Can I transfer data from my iPhone to my MacBook

Contacts are tied to your email account or icloud account.

You can add the account to the Mac and it will sync down the contacts.

Videos and Photos in the Photos app, can be transferred to the Mac using the Photos App, or Image Capture.

Link-> Transfer photos and videos from your iPhone, iPad, or iPod touch to your Mac or PC - Apple Support

Link-> Transfer images in Image Capture on Mac - Apple Support

Depending on the specific data it may be possible, or it may not be.

What exactly are you trying to transfer?
