If you are an iPhone user and if you take a lot of photographs and videos then surely you transfer it to your macBook. There are two ways - first through AirDrop and second through Photos app using lightening cable. Using AirDrop seems to be the most optimal way which results in lesser corruption as whenever I have tried massive amount of photos and videos using Photos app via lightening cable, it has always led to data corruption and irregularity. 

Hence, if you want to transfer the photos and videos from your iPhone to macOS perhaps choosing AirDrop is the safest and best bet.
