iOS 13 Reminders upgrade and Mojave

Reminders in iOS 13.1 and iPadOS 13.1 are not compatible with the macOS Reminders application on Mojave and earlier. This will be rectified upon upgrade to 10.15 Catalina when it is released in October. I believe that Apple offered a caution about the Reminders incompatibility during the iOS 13 upgrade, so users were informed, so to speak of the consequences.

To add to what others have mentioned, check iCloud.com. Your Reminders should still be there.

But you'll have to wait until macOS Catalina is released to share them with your Mac since you Upgraded Reminders on your iOS 13 device. Had you chose Upgrade Later when you first opened Reminders on your iOS device, you would still be able to sync with macOS Mojave.

Not only reminders!! I am unable to sync my imac Calendars with iPhone now. My upgrade to 13 was automatic...big mistake. It seems like with each apple update or upgrade, there are more problems than solutions Becoming disillusioned. So I suppose this means I have to enter events on my iPhone calendar manually!

If you upgrade to iOS 13 on your mobile device you'll lose syncing between that device and your Mac running Mojave for Reminders.

I just got caught out by this. I won’t be upgrading to Catalina so no more reminders on any of my Macs.
