Click on 'General' in the sidebar, then click on 'Software Update' on the right.
If macOS 15.1 or later is available, click 'Update Now' and follow the on-screen prompts to restart and update your Mac.
Isolate the Issue with Safe Mode and Add-ins
If updating macOS does not resolve the issue, use safe mode and disable add-ins to rule out third-party conflicts or corrupted user profiles.
