My Mac and iPhone do not synchronize

Hi there lyndep,

We'll need a bit more information in order to help with your email not syncing as expected. Is this happening with one specific email account? If so, what type of account are you experiencing this issue with? Do you have the email account added on both your iMac and iPhone? What's not syncing exactly? For example, are you deleting emails from one device and they still appear on the other or something else?

Also, you'll want to make sure both your iMac and iPhone are updated to the latest software versions, which are macOS Ventura 13.5 and iOS 16.6. To learn how to update both devices, have a look at the steps in the links below:

Send over the details requested above, and we'll provide some additional guidance from there.

Thanks!
