Contacts not syncing between macOS and iOS without using iCloud

I have macOS 26.1, iOS 26.2

iPhone and Macbook wont sync contacts. Did on to macOS and it wont be added to IOS, and vice versa.

However if I sign in to iCloud and add it there, it appears on both!

Why???

This is expected behavior. macOS and iOS do not sync Contacts directly between devices anymore unless you use iCloud or another online account.




What’s happening:


• Contacts added locally on the Mac stay on the Mac


• Contacts added locally on the iPhone stay on the iPhone


• When you enable iCloud Contacts, Apple uses it as the sync service, so changes appear on both devices




Apple removed direct Mac ↔ iPhone contact syncing years ago. Finder/iTunes syncing no longer handles Contacts — only backups, media, etc.




Important note:


Even if both devices are signed in with the same Apple ID, Contacts will NOT sync unless a sync service (iCloud, Google, Exchange, etc.) is enabled.




Options:


Use iCloud Contacts (recommended)


Mac: System Settings > Apple ID > iCloud > Contacts


iPhone: Settings > Apple ID > iCloud > Contacts


Use another account (e.g. Google, Exchange, CardDAV) on both devices


Manually export/import contacts (not automatic)





Nothing is broken — this is how modern macOS and iOS are designed.
