How can I fix calendar sync between MacBook Air (IOS 15.3) and iPhone 18 (IOS 18.3)?

My calendar has stopped syncing between my Mac book air (with IOS 15.3) and my iPhone 18 with IOS 18.3. Is there anything I can do?

First thing ... verify that sync'ing is enabled. Connect your iPhone to your MBAir with a USB cable. Open a Finder window and in the sidebar select the iPhone. At the top of the resulting Finder window, click Info. Check to make sure Sync calendars is enabled (checked).

thanks so much for your reply. I appreciate it.

I connect iPhone and MB air with USB cable and followed your instructions. The resulting message said that the calendar and contacts were synced. Alas, when I look at my MBair, the calendar items from my iPhone were not found on my computer.

I am worried that the disparity in IOS capabilities is making sharing data impossible.

Or am I crazy! thanks.
