The ‘Apple’ logo has been commented on by many, and what has been alluded to here is the myth that it is based on the biblical ‘fruit of knowledge’.
Another popular theory is that it represents the apple that Issac Newton observed falling from a tree, as was indeed displayed on the first ever logo.
And perhaps the most popular myth is that it alludes to the poisoned apple that computer pioneer Alan Turing used to kill himself. All of these were presented to founder Steve Jobs, who dismissed them but says he wishes they were true.
