reaches the log in screen at around 15 seconds or less. However, after I installed windows 7 via vmware fusion, the boot up time increased to around 30 seconds. Now I just removed fusion, the boot up time is still around 30 seconds. Is there any remedy for that? I'm not complaining for the wait, but I'm wondering why the boot up time has increased so significantly. Thanks in advance.
