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.
