okay, im seriously tired of this question, but here is the answer.
pepakura will not work on mac. the only way is to use some random program that allows windows programs to work on make. however this will not work for ever. only a short time. unfortunatley tammasoftware has not planned a mac version.
second, pepakura is a unique program and hasa copyright on it, meaning no body can create the program again for another 15 or so years. pepakura however is reasonabley new so that is not goin to happen any time soon.
my advice, download pepakura and usea friends pc to run it. or just borrow your friends pc for the time being until you geta laptop or some cheap computer that is windows so you dont have to borrow. hope i helped.
but the amount of times this question has been asked is unbelivable. are you sure you read the stickies?
