Do I need to show my Hong Kong and Macao Pass to transfer from Shanghai to Hong Kong and San Francisco?

No need. According to the data of Shanghai and Hong Kong, it is not necessary to show Hong Kong and Macao entry and exit passes for connecting flights to San Francisco. You don't need a Hong Kong and Macao Pass to transfer between China Mainland and Hong Kong. You can enter the country for 7 days with your passport and return trip. If you only transfer in China Mainland and Hong Kong, you don't need to take the transfer channel directly to enter Hong Kong, so you don't need a Hong Kong endorsement.
