Mac reminder stop working after iphone upgrade to IOS 13.0
Hi,
After upgrading my Iphone to IOS 13.0, then launching my reminder apps on my Mac, it doesn't sync the tasks from icloud. Reading the apple post https://support.apple.com/en-us/HT210220#other, but I didn't see the option of updating the reminder app in my Mac as suggested. So now my Mac reminder doesn't sync. I tried turned off/on icloud on Mac, still no avail. How do I get my Mac reminder to work again?
iPhone 7
