I have read a lot of stories about APPLE logo and why it's half eaten apple.all i found may be realistic and makes sense is that story and it's One of the most interesting stories I read was that the original rainbow apple logo was a tribute to Alan Turing, an English mathematician, logician, cryptanalyst and computer scientist, whose concepts played a considerable part in the development of the modern computer system.
In1954 he committed suicide, by cyanide poising.
A half eaten apple was found with his body, which was thought to have contained the cyanide.
Hence forth a half eaten apple was a symbol for Alan Turing and his life’s work; and thus the apple logo, with a bite out of it was a reference to this.
Seemingly the rainbow stripes could also relate to this, being an iconic gay symbol.
However, both the company and at the designer however state that there is no real truth in this, as poetic as it is.
