Will toast let me burn a iso file to a dvd-r? basically I want the DVD-R to be playable on my DVD PLAYER..
if its not a DVD-Video ISO then no
but like Eidorian said, yes you can use either Toast or disk utility
to use disk utility you need to mount it then click the burn button in disk utility, in toast there is a way to have it burn from an image, but i cant remember specifically how.
this isnt really a question for this forum, as it has NOTHING to do with macbooks or macbook pros, people in the mac apps forum will be much better equipped and willing to help you with this question
