Syncing iPhone 7 Calendar with MacBook Pro

[billwill]

I have many, many important dates, etc. on my iPhone 7 calendar. My MacBook Pro calendar doesn't have very much info on it.

How can I make sure when I plug the iPhone 7 into my MacBook Pro the data ON the iPhone 7 will be synced onto the MacBook Pro? I can't afford to lose any data. I have iCloud set on the iPhone 7.

I'm terrified that when I plug it in, it might sync the BAD data from the Macbook Pro to the iPhone 7, which would be disastrous.

Thank you very much for your help and expertise.

You need to make sure that you have iCloud setup on your MacBook Pro, so goto System Preferences > iCloud and make sure you log into your account. You can then check the Calendars option and your iPhone and MacBook will then stay in sync.

And make sure both calendars show in Settings to Sync All events, otherwise you could lose some historical calendar data.
