Creating partitions on brand new macbook pro

Hi guys,

I've just bought a new 15 inch macbook pro. I want to create 2 additional partitions.

Do you recommend that I:

1) Reformat the whole computer and create 3 partitons, i.e. delete the current one partition, create 3 partitions and instal OSX ML into the main partition; or

2) Go into Disk Utility and create the partitions (when my mac OS is running!) ?

Would there be any inefficiencies with step 2? Thanks in advance!

MacBook Pro, OS X Mountain Lion (10.8.2)

Do it when the OS is running. Unless you need to change the partition table format for some reason, there's no reason to erase and reload the OS when repartitioning from Mac OS X 10.5 or newer.

I might be missing something, but when I open Disk Utility with the OS running, I do not see an option to partition.

Try booting into the Recovery mode (command - R) and run Disk Utility there. You should be able to partition.

I agree with Niel that there is no reason to erase and reload the OS that currently exists, unless for some reason you like installing system software. 🙂 If it ain't broke, don't fix it.
