So far, I've been dual booting Mac OS X with Ubuntu.

Blessing the Ubuntu Partition will speed up the boot process. Apparently, all I have to do is this:

sudo bless –device /dev/disk0s3 –setboot –legacy –verbose

How can one reverse this command?

  • This question, as João Pinto pointed out below, is possibly off-topic because you are asking for support with Mac OSX. Although you have a separate Ubuntu partition on your machine, the focus of your question is on the Mac bless utility, which we probably can't help you with. – WarriorIng64 Nov 8 '11 at 17:56

    Perhaps this could be migrated to apple.stackexchange.com. – Eliah Kagan Nov 8 '11 at 18:05

"bless" is not a Ubuntu/Linux utility, so is not something we can help you with, probably you will get better help by asking in a Mac OS x support resource. I general if you don't understand how a command works you should not run it.
