Reminders app on Ventura is blank and unresponsive

Hi mxh3ctr,

Updating to the latest macOS version can help with overall performance, so that's a great place to start. If an update is available, it's a good idea to back up your Mac before installing it: Update macOS on Mac.

If the issue persists, try testing in safe mode. This will start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening, which could help narrow down the cause of the issue. This article will walk you through the steps: How to use safe mode on your Mac.
