My Book firewire not bootable on mac

I bought the 500 GB My book after X-mas and started loading the drive as a bootable external drive using the OS CD's and the startup selection program recognizes the 500 GB but won't boot from it.

    I have the exact same problem. Both of my Mybook's load in USB but not from Firewire.  I even downloaded the latest firmware that Western Digital had to offer, but still no change.

    Please help!!!

Western Digital FW hard drives are NOT bootable for Macs. I bought one of their 320 GB FW HDs specifically to be able to create a bootable backup (via CarbonCopyCloner). The Macintosh HD clones just fine, and the WD drive even appeared to be recognized as a valid startup disk in System Preferences, but all attempts to restart with the WD drive as the actual startup drive failed. I subsequently contacted WD who eventually (after several go arounds of inane, irrelevant questions) admitted that their FW HDs have been "modified" to render them non-bootable!
I kept the WD drive for storage but promptly bought a LaCie 500 GB quad interface and that boots my G5 just fine.

I picked up a couple of My Books lately( via Ebay), and noticed that i can not get them to work on the Firewire interface with my Dual Core Intel Mac. Shows up on USB2.0 fine however.I found an online reference that said Apple changed some things on the Firewire interface year or two ago, and that vendors had to update their firmware (it related to Firewire devices reporting a unique ID to the Mac).

Mac loads and runs fine, but every time I try to update the programs on my Mac it keeps asking for a password, I don't know.

Which program were you trying to update? Are you trying to download and install new software (that is not from Apple App Store?) Are you running Mountain Lion (OSX 10.8)? The password needed is your administrator password.

How do i use a wd external drive 500 gb on a mac & pc

The MAC can read and write PC files but not the other way around.
To do this the USB external hard drive needs to be formatted using the PC and formatted in FAT32.
Once this is done then you can exchange data between the MAC and PC.
