The apple symbol is an apple with a bite.

One theory is that Jobs and Woz decided to set up a company. They thought of several names. After Jobs came back from a trip, he suggested to Woz that the company should be named Apple Computer. As can be seen from the first apple logo, this apple is the one that fell on Newton's head nearly 400 years ago.

There is another and more credible one: Apple Computer uses the bitten apple as its trademark to commemorate this great pioneer in the field of artificial intelligence - Alan ·Turing. On June 8, 1954, Turing was 42 years old and entering the most glorious creative peak of his life. One morning, the housekeeper walked into his bedroom and found that the lamp was still on and there was an apple on the bedside, with only a small part bitten. Turing was sleeping on the bed, and everything was as usual. But this time, Turing fell asleep forever and would never wake up again... After autopsy, the forensic doctor concluded that the death was caused by highly toxic cyanide. The apple was soaked in a cyanide solution. But the outside world said that he committed suicide by taking poison, and this is how a generation of genius ended his life. Later, Jobs, a fan of Turing, named the company Apple and used a bitten apple as its logo.
