Possible to make OS X live DVD/USB?

[kris-hm]

I want a live dvd or usb of osx mountain lion or mavericks. Not just a bootable, i want it to be equivalent to linux's live cd where i can boot into a fully functional os. I did a little searching on google but i didn't find much. Is there a way to do this?

You can install the OS onto an USB stick (16 GB minimum) as onto any other drive.
(just choose the stick as destination when prompted).

Warning : the system will be very slow because a USB stick is slower than a 5400 rpm hard drive.

Thanks for the response. If i do this, will i be able to boot it on any mac?
I know that i cannot just take any hard drive from a windows pc and put it in any pc and make it work, the system must be installed on the computer it is going to be used on. I want something that i can use like i can use ubuntus live cd or puppy, where no matter what computer i put it in, it will load to a fully functional os.

You can boot on it only if the Mac supports that system.

For example, you can not use it on a 2007 Macbook White : maximum OS is Lion.

You do not need to have a system installed in the Mac : this will work even if you put a blank new HD in the Mac.

To boot up from the USB stick, hold down the Option key while starting, and select the key on the startup screen, hit Enter.

Again, the system will be very slow : it would much better to use an external hard drive.
(you can install the system onto a 20 GB partition).

I understand, I'm probably going to use a 128gb high speed usb. Don't know if it will make a difference in speed, but it will allow for installation of programs without making changes to the existing configuration on the computer.
Thank you for the assistance, it is much appreciated.
