I'm using a mid 2009 white macbook (it's a pretty old piece of hardware) and I've noticed that the boot time has increased compared to OS X Lion. From the moment I press the power button, it takes exactly a minute to display the login screen. I've tried resetting PRAM and SMC, and have repaired disk and disk permissions. But there was no change in boot time. Is it supposed to be this slow? My macbook has 4GB of Ram and a 5400rpm HDD. Running OS X 10.10.5, Windows 7 installed on bootcamp partition.
