I have a new MacBook Pro 13 inch 2.4GHz and I am noticing that the start up timeis about 60 seconds from power on to launching Safari.

Is this an average start up time?

Yes. Your start up time is dependent on how fast your hard drive is, how full it is, and how your OS is running. If you're running a normal 5400 RPM drive with around 50% of the storage space filled, 60 seconds is about normal. A few things you could do to help this out are:

Reset the SMC

  1. Shut down your MacBook Pro

  2. Plug in the MagSafe adapter and make sure it is charging

  3. Simultaneously press the shift + alt + control + Power buttons and hold them for about 10 seconds. Let go after that.

  4. Restart your Mac (and move on to the following suggestion):

Reset the PRAM

  1. Press the power button to start up your MacBook Pro

  2. Hold down the following keys: + alt + P + R until you hear the start up chime sound twice.

  3. Let go and boot normally.

Disk Repair

  1. Open Disk Utility from /Applications/Utilities

  2. Select your startup volume, probably named "Macintosh HD"

  3. Click on Repair Disk

Permissions Repair

  1. Open Disk Utility from /Applications/Utilities

  2. Select your startup volume, probably named "Macintosh HD"

  3. Click on Repair Disk Permissions

Nope. It should be about half or less.

Try this:

  • PRAM reset

    1. (Re-)start the computer.
    2. Press and hold the ++P+R keys.
      You must press this key combination before the gray screen appears.
    3. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  • SMC reset

    • The procedure depends on what kind of Mac you have. Follow the link and go to the section Resetting the System Management Controller (SMC) to see what you have to do.

MacBook Pro 2011 15 seconds restart time After having my Logic Board replaced it restarted in 45 seconds but that was quickly fixed with, during power up, OPT + CMD + r + p and wait for second chime. This resets the PRAM. It is again restarting at 15 seconds.

60 seconds is rather long (although mine doesn't do much better...). And their seems to be a lot of people suffering from this problem... (on Macrumors and the Apple Discussion forum are some reports of people with problems like you).

You could boost your Mac performance if you like. Here is a good tutorial how to boost up your Mac Startup process.

And if that doesn't help you out, here is a wiki where they go something more in depth about the start up process.
